Choroby zakaźne
Epidemiologia
Epidemiologia chorób zakaźnych stanowi fundamentalny obszar zdrowia publicznego, zajmując się badaniem mechanizmów pojawiania się, rozprzestrzeniania oraz kontroli chorób zakaźnych na poziomie populacyjnym. Kluczowe znaczenie ma tu nadzór epidemiologiczny, który obejmuje systematyczne zbieranie, analizę i interpretację danych zdrowotnych w celu monitorowania obciążenia chorobami, identyfikacji ognisk oraz oceny skuteczności interwencji. Wyróżnia się różne typy nadzoru, takie jak bierny, aktywny, oparty na społeczności, seronadzór, nadzór ścieków, syndromiczny, cyfrowy oraz genomiczny, które dostosowuje się do specyfiki choroby i celów epidemiologicznych. Przykładowo, nadzór bierny opiera się na zgłaszaniu przypadków przez placówki medyczne, natomiast nadzór aktywny polega na proaktywnym poszukiwaniu wszystkich przypadków w populacji. Warto podkreślić, że skuteczny nadzór wymaga terminowości, reprezentatywności i spójności danych, co umożliwia wczesne wykrywanie ognisk oraz monitorowanie trendów epidemiologicznych, a także wspiera planowanie zasobów i polityk zdrowotnych. W kontekście globalnym, WHO koordynuje działania nadzorcze, a systemy takie jak NNDSS czy EWRS umożliwiają wymianę informacji i koordynację reakcji na transgraniczne zagrożenia zdrowotne.

Zrozumienie epidemiologii chorób zakaźnych
Epidemiologia chorób zakaźnych to dziedzina nauki zajmująca się badaniem, w jaki sposób i dlaczego choroby zakaźne pojawiają się i rozprzestrzeniają wśród różnych populacji, oraz jakie strategie mogą zapobiegać lub ograniczać rozprzestrzenianie się chorób na poziomie populacyjnym1. Jest to kluczowy element zdrowia publicznego, który pozwala na śledzenie, monitorowanie i kontrolowanie chorób, które mogą mieć lokalny, krajowy lub globalny wpływ2. Choroby zakaźne, od grypy po ospę, dotykają nas wszystkich w pewnym momencie życia i stanowią jedno z najpoważniejszych zagrożeń dla zdrowia ludności na całym świecie34.
Pomimo pewnych przewidywań z przeszłości, choroby zakaźne pozostają główną przyczyną zgonów na świecie5. Stały globalny wpływ epidemii HIV/AIDS, malarii i gruźlicy, pojawianie się wcześniej nierozpoznanych patogenów oraz zagrożenie ze strony opornych patogenów zwróciły uwagę na potrzebę posiadania specjalistów zdrowia publicznego dobrze wyszkolonych w kwestiach chorób zakaźnych6. Region Zachodniego Pacyfiku, będący najbardziej zróżnicowanym regionem na świecie, boryka się z wyjątkowymi wyzwaniami zdrowia publicznego i jest uważany za miejsce występowania ognisk oraz nowych i ponownie pojawiających się chorób zakaźnych, takich jak SARS, MERS, ptasia grypa, Zika i denga7.
Zakres i znaczenie epidemiologii chorób zakaźnych
Epidemiologia chorób zakaźnych obejmuje szeroki zakres działań badawczych – od poszukiwania nowych patogenów przy użyciu zaawansowanych technik molekularnych po długoterminowe badania populacyjne mające na celu określenie dynamiki transmisji i spektrum chorób8. Wymaga ona wykorzystania tradycyjnych metod epidemiologicznych, a także metod, których nie można zastosować do chorób niezakaźnych, takich jak modelowanie matematyczne9.
Koncentracja jest szeroka, począwszy od biologii i biologii molekularnej interakcji patogen-gospodarz, poprzez odpowiedź immunologiczną gospodarza na zakażenie związaną z ochroną lub patologią, ekologię, ewolucję i przenoszenie czynników zakaźnych, aż po metody nadzoru laboratoryjnego i epidemiologię chorób zakaźnych10. Pojawiające się metody molekularne są kluczowe dla przyszłych wysiłków badawczych nad epidemiologią chorób zakaźnych11.
Systemy nadzoru chorób zakaźnych
Nadzór nad chorobami zakaźnymi to epidemiologiczna praktyka, dzięki której monitorowane jest rozprzestrzenianie się chorób w celu ustalenia wzorców progresji12. Jest to ciągłe, systematyczne zbieranie, analiza i interpretacja danych związanych ze zdrowiem w celu podejmowania działań1314. Nadzór jest podstawą, na której opiera się wiele sukcesów zdrowia publicznego, którymi cieszymy się dzisiaj15.
