A mosquito becomes infected when it bites a person already infected with Zika. That mosquito can then spread the virus by biting more people.

Women should avoid getting pregnant for six months from the time that they or their partners have had a ZIKA virus infection, or traveled to an area with a chance of Zika infection. Practice safe sex methods (such as using condoms) for six months with any partners who have had Zika infection or traveled to an area with a chance of Zika infection.

Zika Treatment

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. Other symptoms include muscle pain and headache. Symptoms can last for several days to a week. People usually don’t get sick enough to go to the hospital.

Risk of Birth Defects

Zika infection during pregnancy can cause a fetus to have 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 have also been increased reports of Guillain-Barré syndrome, an uncommon sickness of the nervous system, in areas affected by Zika.

How to Prevent Zika

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 long-sleeved shirts and long pants.
  • Stay in places with air conditioning and window and door screens to keep mosquitoes outside.
  • Take steps to control mosquitoes inside and outside your home.
  • Treat your clothing and gear with permethrin or buy pre-treated items.
  • Use Environmental Protection Agency (EPA)-registered insect repellents. Always follow the product label instructions.
  • When used as directed, these insect repellents are proven safe and effective even for pregnant and breastfeeding women.
  • Do not use insect repellents on babies younger than 2 months old.
  • Do not use products containing oil of lemon eucalyptus or para-menthane-diol on children younger than 3 years old.
  • Mosquito netting can be used to cover babies younger than 2 months old in carriers, strollers, or cribs to protect them from mosquito bites.
  • Sleep under a mosquito bed net if air conditioned or screened rooms are not available or if sleeping outdoors.
  • Prevent sexual transmission of Zika by using condoms or not having sex.
