Zika is primarily transmitted through the bite of infected Aedes mosquitoes.

  • Mosquitoes become infected when they bite a person already infected with the Zika virus

Zika can also be transmitted from a pregnant mother to her baby during pregnancy or around the time of birth.

  • Stay in places with air conditioning or that use window and door screens to keep mosquitos outside

  • Sleep under a mosquito net if you are overseas or outside and unable to protect yourself from mosquito bites

  • Treat clothing and gear with permethrin or buy permethrin-treated items
