Two days after the World Health Organization declared Zika virus an emergency, the first incident of the virus has been reported in the U.S.
Zika virus, spread through the bite of the Aedes aegypti mosquito has spread through Latin America and has been linked with a high incidence of microcephaly.
An unidentified person in Texas has contracted the Zika virus after sexual intercourse with a person who had contracted the virus in Venezuela.
There is now strong speculation that Zika virus can possibly be sexually contracted. Zika virus is usually hard to detect, with mild symptoms and no known cure.
