When the first blood tests confirm the existence of the Zika virus
Health workers in Brazil say they’ve detected the Zika-like virus in blood samples of people who tested positive for it.
A blood test confirmed the presence of Zika virus in a Brazilian woman in August, according to state health officials.
They’re hoping to confirm the diagnosis on Wednesday.
Health workers in Sao Paulo, Brazil, on Thursday announced that they’ve tested dozens of people for the virus.
Health officials say they’ll continue to monitor those who tested negative, and that all cases of Zika will be reported to the state’s health department.
