Zika virus is transmitted to humans through the bites of infected Aedes mosquitoes. Most people infected with Zika virus do not develop symptoms, but when symptoms do occur they are usually mild and last only a few days. In rare cases, Zika virus infection during pregnancy can cause microcephaly and other birth defects. There is no vaccine or treatment for Zika virus, so prevention focuses on mosquito control and personal protective measures against mosquito bites.

through the bite of an infected
mosquito from the Aedes genus, mainly
Aedes aegypti in urban areas and

• Neonatal malformation: Microcephaly which is a
condition where a baby’s head is smaller than those
of other babies of the same age and sex. 
PREVENTION AND TREATMENT
