Zika Virus Disease

Zika virus is spread primarily through the bite of an infected Aedes species mosquito. Zika can also be transmitted through sex and from a pregnant woman to her fetus. Many people infected with Zika won’t have symptoms or will only have mild symptoms. The most common symptoms are fever, rash, joint pain, or red eyes. Symptoms can last for several days to a week. However, Zika infection during pregnancy can cause a birth defect of the brain called microcephaly. Other problems have been detected among fetuses and infants infected with Zika virus before birth, such as defects of the eye, hearing deficits, and impaired growth. There is no vaccine to prevent Zika. The best way to prevent diseases spread by mosquitoes is to protect yourself and your family from mosquito bites. Here’s how:

  • Wear insect repellent
  • Cover up with long-sleeved shirts and long pants
  • Use condoms with a partner who has been in an area with Zika
  • Remove standing water in your home and around your community
  • Stay in places with air conditioning and window and door screens to keep mosquitoes outside
  • Clean up trash, containers, and tires that can hold water
  • Use larvicides in water that can’t be removed and won’t be used for drinking