Cele i funkcje nadzoru chorób zakaźnych
Cele nadzoru nad chorobami zakaźnymi są trojakie:
- Opisanie obecnego obciążenia i epidemiologii choroby
- Monitorowanie trendów
- Identyfikacja ognisk i nowych patogenów16
Nadzór monitoruje również kontrolę, eliminację i eradykację chorób17. Kluczowym aspektem nadzoru nad chorobami zakaźnymi jest cykl wykrywania, reagowania i zapobiegania ognisk choroby18. Dane z nadzoru nad chorobami:
- Służą jako system wczesnego ostrzegania przed zbliżającymi się ogniskami, które mogą stać się zagrożeniem dla zdrowia publicznego
- Umożliwiają monitorowanie i ocenę wpływu interwencji
- Pomagają śledzić postępy w kierunku określonych celów
- Monitorują i wyjaśniają epidemiologię problemów zdrowotnych, kierując ustalaniem priorytetów oraz planowaniem i oceną polityki i strategii zdrowia publicznego19
Skuteczny nadzór może poprawić wykrywanie ognisk chorób w sytuacjach awaryjnych, takich jak konflikty w krajach lub po klęskach żywiołowych20. Nadzór nad chorobami jest sednem systemu zdrowia publicznego. Jest używany do monitorowania trendów chorób w czasie, wykrywania ognisk chorób i zwiększania naszej wiedzy o czynnikach ryzyka, które przyczyniają się do rozwoju chorób21.
Rodzaje systemów nadzoru
Nadzór nad chorobami zakaźnymi może mieć różne podejścia w zależności od epidemiologii i prezentacji klinicznej choroby oraz celów nadzoru22. Główne typy obejmują:
Nadzór bierny: Opiera się na regularnym zgłaszaniu chorób przez pracowników ochrony zdrowia i placówki. Nadzór nad chorobami podlegającymi zgłoszeniu jest przykładem nadzoru biernego23. Nadzór bierny prawdopodobnie pomija przypadki ze względu na strukturę raportowania24.
Nadzór aktywny: Ma na celu wykrycie każdego przypadku25. Nadzór nad niektórymi chorobami może być mieszanką nadzoru biernego i aktywnego, w którym nadzór bierny jest uzupełniany przez nadzór aktywny w celu zbadania sygnałów ogniska wykrytych poprzez nadzór bierny26.
Nadzór oparty na społeczności: Jest przydatny do badania chorób docelowych do eradykacji, ponieważ wszystkie przypadki muszą być śledzone i nie ogranicza się do przypadków wystarczająco poważnych, aby zostać przyjętym do szpitala, lub tych, które mają dostęp do placówki opieki zdrowotnej27. Nadzór prowadzony przez społeczność (CBS) jest definiowany przez WHO jako systematyczne wykrywanie i zgłaszanie zdarzeń o znaczeniu dla zdrowia publicznego w społeczności przez członków społeczności28.
Seronadzór: Obejmuje wykorzystanie próbek krwi do określenia obciążenia chorobą lub luk w odporności w populacji29.
Nadzór nad niepożądanymi odczynami poszczepiennymi (AEFI): Jest kluczowym elementem zapewnienia bezpieczeństwa szczepionek w populacjach, w których są one stosowane30.
Nadzór ścieków: Epidemiologia oparta na ściekach (WBE) to podejście makroepidemiologiczne, którego celem jest zapewnienie kompleksowej oceny narażenia populacji na czynniki zakaźne oraz zanieczyszczenia biologiczne i chemiczne poprzez analizę ścieków31. Podczas pandemii COVID-19 nastąpiło szerokie wdrożenie nadzoru ścieków w społecznościach na terenie Stanów Zjednoczonych, aby pomóc śledzić rozprzestrzenianie się choroby32.
Nadzór przypadków i zgłaszanie chorób
Nadzór przypadków odbywa się za każdym razem, gdy agencje zdrowia publicznego na poziomie lokalnym, stanowym lub krajowym zbierają informacje o przypadku lub osobie zdiagnozowanej z chorobą lub stanem, który stanowi poważne zagrożenie dla zdrowia Amerykanów33. Kluczową częścią nowoczesnego nadzoru nad chorobami jest praktyka zgłaszania przypadków chorób34.
Formalne zgłaszanie chorób zakaźnych podlegających obowiązkowi zgłaszania jest wymogiem nałożonym na świadczeniodawców opieki zdrowotnej przez wiele rządów regionalnych i krajowych oraz na rządy krajowe przez Światową Organizację Zdrowia w celu monitorowania rozprzestrzeniania się chorób w wyniku przenoszenia czynników zakaźnych35. Od 1969 roku WHO wymaga, aby wszystkie przypadki następujących chorób były zgłaszane do organizacji: cholera, dżuma, żółta febra, ospa, gorączka nawrotowa i tyfus36.
