Most Zika virus infections are caused by the bite of an infected mosquito. Locally mosquito-transmitted Zika virus has not been reported in the continental United States so far, but there have been confirmed travel-associated cases reported. If you’re traveling, especially if you’re pregnant, learn about ways to avoid mosquito bites.
Ebola is a rare and deadly infection spread through direct contact with blood and body fluids of a person with the virus, or with objects that have been contaminated with it. The 2014 outbreak in West Africa is the largest in history, but does not pose a significant threat to the United States.
