What is the Zika virus? How do you catch it?
aedes albopictus mosquito
The Zika virus, first identified in Uganda in 1947, is transmitted by the same type of mosquito that carries dengue fever, yellow fever, and chikungunya virus. A mosquito bites an infected person and then passes those viruses to other people it bites. Outbreaks did not occur outside of Africa until 2007, when it spread to the South Pacific.
The CDC has confirmed Zika can spread through sex, usually after a person traveled to an area where Zika has broken out, got the virus, and gave the virus to a sex partner who did not travel. Infected women and men can both pass the virus to sex partners -- even if they haven’t shown symptoms of infection, the CDC says.
The CDC is aware of a report that Brazilian scientists have found the virus in the saliva and urine of infected people, Frieden has said, but more information is needed.
