In just one week, Zika cases in Singapore have gone from zero to 258, raising concerns about a potential rapid surge in cases across Asia.
A recent study estimates that roughly 2.6 billion people in the region and Africa could be at risk of contracting the virus, which has been linked to the neurological disorder microcephaly in unborn babies.
It’s not yet clear why Zika has spread so suddenly in Singapore. Many of the cases are thought to be locally-transmitted by the Aedes aegypti mosquito.