Krajowy System Nadzoru Chorób Podlegających Zgłoszeniu (NNDSS) otrzymuje i udostępnia dane dotyczące przypadków z departamentów zdrowia stanowych, lokalnych i terytorialnych, aby pomóc zdrowiu publicznemu monitorować, kontrolować i zapobiegać poważnym chorobom37. CDC monitoruje około 120 tych chorób i stanów podlegających zgłoszeniu na poziomie krajowym38.
Nadzór przypadków jest podstawą praktyki zdrowia publicznego39. Zgodnie ze standardowymi definicjami przypadków, nadzór przypadków zbiera informacje, które urzędnicy zdrowia publicznego mogą wykorzystać do zrozumienia, gdzie występują choroby, jak można im zapobiegać i które grupy są najbardziej dotknięte40.
Znaczenie nadzoru chorób zakaźnych
Nadzór jest niewątpliwie istotnym, wręcz kluczowym składnikiem każdego programu kontroli chorób41. Jest stosowany do nakreślenia obrazu postępu i ogólnego obciążenia infekcją lub chorobą, aby można było mierzyć każde działanie zapobiegawcze lub terapeutyczne w miarę jego postępu42. Nadzór nad chorobami zakaźnymi jest narzędziem epidemiologicznym służącym do monitorowania obciążenia chorobami i epidemiologii chorób oraz identyfikacji ognisk i nowych patogenów43.
Korzyści z nadzoru chorób zakaźnych
Skuteczny system nadzoru chorób jest niezbędny do szybkiego wykrywania ognisk chorób, zanim się rozprzestrzenią, kosztują życie i staną się trudne do kontrolowania44. Nadzór jest zorientowanym na działanie narzędziem zdrowia publicznego45. Informacje z nadzoru mogą być wykorzystywane na poziomie globalnym, regionalnym, krajowym, lokalnym i indywidualnym46.
Kluczowe korzyści płynące z nadzoru chorób zakaźnych obejmują:
- Identyfikację przypadków do zbadania i dalszych działań
- Oszacowanie wielkości problemu zdrowotnego i śledzenie trendów w jego występowaniu i dystrybucji
- Formułowanie i ocenę środków kontroli i zapobiegania
- Wykrywanie ognisk lub epidemii i generowanie odpowiednich interwencji
- Monitorowanie zmian w czynnikach zakaźnych (np. oporność na antybiotyki, pojawiające się infekcje)
- Ułatwianie badań epidemiologicznych i laboratoryjnych
- Wykrywanie zmian w praktyce zdrowotnej (np. wpływ stosowania nowych metod diagnostycznych na liczbę przypadków)
- Ułatwianie planowania (np. alokacja zasobów programu, rozwój polityki)47
Miejsca nadzoru mogą być również wykorzystywane jako platformy do badań i specjalnych studiów48.
Charakterystyka skutecznych systemów nadzoru
Skuteczny nadzór nad chorobami zakaźnymi wymaga, aby dane były reprezentatywne, terminowe i spójne49. Zbieranie danych musi być systematyczne. Analiza danych powinna obejmować analizę według czasu, miejsca i osoby50.
Systemy nadzoru powinny być w stanie:
- Namalować obraz obciążenia zdrowotnego i trendów w społeczności
- Zapewnić wczesne wykrywanie ognisk chorób
- Monitorować interwencje zdrowotne
- Zapewnić dokładne i terminowe informacje dla decydentów
- Wspierać planowanie zasobów zdrowotnych51
Terminowość jest ważnym składnikiem systemu nadzoru. Jest to szczególnie ważne w przypadku wczesnego rozpoznania ognisk, ale także przy ocenie powodzenia lub niepowodzenia programów kontroli rozprzestrzeniania się infekcji, np. wpływu lockdownu na COVID-19 na populację52.
Reprezentatywność to kolejny ważny składnik programu nadzoru. Program musi być reprezentatywny dla wpływu tej infekcji na populację53. Systemy nadzoru powinny być regularnie oceniane pod kątem użyteczności, a także dokładności, wydajności i skuteczności54.
Wyzwania i innowacje w nadzorze chorób zakaźnych
Łatwość i szybkość współczesnych podróży, dystrybucja towarów (zwłaszcza produktów spożywczych) w coraz szerszych częściach świata oraz niekontrolowane rozprzestrzenianie się ptaków i innych dzikich zwierząt przez granice sprawiły, że globalny i międzynarodowy nadzór stał się niezbędny dla kontroli ognisk i infekcji55.
Wyzwania w nadzorze chorób zakaźnych
Światowa Organizacja Zdrowia (WHO) jest wiodącą agencją w zakresie koordynacji globalnej reakcji na główne choroby56. Jednak nadzór nad H5N1 u ludzi, drobiu, dzikich ptaków, kotów i innych zwierząt pozostaje bardzo słaby w wielu częściach Azji i Afryki. Wiele pozostaje nieznane na temat dokładnego zakresu jego rozprzestrzeniania się57.
