Denga
Zapobieganie i profilaktyka

Denga jest wirusową chorobą przenoszoną przez komary Aedes aegypti, której profilaktyka opiera się na kompleksowej ochronie przed ukąszeniami oraz kontroli populacji wektorów. Zalecane środki ochronne obejmują stosowanie repelentów zawierających DEET (20-30%), pikarydynę, IR3535 lub olejek z eukaliptusa cytrynowego, noszenie odzieży zakrywającej ciało, używanie permetryny na odzież i sprzęt oraz korzystanie z klimatyzowanych lub zabezpieczonych moskitierami pomieszczeń. Kluczowe jest także eliminowanie miejsc rozrodu komarów poprzez regularne opróżnianie pojemników z wodą, szczelne przykrywanie zbiorników, usuwanie przedmiotów gromadzących wodę oraz stosowanie larwicydów i naturalnych drapieżników larw. Szczepionki przeciwko dendze, takie jak Dengvaxia (3 dawki co 6 miesięcy, skuteczność ~80%, stosowana u dzieci 9-16 lat z potwierdzonym wcześniejszym zakażeniem) oraz Qdenga (2 dawki co 3 miesiące, stosowana u dzieci 6-16 lat, także u osób bez wcześniejszego zakażenia), stanowią uzupełnienie profilaktyki, ale nie zastępują innych metod ochrony.

Profilaktyka Dengi

Denga (dengue fever) to choroba wirusowa przenoszona przez komary gatunku Aedes, głównie Aedes aegypti. Zapobieganie zakażeniu wirusem dengi opiera się na kompleksowych działaniach, które mają na celu zarówno unikanie ukąszeń komarów, jak i ograniczanie ich populacji w środowisku. Obecnie dostępne są również szczepionki przeciwko dendze, jednak ich zastosowanie podlega określonym wskazaniom i ograniczeniom.12

Ochrona przed ukąszeniami komarów

Podstawowym sposobem zapobiegania dendze jest ochrona przed ukąszeniami komarów przenoszących wirusa. Komary Aedes są aktywne głównie w ciągu dnia, szczególnie o świcie i zmierzchu, ale mogą atakować również w nocy.34 Zalecane środki ochronne obejmują:

  • Noszenie luźnej odzieży zakrywającej jak największą powierzchnię ciała (długie rękawy, długie spodnie, skarpety i buty zakryte)13
  • Stosowanie środków odstraszających komary (repelentów) zawierających:
  • Stosowanie permetryny na odzież, sprzęt kempingowy i moskitiery (nie należy nanosić bezpośrednio na skórę)36
  • Korzystanie z klimatyzowanych lub odpowiednio zabezpieczonych pomieszczeń:
    • Instalowanie i utrzymywanie moskitier w oknach i drzwiach8
    • Przebywanie w pomieszczeniach klimatyzowanych9
  • Stosowanie moskitier podczas snu, zwłaszcza w ciągu dnia lub gdy pomieszczenia nie są klimatyzowane lub zabezpieczone210
  • Ograniczanie aktywności na zewnątrz w godzinach największej aktywności komarów1011

Eliminacja miejsc rozmnażania komarów

Komary Aedes składają jaja w stojącej wodzie, dlatego kluczowym elementem zapobiegania dendze jest eliminacja miejsc, w których mogą się rozmnażać. Należy podjąć następujące działania:312

  • Regularne opróżnianie i czyszczenie pojemników mogących gromadzić wodę (doniczki, wazony, pojemniki na wodę) przynajmniej raz w tygodniu213
  • Szczelne przykrywanie zbiorników na wodę (cysterny, beczki, studnie)1415
  • Usuwanie lub właściwe składowanie przedmiotów, które mogą gromadzić deszczówkę (zużyte opony, puszki, butelki)1617
  • Dbanie o drożność rynien i odpływów wody15
  • Wyrównywanie terenu w celu zapobiegania tworzeniu się kałuż15
  • Stosowanie larwicydów w zbiornikach wodnych, których nie można opróżnić lub usunąć1819
  • Wprowadzanie naturalnych wrogów larw komarów, takich jak ryby żyworodne (np. Poecilia reticulata) do zbiorników wodnych19

