Choroba koronawirusowa 2019 (covid-19)
Zapobieganie i profilaktyka

COVID-19, wywoływane przez SARS-CoV-2, rozprzestrzenia się głównie drogą kropelkową, także od osób bezobjawowych. Podstawą profilaktyki jest wielopoziomowe podejście obejmujące szczepienia, które WHO i CDC zalecają od 6. miesiąca życia, szczególnie u osób z grup wysokiego ryzyka (osoby starsze, z chorobami współistniejącymi, kobiety w ciąży). Szczepienia znacząco redukują ryzyko ciężkiego przebiegu, hospitalizacji i zgonów. Dla pacjentów z umiarkowaną lub ciężką immunosupresją dostępna jest profilaktyka przedekspozycyjna (PrEP) z użyciem przeciwciała monoklonalnego Pemivibart (Pemgarda), zatwierdzonego przez FDA dla osób ≥12 lat i ≥40 kg. Inne leki, takie jak iwermektyna czy hydroksychlorochina, nie wykazały skuteczności i nie są rekomendowane.

Wprowadzenie do profilaktyki COVID-19

Choroba koronawirusowa 2019 (COVID-19) jest chorobą zakaźną wywoływaną przez wirus SARS-CoV-2, który rozprzestrzenia się głównie drogą kropelkową podczas kaszlu, kichania, mówienia czy oddychania. Wirus może być przenoszony nawet przez osoby bezobjawowe lub przed wystąpieniem objawów. Od początku pandemii opracowano liczne strategie zapobiegania zakażeniom oraz ograniczania rozprzestrzeniania się wirusa, które obejmują zarówno środki farmakologiczne, jak i niefarmakologiczne. Skuteczne zapobieganie COVID-19 wymaga zastosowania wielopoziomowego podejścia, obejmującego szczepienia, środki ochrony osobistej oraz zmiany zachowań społecznych123.

Szczepienia przeciwko COVID-19

Szczepienia przeciwko COVID-19 stanowią najskuteczniejszą metodę zapobiegania ciężkiemu przebiegowi choroby, hospitalizacji i zgonom związanym z COVID-19. Światowa Organizacja Zdrowia (WHO) oraz Centra Kontroli i Zapobiegania Chorobom (CDC) zalecają szczepienia wszystkim osobom w wieku 6 miesięcy i starszym12.

Szczepionki przeciwko COVID-19 są dostępne globalnie, a ich skuteczność w zapobieganiu ciężkiemu przebiegowi choroby została potwierdzona w licznych badaniach. Najlepszą ochronę zapewnia utrzymywanie aktualnego statusu szczepień zgodnie z zaleceniami odpowiednich organów zdrowia publicznego3.

Szczepienia są szczególnie ważne dla osób z grup wysokiego ryzyka, takich jak osoby starsze, osoby z chorobami współistniejącymi oraz kobiety w ciąży. Badania wskazują, że szczepienie w czasie ciąży może chronić nie tylko matkę, ale również noworodka przed zakażeniem i zmniejszać ryzyko hospitalizacji34.

Należy podkreślić, że szczepienia nie zastępują innych środków zapobiegawczych, ale stanowią podstawowy element kompleksowej strategii profilaktyki COVID-191.

Profilaktyka przedekspozycyjna

Dla osób z umiarkowaną lub ciężką immunosupresją dostępne są dodatkowe opcje profilaktyczne, które oferują dodatkową warstwę ochrony przed COVID-19. Profilaktyka przedekspozycyjna (pre-exposure prophylaxis, PrEP) polega na podaniu leków przed potencjalnym narażeniem na wirusa w celu zapobieżenia zakażeniu12.

Przeciwciała monoklonalne

Pemivibart (Pemgarda) to przeciwciało monoklonalne o szerokim spektrum działania i przedłużonym okresie półtrwania, wykazujące aktywność przeciwko SARS-CoV-2, w tym przeciwko nowszym wariantom wirusa. FDA zatwierdziło jego stosowanie u osób w wieku 12 lat i starszych, ważących co najmniej 40 kg, które są umiarkowanie lub ciężko immunosupresyjne134.

Warto zaznaczyć, że profilaktyka przedekspozycyjna nie zastępuje szczepień u osób kwalifikujących się do ich otrzymania, ale stanowi dodatkową opcję ochrony dla osób z osłabionym układem odpornościowym15.

Inne metody profilaktyki farmakologicznej

Badania nad innymi lekami stosowanymi w profilaktyce COVID-19, takimi jak iwermektyna, hydroksychlorochina czy lopinawir/rytonawir, nie dostarczyły przekonujących dowodów na zmniejszenie ryzyka zakażenia. WHO zdecydowanie odradza stosowanie hydroksychlorochiny w profilaktyce u osób niezakażonych COVID-19, opierając się na dowodach o wysokiej wiarygodności36.

