the bite of Aedes aegypti, a mosquito common in tropical climates and
especially in cities.
Another species, A. albopictus, which thrives in cooler climes, may also be
able to transmit the bug, though possibly not as efficiently. Unusually for
a mosquito-borne virus, Zika can also be transmitted sexually (the first
case of transmission in the United States occurred this way).
Studies are under way to find out how long after infection that remains
possible, but traces of the virus’s genetic code have been found in semen
six months after the onset of symptoms. Infection through blood transfusion
has been confirmed as well.
The virus has also turned up in urine, tears and saliva, though that does
not necessarily mean that it can spread through them. | m**c