Szczepienia przeciwko dendze

Obecnie dostępne są dwie szczepionki przeciwko dendze, które zostały zatwierdzone w różnych krajach:202

Szczepionka Dengvaxia (CYD-TDV)

Szczepionka Dengvaxia została zatwierdzona do stosowania w Stanach Zjednoczonych i kilku innych krajach z następującymi zaleceniami:2122

  • Przeznaczona dla dzieci i młodzieży w wieku 9-16 lat
  • Wymagane laboratoryjne potwierdzenie przebytego wcześniej zakażenia wirusem dengi
  • Zalecana dla osób mieszkających w obszarach endemicznego występowania dengi (np. terytoria USA takie jak Portoryko, Amerykańskie Samoa, Wyspy Dziewicze)
  • Nie jest zalecana dla osób bez wcześniejszego zakażenia wirusem dengi ze względu na zwiększone ryzyko ciężkiego przebiegu choroby w przypadku pierwszego naturalnego zakażenia po szczepieniu22
  • Schemat szczepienia obejmuje 3 dawki podawane w odstępach 6-miesięcznych23
  • Skuteczność szczepionki wynosi około 80% w zapobieganiu chorobie, hospitalizacji i ciężkiemu przebiegowi dengi u dzieci, które wcześniej przebyły infekcję2321
Szczepionka Qdenga (TAK-003)

Szczepionka Qdenga została zatwierdzona w Unii Europejskiej i niektórych innych krajach:202

  • Przeznaczona dla osób w wieku 6-16 lat (zakres wieku może się różnić w zależności od kraju)
  • W niektórych krajach może być podawana zarówno osobom z wcześniejszym zakażeniem wirusem dengi, jak i bez takiego zakażenia13
  • Zalecana głównie w obszarach o wysokiej transmisji wirusa dengi
  • Schemat szczepienia obejmuje 2 dawki podawane w odstępie 3 miesięcy13

Ważne jest, aby podkreślić, że szczepionki przeciwko dendze nie są zalecane jako jedyny środek zapobiegawczy, ale powinny być stosowane w połączeniu z innymi metodami kontroli wektorów i zapobiegania ukąszeniom komarów.324

Zapobieganie podczas podróży

Osoby podróżujące do obszarów, gdzie występuje denga, powinny podjąć dodatkowe środki ostrożności:19

  • Przed podróżą:
    • Sprawdzić, czy w miejscu docelowym występuje ryzyko zachorowania na dengę925
    • Skonsultować się z lekarzem lub odwiedzić klinikę medycyny podróży, najlepiej 6 tygodni przed wyjazdem26
    • Zabrać ze sobą odpowiednie środki ochronne (repelenty, moskitiery)9
    • Zabrać paracetamol do kontroli gorączki i bólu w przypadku zachorowania27
  • Podczas podróży:
    • Stosować wszystkie środki ochrony przed ukąszeniami komarów wymienione wcześniej
    • Wybierać zakwaterowanie z klimatyzacją lub moskitierami w oknach i drzwiach9
  • Po powrocie z podróży:
    • Kontynuować stosowanie środków ochrony przed ukąszeniami komarów przez 3 tygodnie po powrocie, nawet jeśli nie występują objawy choroby – pozwoli to zapobiec przenoszeniu wirusa na lokalne komary19
    • W przypadku wystąpienia objawów podobnych do dengi (gorączka, bóle głowy, bóle mięśni i stawów, wysypka) skontaktować się z lekarzem i poinformować o odbytej podróży427

Profilaktyka w przypadku zachorowania

Osoby, u których zdiagnozowano dengę, powinny podjąć dodatkowe środki ostrożności, aby zapobiec dalszemu rozprzestrzenianiu się choroby:28

  • Unikać ukąszeń komarów przez co najmniej 5-12 dni od wystąpienia objawów, aby zapobiec przenoszeniu wirusa na komary, które mogłyby następnie zakazić inne osoby2814
  • Stosować repelenty, nosić odzież ochronną i korzystać z moskitier
  • W obszarach, gdzie występują komary Aedes, pacjenci powinni być izolowani pod moskitierą do czasu ustąpienia drugiej fali gorączki22

