Singapore investigating Zika strain as infections rise
Singapore officials are investigating the strain and severity of its locally transmitted Zika virus, amid a rising number of cases.
Health Minister Gan Kim Yong told Parliament on Tuesday that it is not yet clear whether the virus found locally causes more or less severe disease than that found in South America.
He said further research will be needed to determine the answer.
Researchers concluded last week that the strain of Zika in two patients in the city state was not from South America, but similar to those found in the region decades ago.
Singapore announced its first Zika infection in May, with the virus imported by a 48-year-old man who had travelled to Brazil.
