ATLANTA, Ga. (WPVI) --Cases of the mosquito-borne Zika virus have been found in several more states including Illinois, Texas and Florida.
A case was already diagnosed in Hawaii.
All of them are in people who have traveled to areas in Central and South America where the virus is much more prevalent.
The Centers for Disease Control and Prevention is advising anyone visiting these areas, especially pregnant women, to take precautions to prevent mosquito bites.
The Zika virus typically causes mild symptoms of fever, rash, joint pain and pink eye.
But there is concern that the virus may cause a severe and potentially fatal birth defect.
If you are pregnant and have traveled to affected areas, you're asked to be evaluated by your doctor.
