Zika virus (Zika) is spreading in multiple countries and territories. Please share the following information with those who may find it useful.

Types of Cases

Zika virus is spread to people primarily through the bite of an infected Aedes species mosquito (A. aegypti and A. albopictus). To date, Zika has not been spread by mosquitoes in the continental United States. However, travel-associated cases and cases of sexual transmission have been reported in travelers returning to the United States.

With the recent outbreaks in the Americas, the number of Zika cases among travelers visiting or returning to the United States will likely increase. CDC is not able to predict how much Zika virus would spread in the continental United States. Many areas in the United States have the type of mosquitoes that can become infected with and spread Zika virus. However, recent outbreaks in the continental United States of chikungunya and dengue, which are spread by the same type of mosquito, have been relatively small and limited to a small area.

Zika virus can also be sexually transmitted by a man to his sex partners. Not having sex is the best way to prevent sexually transmitted Zika. If a person is sexually active, using condoms, the right way, every time they have sex can reduce the chance they can get Zika through sex.  


There is no specific medicine or vaccine for Zika virus.

The best way to prevent diseases spread by mosquitoes is to protect yourself and your family from mosquito bites.

  • Wear long-sleeved shirts and long pants.
  • Stay in places with air conditioning and window and door screens to keep mosquitoes outside.
  • 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.
  • Sleep under a mosquito bed net if air conditioned or screened rooms are not available or if sleeping outdoors.


The most common symptoms of Zika virus disease are

  • Fever
  • Rash
  • Joint pain
  • Conjunctivitis (red eyes)

Most people infected with Zika virus won’t even know they have the disease because they won’t have symptoms. The sickness is usually mild with symptoms lasting for several days to a week. People usually don’t get sick enough to go to the hospital, and they very rarely die of Zika.

The following steps can reduce the symptoms of Zika:

  • Get plenty of rest.
  • Drink fluids to prevent dehydration.
  • Take medicine, such as acetaminophen, to reduce fever and pain. 
  • Do not take aspirin or other non-steroidal anti-inflammatory drugs. 
  • If you are taking medicine for another medical condition, talk to your healthcare provider before taking additional medication.
