Health officials are asking Pennsylvanians to pay attention to travel advisories as they test six to eight people for the mosquito-borne Zika virus. No cases are confirmed yet.

Loren Robinson of the Pennsylvania Department of Health said Friday that each person being tested had traveled to an area affected by Zika.

The virus' symptoms tend to be slight, and include fever, rash, pain or conjunctivitis. Health officials suspect the infection causes a birth defect called microcephaly, in which a babies' head is smaller than normal and the brain may not have developed properly.

Brazil is seeing a wave of such birth defects.

Health officials are advising pregnant women to consider postponing travel to areas where the Zika virus transmission is active. Those areas include Mexico and parts of Central and South America.