Populacje dotknięte sytuacjami kryzysowymi są stale narażone na ryzyko wystąpienia chorób epidemicznych i innych zagrożeń dla zdrowia publicznego58. Epidemie chorób zakaźnych występują częściej, rozprzestrzeniają się szybciej i dalej niż kiedykolwiek wcześniej, w wielu różnych regionach świata59.
Sytuacje humanitarne zwiększają ryzyko przenoszenia chorób zakaźnych i innych stanów zdrowotnych, takich jak ciężkie niedożywienie60. W naszym zglobalizowanym świecie choroby mogą rozprzestrzeniać się bardzo szybko z jednego kraju do drugiego. Wczesne wykrywanie zagrożeń dla zdrowia wymaga ciągłego solidnego nadzoru i mechanizmów wczesnego ostrzegania i reakcji61.
Wykorzystanie technologii i innowacji
Technologia zwiększa dostępność danych dotyczących zdrowia, które mogą być wykorzystane do nadzoru nad chorobami zakaźnymi, w tym źródeł wykraczających poza tradycyjne systemy nadzoru biernego lub aktywnego62. W naszym zglobalizowanym świecie choroby mogą rozprzestrzeniać się bardzo szybko z jednego kraju do drugiego63.
Ostatnia dekada przyniosła znaczne postępy i rozwój nadzoru nad chorobami zakaźnymi opartego na internecie dzięki zaawansowanym możliwościom obliczeniowym, rosnącemu przyjęciu inteligentnych urządzeń, zwiększonej dostępności sztucznej inteligencji (AI), a także presji środowiskowej, w tym zmianom klimatu i użytkowania gruntów, które przyczyniają się do zwiększonego zagrożenia i rozprzestrzeniania się pandemii i pojawiających się chorób zakaźnych64.
Wraz z rosnącym obciążeniem chorobami zakaźnymi i pandemią COVID-19, potrzeba opracowania nowych technologii i integracji podejść opartych na danych internetowych w celu poprawy nadzoru nad chorobami zakaźnymi jest większa niż kiedykolwiek65.
Systemy nadzoru oparte na internecie lub cyfrowe wykorzystują źródła danych online do wykrywania sygnałów cyfrowych dla potencjalnych wskaźników lub wczesnych oznak ognisk chorób zakaźnych w oparciu o poszukiwanie informacji online i trendy w zachowaniach użytkowników z różnych mediów społecznościowych i źródeł wyszukiwarek66.
Analizując duże ilości danych online w czasie rzeczywistym, modele predykcyjne mogą być wykorzystywane do identyfikacji klastrów wysokiego ryzyka, trendów i wczesnych sygnałów ostrzegawczych, często poprzedzających tradycyjne metody nadzoru dla wykrywania chorób i mogą zapewnić wczesne ostrzeżenie o ogniskach przed tymi alertami systemu opieki zdrowotnej67.
Globalne inicjatywy nadzoru chorób zakaźnych
Program monitorowania pojawiających się chorób ProMED to internetowy system raportowania poświęcony szybkiemu globalnemu rozpowszechnianiu informacji o ogniskach chorób zakaźnych i ostrym narażeniu na toksyny, które wpływają na zdrowie ludzi, w tym na choroby u zwierząt i roślin uprawianych na żywność lub paszę dla zwierząt68. Dostarczając wczesnego ostrzeżenia o wybuchach nowych i pojawiających się ponownie chorób, środki ostrożności w zakresie zdrowia publicznego na wszystkich poziomach mogą być podejmowane w odpowiednim czasie, aby zapobiec przenoszeniu epidemii i ratować życie69.
Rola organizacji międzynarodowych w nadzorze
Światowa Organizacja Zdrowia (WHO) jest wiodącą agencją w zakresie koordynacji globalnej reakcji na główne choroby70. Program WHO Epidemic and Pandemic Alert and Response (EPR) służący do szybkiego wykrywania, weryfikacji i odpowiedniego reagowania na choroby podatne na epidemie i nowe zagrożenia chorobami71.
Skoordynowane przez WHO International Outbreak Alert and Response ma na celu zapewnienie, że „ogniska o potencjalnym znaczeniu międzynarodowym są szybko weryfikowane, a informacje są szybko udostępniane w Sieci”, ale niekoniecznie publicznie; integrację i koordynację „działań wspierających wysiłki krajowe”, a nie kwestionowanie władz krajowych w tym kraju, aby „szanować niezależność i obiektywizm wszystkich partnerów”72.
Decyzja nr 2119/98/WE Parlamentu Europejskiego i Rady pierwotnie ustanowiła sieć nadzoru epidemiologicznego i kontroli chorób zakaźnych73. Ta nowa decyzja ożywiła sieć nadzoru epidemiologicznego nad chorobami zakaźnymi i powiązanymi specjalnymi kwestiami zdrowotnymi74. Utrzymuje i dalej wzmacnia europejską sieć nadzoru epidemiologicznego, która nadal jest obsługiwana i koordynowana przez ECDC75.