Środki niefarmakologiczne w profilaktyce COVID-19

Higiena osobista

Podstawowe zasady higieny odgrywają kluczową rolę w zapobieganiu rozprzestrzeniania się COVID-191:

  • Regularne mycie rąk wodą z mydłem przez co najmniej 20 sekund lub używanie środków do dezynfekcji rąk zawierających co najmniej 60% alkoholu12
  • Zakrywanie ust i nosa zgiętym łokciem lub chusteczką podczas kaszlu lub kichania, a następnie natychmiastowe wyrzucenie zużytej chusteczki1
  • Unikanie dotykania oczu, nosa i ust nieumytymi rękami3
  • Regularne czyszczenie i dezynfekcja często dotykanych powierzchni, takich jak klamki, baterie i ekrany telefonów14

Dystans fizyczny i unikanie skupisk ludzi

Utrzymywanie dystansu fizycznego od innych osób jest ważnym elementem profilaktyki COVID-191:

  • Zachowanie odległości co najmniej 1 metra od innych osób, szczególnie tych, które kaszlą lub kichają12
  • Unikanie miejsc zatłoczonych, zamkniętych i wymagających bliskiego kontaktu (tzw. zasada 3C: closed spaces, crowded places, close-contact settings)3
  • Preferowanie spotkań na świeżym powietrzu zamiast w pomieszczeniach zamkniętych3
  • Stosowanie się do lokalnych wytycznych dotyczących ograniczeń zgromadzeń4

Stosowanie maseczek ochronnych

Noszenie dobrze dopasowanych maseczek może zmniejszyć rozprzestrzenianie się wirusa, szczególnie w sytuacjach, gdy utrzymanie dystansu fizycznego jest trudne lub niemożliwe12.

CDC zaleca noszenie maseczek w pomieszczeniach zamkniętych w obszarach o wysokiej liczbie osób hospitalizowanych z powodu COVID-19. Maseczka powinna dokładnie zakrywać nos, usta i brodę12.

WHO zaleca noszenie maseczek w społecznościach w sytuacjach podwyższonego ryzyka, niezależnie od lokalnej sytuacji epidemiologicznej3.

Wentylacja i poprawa jakości powietrza

Odpowiednia wentylacja pomieszczeń może zmniejszyć stężenie wirusa w powietrzu i ryzyko zakażenia12:

  • Otwieranie okien i drzwi w celu zwiększenia przepływu świeżego powietrza w pomieszczeniach23
  • Korzystanie z przenośnych oczyszczaczy powietrza z filtrami HEPA4
  • Preferowanie aktywności na świeżym powietrzu, szczególnie w przypadku spotkań z innymi osobami2

Postępowanie w przypadku podejrzenia zakażenia

W przypadku wystąpienia objawów COVID-19 lub kontaktu z osobą zakażoną, należy podjąć odpowiednie kroki w celu zapobieżenia dalszemu rozprzestrzenianiu się wirusa12:

  • Pozostanie w domu i samoizolacja w przypadku wystąpienia objawów COVID-1912
  • Wykonanie testu diagnostycznego w kierunku SARS-CoV-23
  • Skontaktowanie się z lekarzem lub odpowiednią infolinią w celu uzyskania porady4
  • Noszenie maseczki w przypadku konieczności kontaktu z innymi osobami5
  • Przestrzeganie okresu izolacji zgodnie z lokalnymi wytycznymi6

Profilaktyka COVID-19 w placówkach opieki zdrowotnej

Placówki opieki zdrowotnej wymagają szczególnych środków zapobiegawczych ze względu na zwiększone ryzyko transmisji wirusa12.

Środki ochrony osobistej dla personelu medycznego

Ryzyko zakażenia personelu medycznego można znacząco zmniejszyć poprzez stosowanie odpowiednich środków ochrony osobistej1:

  • Fartuchy ochronne
  • Rękawiczki
  • Maski N95 lub maski chirurgiczne
  • Ochrona oczu (gogle lub przyłbice)

Procedury zapobiegania i kontroli zakażeń

W placówkach opieki zdrowotnej należy wdrożyć standardowe środki zapobiegawcze oraz dodatkowe środki oparte na drodze transmisji (kontakt, kropelki, powietrze) podczas opieki nad pacjentami z podejrzeniem lub potwierdzonym COVID-191:

  • Ocena ryzyka
  • Higiena rąk
  • Higiena dróg oddechowych i etykieta kaszlu
  • Odpowiednie rozmieszczenie pacjentów
  • Techniki aseptyczne
  • Czyszczenie środowiska
  • Zarządzanie odpadami

Profilaktyka COVID-19 w miejscach publicznych i pracy

Miejsca publiczne i zakłady pracy wymagają wdrożenia środków zapobiegawczych w celu ograniczenia rozprzestrzeniania się wirusa12:

  • Regularne czyszczenie i dezynfekcja często dotykanych powierzchni1
  • Zapewnienie odpowiedniej wentylacji pomieszczeń2
  • Umożliwienie pracownikom zachowania dystansu fizycznego3
  • Zapewnienie środków do higieny rąk4
  • Umożliwienie pracy zdalnej, gdy jest to możliwe5
  • Ułatwienie pracownikom dostępu do szczepień6