Pasywna immunizacja i nowe metody zapobiegania

Oprócz tradycyjnych metod zapobiegania dendze, prowadzone są badania nad nowymi strategiami profilaktycznymi:2919

Działania na poziomie społeczności i programy zdrowia publicznego

Skuteczne zapobieganie dendze wymaga zintegrowanego podejścia obejmującego działania na poziomie społeczności i programy zdrowia publicznego:1612

  • Zintegrowana strategia zarządzania zapobieganiem i kontrolą dengi (IMS-dengue) wdrażana przez PAHO/WHO12
  • Programy edukacyjne zwiększające świadomość społeczną na temat dengi i metod jej zapobiegania3233
  • Mobilizacja społeczności lokalnych i aktywacja lokalnego przywództwa w inicjowaniu strategii zapobiegawczych32
  • Współpraca międzysektorowa między instytucjami rządowymi i pozarządowymi12
  • Wykorzystanie mediów społecznościowych i innych platform do szerszego rozpowszechniania informacji o profilaktyce dengi33
  • Programy nadzoru entomologicznego i monitorowania oporności na insektycydy16

Znaczenie profilaktyki dengi

Zapobieganie dendze ma kluczowe znaczenie ze względu na brak swoistego leczenia przyczynowego tej choroby. Wczesne wykrycie i dostęp do odpowiedniej opieki medycznej mogą znacznie zmniejszyć śmiertelność w przypadku ciężkiej dengi, jednak głównym celem pozostaje zapobieganie infekcji.234

W obliczu wzrostu liczby przypadków dengi na całym świecie, spowodowanego zmianami klimatycznymi, urbanizacją i zwiększoną mobilnością ludności, skuteczne strategie zapobiegawcze stają się coraz ważniejsze. Kompleksowe podejście obejmujące kontrolę wektorów, szczepienia (gdzie są zalecane), edukację społeczną i indywidualne środki ochronne stanowi najlepszą strategię zapobiegania tej chorobie.3536

Należy podkreślić, że w przypadku dengi nie ma jednej uniwersalnej metody zapobiegania, a najskuteczniejsze jest łączenie różnych strategii i dostosowywanie ich do lokalnych warunków epidemiologicznych, społecznych i środowiskowych.3735

    Researchers are working on dengue fever vaccines. For now, in areas where dengue fever is common, the best ways to prevent infection are to avoid being bitten by mosquitoes and to take steps to reduce the mosquito population. […] The World Health Organization stresses that the vaccine is not an effective tool on its own to reduce dengue fever in areas where the illness is common. Preventing mosquito bites and controlling the mosquito population are still the main methods for preventing the spread of dengue fever. […] If you live in or travel to an area where dengue fever is common, these tips may help reduce your risk of mosquito bites: Stay in air-conditioned or well-screened housing. The mosquitoes that carry the dengue viruses are most active from dawn to dusk, but they can also bite at night. Wear protective clothing. When you go into mosquito-infested areas, wear a long-sleeved shirt, long pants, socks and shoes. Use mosquito repellent. Permethrin can be applied to your clothing, shoes, camping gear and bed netting. You can also buy clothing made with permethrin already in it. For your skin, use a repellent containing at least a 10% concentration of DEET. Reduce mosquito habitat. The mosquitoes that carry the dengue virus typically live in and around houses, breeding in standing water that can collect in such things as used automobile tires. You can help lower mosquito populations by eliminating habitats where they lay their eggs. At least once a week, empty and clean containers that hold standing water, such as planting containers, animal dishes and flower vases. Keep standing water containers covered between cleanings.

  • #18 Kao | Prevention and Countermeasures for Dengue Fever
    https://www.kao.com/global/en/innovation/research-development/dengue/dengue-fever/prevention/
    To prevent dengue infection, it is important to avoid being bitten by mosquitoes that carry the virus. […] To prevent mosquito bites, it is effective to use countermeasure products (e.g., repellents, insecticides, mosquito coils, mosquito nets, screen doors), and to minimize skin exposure using long sleeved clothes. […] Therefore, indoor mosquito control is important in Southeast Asia. It is also important to create an environment that eliminates puddles and tubs around the house that allow mosquitoes to spawn outdoors. In some cases, larvicide is used in water tanks to prevent mosquito outbreaks.
