Singapore steps up zika fight after confirming 41 local cases

[SINGAPORE] Singapore has stepped up its fight against the Zika virus after confirming 41 locally transmitted cases one day after reporting its first infection.

The Ministry of Health said it will continue to screen people who had close contact with those infected. Of the 41 people who contracted the virus in Singapore, 34 have fully recovered, the ministry said, with the majority of cases occurring among foreign construction workers.

"Given that the Zika virus is spread by the Aedes mosquito vector, MOH cannot rule out further community transmission in Singapore, since some of those who tested positive also live or work in other parts of Singapore," the ministry said in a Monday statement. It listed seven other "areas of concern" where some of those already infected live.

The National Environment Agency said in the same statement it has intensified efforts to control the Aedes mosquito population, with more than 200 officers inspecting affected areas.

The Zika spread in Singapore highlights the threat of infection across Asia. Indonesia, Thailand and Vietnam have reported cases that were either transmitted locally or brought into the country, according to the Singapore ministry.

While most Zika cases are mild or symptom-free, women infected during pregnancy are at increased risk of giving birth to babies with abnormally small heads, a condition called microcephaly.
