• The mosquitoes that spread Zika are called Aedes aegypti and Aedes albopictus. These mosquitoes live for about 2 to 3 weeks, indoors or outside.
• They’re called day biters because they bite most often during the day, but they also bite at night.
• These mosquitoes become infected with Zika when they bite someone who has the virus during the first week of infection.
• Three to five days after biting someone, the female lays her eggs. Mosquitoes from these eggs aren’t infected with Zika – they have to bite an infected person to become a Zika carrier.
• These mosquitoes can lay their eggs in a bottle cap full of water! This is why getting rid of standing water in pet dishes, flower pots, bowls, bird baths, and other places is very important.
• The Aedes aegypti and Aedes albopictus live in various parts of the United States. Here is a map from the CDC of the best estimate of where these mosquitoes are or have been previously found.
Recently, there have been cases of local transmission of Zika in Florida.It is expected that mosquitoes may bite infected individuals and then spread the virus. If a pregnant woman gets Zika, she can pass it to her baby.
Zika infection during pregnancy causes a birth defect called microcephaly, which has been linked to developmental delay, intellectual disabilities, seizures and other problems.
Zika infection during pregnancy also may be linked to:
• Other birth defects, including hearing loss and problems with the eyes
• Other severe brain defects.
Even among pregnant women with no symptoms of the virus, if they test positive for Zika, their babies may be harmed.
We don’t know the full impact of this virus on the long term development of babies and children.
