The outbreak of the Zika virus spread in Southeast Asia Thursday, after Singapore noted that total cases had risen to 115 while Malaysia confirmed that its first reported case was a woman who had traveled to the neighboring city-state.
The woman was diagnosed with Zika after she experienced rash and a fever for a week after her Singapore trip, Malaysia's Health Minister Subramaniam Sathasivam told Reuters.
The woman's child, who is in Singapore, and four other Malaysian nationals also tested positive for the virus, Reuters reported.
Malaysia, which shares a border with Singapore, has been taking precautionary measures since Monday such as scanning people to detect fever at major entry points and various airports, The Straits Times reported.
Singapore also announced late Wednesday its first case of a pregnant woman testing positive for locally-transmitted Zika virus, as a potential new infection cluster emerged.
