The CDC is advising pregnant women to postpone travel to areas affected by Zika. Birth defects have been reported in Brazil of babies whose mothers were infected with the virus during pregnancy. Microcephaly, a condition where a baby’s head is smaller than expected, has been the most reported birth defect. However, if an expecting mother is infected with the virus during pregnancy, the risk is unknown to the infant.Prevention & Treatment
There is no vaccine available to prevent Zika virus disease. The best way to prevent Zika is to avoid mosquito bites. If you do become infected, treat your symptoms by:- Plenty of rest
- Drink fluids to stay hydrated
- Take medicines such as acetaminophen to relieve pain and fever
- Aspirin and NSAIDs (such as ibuprofen and naproxen) should be avoided until dengue can be ruled out to reduce risk of bleeding
- Prevent mosquito bites during the first week of infection, due to the virus being found in the blood and can be passed to another mosquito through mosquito bites. Therefore, the infected mosquito can spread the virus to other people.
- It has been reported that the virus can be spread through sexual contact
