Zika virus is primarily spread through the bites of infected mosquitoes. There is no vaccine to prevent Zika virus infection, and there is no specific treatment for people who become infected. Although Zika virus is primarily spread by infected mosquitoes, exposure to an infected person’s blood or other body fluids may also result in transmission. Outdoor workers may be at the greatest risk of exposure to Zika virus. Some workers, including those working with insecticides in areas of active Zika transmission to control mosquitoes and healthcare workers who may be exposed to contaminated blood or other potentially infectious materials from people infected with Zika virus, may require additional protection. Although there are no reports of transmission of Zika virus from infected patients to health care personnel or other patients, minimizing exposure to body fluids is important to reduce the possibility of such transmission. CDC has previously recommended Standard Precautions in all health care settings to protect both health care personnel and patients from infection with Zika virus as well as from blood-borne pathogens (e.g., human immunodeficiency virus [HIV] and hepatitis C virus [HCV]).

CDC will continue to update its guidance related to occupational exposure to Zika and related health effects based on the accumulating evidence, expert opinion, and knowledge about the risk associated with other viral infections. For updates, visit: www.cdc.gov/zika
