Seventh Zika case reported among S.C. residents

Aedes aegypti mosquito is photographed through a microscope. The mosquito behind the Zika virus seems to operate like a heat-driven missile of disease. Scientists say the hotter it gets, the better the mosquito that carries Zika virus is at transmitting a variety of dangerous illnesses.

A seventh South Carolina resident has been diagnosed with the Zika virus.

The South Carolina Department of Health and Environmental Control reported on Tuesday that the patient contracted the virus while traveling internationally and was diagnosed after returning home.

Six cases in this state have occurred that way.

The other case involved a resident who had sexual contact with someone who acquired the Zika infection while traveling abroad.

The Zika virus is transmitted by the Aedes aegypti and Aedes albopictus mosquitoes — both of which are found in South Carolina. There is no evidence that they are spreading the disease locally.