Międzynarodowe standardy i ramy prawne
Nowe Międzynarodowe Przepisy Zdrowotne (IHR) wymagają od państw członkowskich Światowej Organizacji Zdrowia (WHO) oceny ich podstawowych zdolności w zakresie nadzoru76. Około 50 chorób i specjalnych kwestii zdrowotnych, takich jak oporność na środki przeciwdrobnoustrojowe, jest monitorowanych przez sieć nadzoru epidemiologicznego UE: od wąglika po zikę77.
Rozporządzenie (UE) 2022/2371 daje Komisji uprawnienia do aktualizacji listy chorób zakaźnych i istotnych kwestii zdrowotnych, takich jak oporność na środki przeciwdrobnoustrojowe, w celu zapewnienia ich objęcia siecią nadzoru epidemiologicznego78. Komisja ustala również definicje przypadków dotyczące każdej choroby zakaźnej, które państwa członkowskie stosują do nadzoru i raportowania do ECDC, zapewniając w ten sposób porównywalność i kompatybilność zbieranych danych na poziomie Unii79.
System EWRS został z powodzeniem wykorzystany do alertowania, wymiany informacji i koordynacji środków w odpowiedzi na transgraniczne zdarzenia chorób zakaźnych, przy obecnych i poprzednich zarządzanych wybuchach, takich jak COVID-19, małpia ospa, pandemia grypy A(H1N1), Ebola itp.80 EWRS powinien dodatkowo umożliwiać wymianę środków zdrowia publicznego, ocen ryzyka i funkcji zarządzania kryzysowego, takich jak te wymagające wymiany danych dotyczących zdrowia osobistego, dla efektywnego cyfrowego transgranicznego śledzenia kontaktów i ewakuacji medycznej81.
Nadzór chorób zakaźnych w praktyce
Skuteczny nadzór nad chorobami zakaźnymi u ludzi zaczyna się od świadczeniodawcy opieki zdrowotnej82. To na pracownikach służby zdrowia, przy pomocy publicznych i prywatnych laboratoriów, spoczywa odpowiedzialność za diagnozowanie i zgłaszanie przypadków chorób zakaźnych podlegających zgłoszeniu83.
Struktury i procesy nadzoru
Państwowe przepisy lub regulacje zobowiązują świadczeniodawców opieki zdrowotnej i laboratoria do zgłaszania potwierdzonych lub prawdopodobnych przypadków chorób zakaźnych podlegających zgłoszeniu do lokalnego lub stanowego departamentu zdrowia lub do obu84. Zatem nadzór to informacja do działania85.
Jednostka Nadzoru Epidemiologicznego i Chorób otrzymuje zgłoszenia przypadków i zbiera dodatkowe szczegółowe informacje poprzez dochodzenie w sprawie przypadków. Raporty te pomagają pracownikom zdrowia publicznego zrozumieć występowanie chorób w społeczności i kierować odpowiednimi strategiami zapobiegania lub środkami ochronnymi, aby zmniejszyć rozprzestrzenianie się chorób w społeczności86.
Departament Zdrowia Okręgu Columbia (DC Health) opiera się na różnych partnerach, w tym personelu placówek opieki zdrowotnej, pielęgniarkach szkolnych i personelu laboratoryjnym, aby dostarczać nam informacji o chorobach, które mogą rozprzestrzeniać się w społeczności lub budzą obawy dotyczące zdrowia publicznego87. Informacje te są wykorzystywane do monitorowania zdrowia mieszkańców Dystryktu, identyfikowania i badania potencjalnych ognisk, oceny skuteczności interwencji zdrowia publicznego oraz wkładu w dane nadzoru krajowego zbierane przez Centra Kontroli i Zapobiegania Chorobom (CDC)88.
Praktyczne przykłady nadzoru chorób zakaźnych
Departament Epidemiologii Chorób Zakaźnych prowadzi nadzór nad zdrowiem publicznym oraz monitorowanie i zapobieganie chorobom zakaźnym na całym świecie89. Tradycyjny nadzór i badania, badania kontroli przypadków i badania kohortowe będą niezbędne do określenia roli takich patogenów w przyczynowości chorób90.
Jednostka epidemiologii chorób zakaźnych obejmuje krajową i globalną pracę nad epidemiologią nowych i ponownie pojawiających się infekcji, globalnymi zagrożeniami chorobami zakaźnymi, nadzorem nad chorobami, wykrywaniem chorób, opracowywaniem szczepionek i innych metod zapobiegania, opcjami leczenia, nauką wdrożeniową oraz rolą patogenów zakaźnych w patogenezie przewlekłych chorób niezakaźnych (takich jak rak i choroby układu krążenia)91.
