Información en Español

Zika virus is spread to people primarily through mosquito bites. The mosquitoes that spread Zika can bite at day and night.  Zika virus can also be spread during sex with a person who has Zika to his or her sex partners  and from a pregnant woman to her fetus during pregnancy.                   

Many people infected with Zika won't have symptoms or will only have mild symptoms.  The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis (red eyes).  


The best way to prevent Zika is to prevent mosquito bites.  
Use EPA-registered insect repellent.  If you use both sunscreen and insect repellent, apply the sunscreen first and then the repellent.  
Wear long-sleeved shirts and long pants. 
Stay in places with air conditioning or window and door screens. 
Remove standing water around your home.  

Zika and Traveling

Mosquitoes spread many types of viruses and parasites that can cause disease like chikungunya, dengue, Zika, and malaria.  If you are traveling to an area with active Zika cases, we encourage you to create a Zika Prevention Kit(ZPK).  The products in a ZPK can help protect you from Zika.
