People who get sick can take medicines similar to acetaminophen to cut back the fever and ache associated to the an an an an infection.
5. Zika virus an an an an infection in pregnant women will also be linked to starting defects.
It is potential that there is a hyperlink between Zika virus and newborns with microcephaly— a congenital scenario that results in decreased concepts development and abnormally small heads, although this is not confirmed, in accordance with researchers.
The alarming enhance in microcephaly in optimistic areas of the Americas has led the CDC and the Public Correctly being Company of Canada to warning pregnant women and girls considering turning into pregnant to postpone their journey to affected areas.
