Zika Virus Information
In May 2015, Zika virus (pronunciation: zeeka) was found for the first time in the Americas. Currently, a large outbreak is ongoing in the region including South and Central America, Mexico, and the Caribbean, and U.S. citizens travelling to these regions are at risk for infection.  Click HERE for the most up-to-date map of affected countries from the Pan American Health Organization.

Zika virus is transmitted to people by mosquitoes. Illness in healthy people is generally mild.  The most common symptoms of Zika are fever, rash, joint pain, or conjunctivitis (red eyes). Other common symptoms include muscle pain and headache. There is no vaccine to prevent or medicine to treat Zika virus infection.

Important Information for Pregnant Women:
Zika can be transmitted from a pregnant mother to her baby during pregnancy or around the time of birth.  Brazil has reported microcephaly and other poor pregnancy outcomes in babies of mothers who were infected with Zika virus while pregnant.  For more information visit
Until more is known and out of an abundance of caution, pregnant women should consider postponing travel to any area where Zika virus transmission is ongoing. Pregnant women who do travel to one of these areas should talk to their doctors or other healthcare providers first and strictly follow steps to avoid mosquito bites during the trip. Women trying to become pregnant should consult with their healthcare providers before traveling to these areas and strictly follow steps to avoid mosquito bites during the trip.
