Detailed explanation-1: -A pregnant woman can pass Zika virus to her fetus during pregnancy. Zika is a cause of microcephaly and other severe fetal brain defects. We are studying the full range of other potential health problems that Zika virus infection during pregnancy may cause.

Detailed explanation-2: -Overview. Zika is a mosquito-borne virus, similar to dengue fever, yellow fever and West Nile virus. The infection is associated with a birth defect called microcephaly, which can affect babies born to people who become infected with Zika while pregnant.

Detailed explanation-3: -Zika virus infection during pregnancy is a cause of microcephaly. During pregnancy, a baby’s head grows because the baby’s brain grows. Microcephaly can occur because a baby’s brain has not developed properly during pregnancy or has stopped growing after birth.

Detailed explanation-4: -Zika is spread mostly by the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus). These mosquitoes bite during the day and night. Zika can be passed from a pregnant woman to her fetus.

Detailed explanation-5: -Zika virus is primarily transmitted to people through the bite of an infected mosquito from the Aedes genus, mainly Aedes aegypti in tropical regions. Aedes mosquitoes usually bite during the day, peaking during early morning and late afternoon/evening.