Profilaktyka w grupach wysokiego ryzyka

Osoby z grup wysokiego ryzyka ciężkiego przebiegu COVID-19 powinny stosować dodatkowe środki ostrożności12:

  • Ścisłe przestrzeganie wszystkich podstawowych środków zapobiegawczych
  • Unikanie dużych zgromadzeń i zatłoczonych miejsc
  • Rozważenie noszenia maseczki nawet w sytuacjach, gdy nie jest to powszechnie wymagane
  • Szczególna dbałość o aktualny status szczepień
  • Rozważenie profilaktyki przedekspozycyjnej, jeśli pacjent się do niej kwalifikuje

Podsumowanie rekomendacji profilaktycznych

Skuteczna profilaktyka COVID-19 wymaga wielopoziomowego podejścia, obejmującego123:

  • Szczepienia jako podstawową metodę zapobiegania ciężkiemu przebiegowi choroby
  • Przestrzeganie zasad higieny osobistej
  • Zachowanie dystansu fizycznego
  • Noszenie maseczek w odpowiednich sytuacjach
  • Dbałość o odpowiednią wentylację pomieszczeń
  • Pozostawanie w domu w przypadku choroby
  • Testowanie w kierunku COVID-19 w przypadku objawów lub kontaktu z osobą zakażoną
  • Profilaktykę przedekspozycyjną dla osób kwalifikujących się do tego typu terapii

Wdrożenie tych środków zapobiegawczych może znacząco zmniejszyć ryzyko zakażenia SARS-CoV-2 i ciężkiego przebiegu COVID-19, przyczyniając się do ochrony zdrowia publicznego4.

    Frequently touched objects and surfaces should be cleaned and disinfected regularly. […] The CDC has recommended the below measures to mitigate community spread. All individuals in areas with prevalent COVID-19 should be vigilant for potential symptoms of infection and should stay home as much as possible, practicing social distancing (maintaining a distance of 6 feet from other persons) when leaving home is necessary. […] On April 3, 2020, the CDC issued a recommendation that the general public, even those without symptoms, should begin wearing face coverings in public settings where social-distancing measures are difficult to maintain in order to abate the spread of COVID-19. […] A 2020 study on the effectiveness of facemasks in preventing acute respiratory infections found that surgical masks worn by patients with infections such as rhinovirus, influenza, and seasonal coronaviruses (excluding SARS-CoV-2) reduced the detection of viral RNA in exhaled breaths and coughs. Surgical facemasks were notably effective in significantly decreasing the detection of coronavirus and influenza RNA in aerosols and respiratory droplets. The study suggested that wearing surgical facemasks could help prevent the transmission of human coronaviruses and influenza when worn by symptomatic individuals, which may have implications for controlling the spread of COVID-19.

    COVID-19 (coronavirus disease 2019) is a disease caused by the SARS-CoV-2 virus. It can be very contagious and can spread quickly via droplets released into the air. COVID-19 most often causes respiratory symptoms that can feel much like a cold, the flu, or pneumonia. COVID-19 may attack more than your lungs and respiratory system. Other parts of your body may also be affected by the disease. Most people with COVID-19 have mild symptoms, but some people become severely ill. People who are up to date with their COVID-19 vaccine have lower risk of severe illness. Practice good hygiene by covering coughs and sneezes, washing or sanitizing hands often, and cleaning frequently touched surfaces. […] COVID-19 vaccination is recommended if you are pregnant, breastfeeding a baby, trying to get pregnant now, or might become pregnant in the future. […] COVID-19 vaccines help prevent disease, hospitalization, and death. Unvaccinated people are more likely to get COVID-19 and much more likely to be hospitalized and to die from COVID-19, compared to people who are up to date with their COVID-19 vaccinations.

    Frequently touched objects and surfaces should be cleaned and disinfected regularly. […] The CDC has recommended the below measures to mitigate community spread. All individuals in areas with prevalent COVID-19 should be vigilant for potential symptoms of infection and should stay home as much as possible, practicing social distancing (maintaining a distance of 6 feet from other persons) when leaving home is necessary. […] On April 3, 2020, the CDC issued a recommendation that the general public, even those without symptoms, should begin wearing face coverings in public settings where social-distancing measures are difficult to maintain in order to abate the spread of COVID-19. […] A 2020 study on the effectiveness of facemasks in preventing acute respiratory infections found that surgical masks worn by patients with infections such as rhinovirus, influenza, and seasonal coronaviruses (excluding SARS-CoV-2) reduced the detection of viral RNA in exhaled breaths and coughs. Surgical facemasks were notably effective in significantly decreasing the detection of coronavirus and influenza RNA in aerosols and respiratory droplets. The study suggested that wearing surgical facemasks could help prevent the transmission of human coronaviruses and influenza when worn by symptomatic individuals, which may have implications for controlling the spread of COVID-19.