PREDICT, duży program finansowany przez Program Zagrożeń Pandemicznych Agencji Rozwoju Międzynarodowego Stanów Zjednoczonych, opracowuje globalny system ostrzegania o nowo pojawiających się chorobach oraz przewidywania i oceny pojawiających się chorób zakaźnych, które przemieszczają się między zwierzętami a ludźmi, aby zapobiec następnej globalnej pandemii92.
W New Hampshire, Sekcja Nadzoru Chorób Zakaźnych (IDSS) zarządza kilkoma systemami nadzoru (danych), aby obserwować objawy i grupy objawów, które mogą być wczesnymi sygnałami ostrzegawczymi dla pojawiających się chorób zakaźnych, bioterroryzmu lub problemów związanych z toksynami. Jest to nazywane nadzorem syndromicznym93.
Automatyczny Nadzór Danych z Oddziałów Ratunkowych Szpitali (AHEDD) zbiera dane w czasie rzeczywistym ze wszystkich 26 oddziałów ratunkowych szpitali opieki doraźnej w NH94. Ten system CDC jest najczęściej używanym środkiem do monitorowania infekcji związanych z opieką zdrowotną95.
| Typ nadzoru | Główne cechy | Zastosowania |
|---|---|---|
| Nadzór bierny | Opiera się na regularnym zgłaszaniu chorób przez pracowników ochrony zdrowia | Monitorowanie trendów chorób, identyfikacja ognisk |
| Nadzór aktywny | Proaktywne poszukiwanie przypadków | Wykrywanie wszystkich przypadków w populacji |
| Nadzór oparty na społeczności | Angażuje członków społeczności w działania nadzoru | Choroby docelowe do eradykacji, obszary o ograniczonym dostępie do opieki zdrowotnej |
| Seronadzór | Wykorzystuje próbki krwi do wykrywania przeciwciał | Określenie obciążenia chorobą lub luk w odporności |
| Nadzór ścieków | Analiza ścieków komunalnych | Wczesne wykrywanie patogenów, monitorowanie trendów chorób |
| Nadzór syndromiczny | Monitorowanie objawów i grup objawów | Wczesne wykrywanie chorób zakaźnych, bioterroryzmu |
| Nadzór cyfrowy | Wykorzystuje dane online i media społecznościowe | Wykrywanie ognisk przed tradycyjnymi metodami nadzoru |
| Nadzór genomiczny | Sekwencjonowanie genomu patogenów | Śledzenie transmisji patogenów, identyfikacja wariantów |
Przyszłość nadzoru chorób zakaźnych
Ostatnia dekada przyniosła wiele zmian w ekosystemie online, z pojawiającymi się platformami mediów społecznościowych, zmieniającymi się zachowaniami użytkowników oraz pojawieniem się chatbotów AI zintegrowanych z wyszukiwarkami i mediami społecznościowymi, zacierając granice między źródłami informacji96.
Nowe technologie i podejścia
Nadzór cyfrowy doskonale wykrywa wczesne sygnały od niedawno narażonych osób, osób z łagodniejszymi stanami chorobowymi i młodszych grup demograficznych z ograniczonym dostępem do regularnej opieki zdrowotnej lub mniejszą skłonnością do poszukiwania opieki97.
Dane cyfrowe zapewniają dostępność w czasie zbliżonym do rzeczywistego, ułatwiają dyskusje na temat objawów lub słów kluczowych z funkcjonalnością geotagowania oraz łączą zachowania online z unikalnymi kontami użytkowników i sieciami online, potencjalnie odzwierciedlając połączenia ze świata rzeczywistego, takie jak rodzina, przyjaciele i współpracownicy98.
Opracowanie zintegrowanych wieloźródłowych EWS ma znaczny potencjał dla poprawy wczesnego wykrywania sygnałów chorobowych i identyfikacji pojawiających się ognisk, szczególnie w przypadku chorób przenoszonych przez wektory lub chorób układu oddechowego wrażliwych na klimat i pogodę99.
Przyszłe kierunki i wyzwania
Dane cyfrowe do nadzoru nad chorobami zakaźnymi pozostają ważnym obszarem badań100. Pandemia COVID-19 spowodowała znaczne zakłócenia w globalnym zdrowiu, z szeroko rozpowszechnionym wpływem na istniejące środki zdrowia publicznego, programy szczepień i zapobiegania oraz programy nadzoru społecznego dla wielu chorób101.
W miarę zbierania i udostępniania takich danych należy jednak brać pod uwagę prywatność osób102. Aby podkreślić badania cyfrowe i obliczeniowe istotne dla nadzoru i kontroli epidemiologicznej, zebrano Kolekcję, która będzie regularnie aktualizowana103.
Podkreślają one potrzebę zmiany rutynowego zbierania danych społeczno-demograficznych w celu zwiększenia ziarnistości przestrzennej i czasowej, aby budować możliwe do działania modele, które mogą być wykorzystane do wdrażania skutecznych polityk powstrzymywania104.
