Mosquitoes in Cuba

Overall Risk: Moderate

Cuba has year-round mosquito activity, with peak risk during the wet season from May through October. The entire island is at risk, with urban areas including Havana, Santiago de Cuba, and Camaguey experiencing significant dengue exposure. Stagnant water from aging infrastructure creates abundant breeding sites.

Precautions

CDC recommends EPA-registered repellents containing DEET, picaridin, IR3535, or oil of lemon eucalyptus
WHO advises long-sleeved clothing and long trousers during dusk and dawn hours
WHO recommends permethrin-treated bed nets where accommodation is open-air or unscreened
WHO emphasises eliminating standing water to prevent Aedes breeding
CDC recommends intact window screens in accommodation
CDC recommends antimalarial chemoprophylaxis for travellers to malaria transmission zones

Cuba Mosquito Season

Cuba has year-round mosquito activity, with peak risk during the wet season from May through October. The entire island is at risk, with urban areas including Havana, Santiago de Cuba, and Camaguey experiencing significant dengue exposure. Stagnant water from aging infrastructure creates abundant breeding sites.

WHO and CDC surveillance reports indicate that the seasonal mosquito risk in Cuba aligns with rainfall patterns and temperature, with peak transmission of Cuba's most-reported disease (Dengue Fever) typically following the wet season. Travel timing should account for these climatic windows.

Mosquito-Borne Diseases in Cuba

Mozzwise tracks 4 mosquito-borne diseases in Cuba based on WHO, CDC, and ECDC surveillance. Each entry below cross-links to a full Mozzwise disease briefing.

Dengue Fever is recorded in Cuba with moderate severity according to current surveillance. Travelers to endemic areas, young children, pregnant women, and people with prior dengue infection. A second infection with a different serotype carries a significantly higher risk of severe disease. Reported globally in: Tropical and subtropical regions worldwide — Southeast Asia, Latin America, Sub-Saharan Africa, Pacific Islands.

Chikungunya is tracked as present in Cuba based on historical surveillance, though active transmission is not currently flagged. Elderly travelers, newborns, and people with chronic conditions like diabetes or heart disease. The debilitating joint pain can persist for months or years, significantly affecting quality of life. Reported globally in: Africa, Asia, Indian subcontinent, Americas. Expanding into southern Europe (Italy, France, Spain).

West Nile Virus is tracked as present in Cuba based on historical surveillance, though active transmission is not currently flagged. Adults over 60 and immunocompromised travelers face the greatest risk of severe neuroinvasive disease. There is no vaccine and no specific treatment — taking precautions is your only protection. Reported globally in: Americas, Europe (expanding since 2010), Middle East, parts of Africa. Peak in late summer.

Zika Virus is tracked as present in Cuba based on historical surveillance, though active transmission is not currently flagged. Pregnant women and those planning pregnancy are the primary concern. The virus can cause devastating birth defects including microcephaly. Most adults recover without issues within a week. Reported globally in: Tropical Americas, Southeast Asia, Pacific Islands. Ongoing low-level transmission since the 2015-2016 epidemic.

Mosquito Species in Cuba

Travelers in Cuba are most likely to encounter the following mosquito species. Each species has a distinct biting pattern (day vs night) and habitat — understanding which you may meet shapes when protection matters most.

SpeciesCarriesWhen It BitesHabitat
Aedes aegyptiDengue fever, Zika virus, Chikungunya, Yellow feverDay-biting with peaks in early morning and late afternoonUrban and peri-urban environments closely tied to human habitation
Aedes albopictusDengue fever, Chikungunya, Zika virusAggressive daytime biter, active throughout daylight hours with less pronounced dawn/dusk peaks than AeHighly adaptable — urban, suburban, peri-urban, semi-rural, and forest-edge environments
Culex pipiensWest Nile virus, St. Louis encephalitisDusk-to-night biterAny stagnant water — drains, catch basins, birdbaths, unused pools, clogged gutters, containers
Culex quinquefasciatusWest Nile virus, St. Louis encephalitis, Lymphatic filariasis, Japanese encephalitisDusk-to-dawn biter, indoors and outdoors, year-round in tropical climatesPolluted water bodies associated with poor sanitation — open drains, cesspools, septic tanks, wastewater channels, storm drains

How to Avoid Mosquito Bites in Cuba

Public health agencies converge on a layered approach to reducing mosquito bites in Cuba. The core recommendations across CDC, WHO, and ECDC are as follows.

Skin-applied repellents. CDC recommends EPA-registered repellents containing one of four tested active ingredients: DEET, picaridin, IR3535, or oil of lemon eucalyptus / para-menthane-diol. CDC advises applying sunscreen first and repellent on top, and reapplying at the interval stated on the product label.

Permethrin-treated clothing. WHO and CDC both recommend permethrin treatment of trousers, long-sleeved shirts, and socks for settings with sustained mosquito exposure. Permethrin binds to fabric and is effective against both Aedes and Anopheles species. It is not applied to skin.

Accommodation. Air-conditioned rooms with intact window screens substantially reduce indoor exposure. Bed nets — ideally permethrin-treated — are standard in open-air or budget accommodation. WHO emphasises removing standing water around accommodation, as even bottle caps, plant saucers, and water-storage containers can support Aedes breeding.

Timing. Aedes vectors active in cities and resort areas typically bite in daylight, with peaks in early morning and late afternoon. Anopheles vectors active in forested or rural areas typically bite at night.
