Questions about Zika
Zika virus disease is caused by the Zika virus, which is spread to people primarily through the bite of an infected mosquito (Aedes aegypti
and Aedes albopictus
). The illness is usually mild with symptoms lasting up to a week, and many people do not have symptoms or will have only mild symptoms. However, Zika virus infection during pregnancy can cause a serious birth defect called microcephaly and other severe brain defects.
Prevent Mosquito Bites
Use Environmental Protection Agency (EPA)-registered insect repellents with one of the active ingredients below. When used as directed, EPA-registered insect repellents are proven safe and effective, even for pregnant and breastfeeding women.
Temperatures could accelerate the success of a Zika vaccine
As warmer temperatures herald annoying mosquitoes, the researchers are feverishly working on several promising vaccines against zika, a virus known to infect humans through the bite of this insect. The speed and debilitating effects of last year's zika outbreak in the Western Hemisphere generated a race to develop a vaccine. Just over a year after this pandemic was declared a global health emergency, a group of volunteers are undergoing preliminary testing.