Jest to kluczowa kwestia, którą poruszono w zamówionej Perspektywie, która opracowuje możliwe ramy wykorzystania cyfrowo zbieranych danych (tj. danych z śledzenia telefonów komórkowych) do nadzoru epidemiologicznego105. Niemniej jednak pozostają obawy dotyczące potencjalnych nierówności wynikających z ram opartych na technologii106.
W miarę jak dane zbierane cyfrowo stają się coraz bardziej powszechne w nadzorze nad chorobami zakaźnymi, w pełni rozpoznajemy wyzwania związane z zapewnieniem dostępności danych przy jednoczesnym ochronie prywatności osobistej zebranych danych107.

- #1 Infectious Disease Epidemiology – Public Healthhttps://publichealth.cornell.edu/curriculum/concentrations/infectious-disease-epidemiology/
Infectious disease epidemiology is the study of how and why infectious diseases emerge and spread among different populations, and what strategies can prevent or contain the spread of disease at the population level. […] Our MPH Program prepares students in the Infectious Disease Epidemiology concentration to address both established and emerging infectious diseases that have local, national, and global impact on public health. […] Core to this practice is the ability to assess and monitor population health; investigate, diagnose, and address health hazards and root causes; communicate effectively to inform and educate; and enable equitable access to prevention and care services. […] Graduates of the Infectious Disease Epidemiology concentration build careers as epidemiologists, biostatisticians, consultants, analysts, project managers, and more.
- #2 Infectious Disease Epidemiology Research Unit | Columbia Public Health | Columbia University Mailman School of Public Healthhttps://www.publichealth.columbia.edu/academics/departments/epidemiology/research/infectious-disease-epidemiology
Infectious diseases continue to have a substantial impact on the health of communities around the world. […] Emerging molecular methods are critical for future efforts researching the epidemiology of infectious diseases. […] Traditional surveillance and surveys, case control and cohort studies will be necessary to define the role of such pathogens in disease causality. […] The infectious disease epidemiology unit encompasses domestic and global work on the epidemiology of emerging and re-emerging infections, global infectious disease threats, disease surveillance, disease detection, development of vaccines and other prevention methods, treatment options, implementation science, and the role of infectious pathogens in the pathogenesis of chronic non-communicable diseases (such as cancer and cardiovascular disease).

- #5 Infectious Disease Epidemiology Certificate | Columbia Public Health | Columbia University Mailman School of Public Healthhttps://www.publichealth.columbia.edu/academics/degrees/master-public-health/certificates/infectious-disease-epidemiology
Despite some predictions, infectious diseases remain the leading causes of death worldwide. […] The continuing global impact of the HIV/AIDS, malaria, and tuberculosis epidemics; the emergence of previously unrecognized pathogens; and the threat of resistant pathogens have all focused attention on the need for public health professionals well trained in infectious disease issues.

Nearly 80 percent of U.S. households are connected to municipal wastewater collection systems. These sewer systems contain the biological waste, including discharged pathogens, of the human populations they serve. During the COVID-19 pandemic, wastewater surveillance studies successfully tracked the virus shed in feces and provided advanced indications of outbreaks, sometimes weeks ahead of other public health data. This study will examine the value of wastewater surveillance as a tool to trace, prevent, and control the spread of infectious diseases beyond COVID-19. […] The COVID-19 pandemic sparked widespread implementation of wastewater surveillance in communities across the United States to help track the spread of the disease. In contrast to clinical laboratory testing that tracks individual cases of infection, wastewater surveillance provides a way to measure the amount of DNA from pathogens coming from homes, businesses, and other institutions that share a sewer system.

Surveillance is the backbone of any disease control program. Data must be representative, timely, and consistent. Collection of data must be systematic. Analysis of data should include analysis by time, place, and person. Surveillance is undoubtedly an essential indeed critical ingredient of any disease control program. It is used to paint a picture of the progress and overall burden of infection or disease, so that any preventive or therapeutic action can be measured as it advances. Surveillance is the ongoing and systematic collection of routine data which are then analyzed, interpreted, and acted upon. Surveillance is essential for evaluating the impact of an intervention, such as mass vaccination, on a population. It can also act as a fairly sensitive system for the early detection of outbreaks. Timeliness is another important ingredient of a surveillance system. This is especially the case with infection. It is particularly essential for the early recognition of outbreaks, but it is important also in evaluating the success or otherwise of programs to control the spread of an infection e.g., the effect of lockdown on coronavirus disease (COVID-19) on a population. Representativeness is another important ingredient of a surveillance program. The program has to be representative of the effect of that infection on a population. Surveillance of outbreaks (as opposed to individual infections) can be revealing, and important to allow public health measures. Surveillance systems should ideally be frequently evaluated for usefulness, as well as for accuracy, efficiency, and effectiveness. The ease and speed of modern travel, the distribution of goods (especially foodstuffs) across increasingly wide parts of the world, and the uncontrollable spread of birds and other wildlife across boundaries has made global and international surveillance essential for outbreak and infection control.

Infectious disease surveillance is the ongoing collection, analysis, interpretation, and dissemination of health data. This type of assessment is a core public health function. Communicable disease surveillance monitors patterns of disease occurrence and assesses the health status of South Dakota’s population. Surveillance can detect sudden changes in disease occurrence, such as an outbreak, or identify long-term disease trends or new and emerging diseases. Surveillance activities are linked to public health actions, such as investigation, control and prevention, evaluation, or planning and allocating resources to address the diseases affecting the population. […] An important component of surveillance is sharing data back with health care providers, public health agencies, policymakers, and the general population. The surveillance cycle is not complete until disease information is relayed to those who have responsibilities for the various public health and medical actions. Surveillance assessment reports should serve to inform and motivate. Infectious disease surveillance endeavors to: identify cases for investigation and follow-up, estimate the magnitude of a health problem and follow trends in its incidence and distribution, formulate and evaluate control and prevention measures, detect outbreaks or epidemics and generate appropriate interventions, monitor changes in infectious agents (e.g., antibiotic resistance, emerging infections), facilitate epidemiologic and laboratory research, detect changes in health practice (e.g., impact of use of new diagnostic methods on case counts), facilitate planning (e.g., allocation of program resources, policy development).

Surveillance is the backbone of any disease control program. Data must be representative, timely, and consistent. Collection of data must be systematic. Analysis of data should include analysis by time, place, and person. Surveillance is undoubtedly an essential indeed critical ingredient of any disease control program. It is used to paint a picture of the progress and overall burden of infection or disease, so that any preventive or therapeutic action can be measured as it advances. Surveillance is the ongoing and systematic collection of routine data which are then analyzed, interpreted, and acted upon. Surveillance is essential for evaluating the impact of an intervention, such as mass vaccination, on a population. It can also act as a fairly sensitive system for the early detection of outbreaks. Timeliness is another important ingredient of a surveillance system. This is especially the case with infection. It is particularly essential for the early recognition of outbreaks, but it is important also in evaluating the success or otherwise of programs to control the spread of an infection e.g., the effect of lockdown on coronavirus disease (COVID-19) on a population. Representativeness is another important ingredient of a surveillance program. The program has to be representative of the effect of that infection on a population. Surveillance of outbreaks (as opposed to individual infections) can be revealing, and important to allow public health measures. Surveillance systems should ideally be frequently evaluated for usefulness, as well as for accuracy, efficiency, and effectiveness. The ease and speed of modern travel, the distribution of goods (especially foodstuffs) across increasingly wide parts of the world, and the uncontrollable spread of birds and other wildlife across boundaries has made global and international surveillance essential for outbreak and infection control.

The new International Health Regulations (IHR) require World Health Organization (WHO) member states to assess their core capacity for surveillance. […] Reviewing surveillance systems for infectious diseases also has the potential to identify worthwhile improvements to the organisation of such systems at a country-level. […] We describe in this article a review of these systems and use the term surveillance sector review as this work seeks to identify and examine all of the important surveillance activities across a defined area of disease burden. […] A surveillance sector review builds upon concepts of more integrated surveillance promoted by the WHO, notably for linking surveillance and action. […] In this article we aim to: (i) Present a framework for describing and categorising diverse surveillance systems and illustrate this by applying it to all of the surveillance systems operating for one disease sector in a single developed country (in this case infectious diseases in New Zealand); (ii) Present an approach for systematically reviewing the public health surveillance systems operating across a broad public health sector (a surveillance sector review); and (iii) Discuss preliminary findings from this review to illustrate its use for identifying potential surveillance sector gaps that require assessment in later stages of the surveillance sector review.

EWRS should further allow the exchange of public health measures, risk assessments and crisis management functionalities, such as those requiring the exchange of personal health data, for effective digital cross-border contact tracing and medical evacuation. […] The alerts are posted no later than 24 hours from when the EU country or the Commission first become aware of the threat. […] During the COVID-19 response, the EWRS has also supported the exchange of passenger locator forms data for cross-border contact tracing. Contact tracing is an essential tool for an effective response that allows possibly infected individuals to be rapidly identified to isolate, test, or treat them.

Surveillance is defined as the ongoing, systematic collection, analysis, and interpretation of outcome-specific data for use in the planning, implementation, and evaluation of public health practice. […] Surveillance is the foundation upon which many of the public health successes we enjoy today are based. […] Effective surveillance of disease in humans begins with the health care provider. […] It is the responsibility of health care personnel, with the help of public and private laboratories, to diagnose and report cases of notifiable infectious diseases. […] State legislation or regulations mandate that health care providers and laboratories report confirmed or probable cases of notifiable infectious diseases to their local or state health department, or both. […] Hence, surveillance is information for action.
