The National Environment Agency (NEA) has detected more Aedes aegypti mosquitoes in recent months, renewing concerns over a dengue flare-up in Singapore.

Minister for the Environment and Water Resources Masagos Zulkifli said yesterday that 22 per cent more Aedes aegypti mosquitoes were found in the first three months of this year compared with the previous three months. They are responsible for the transmission of dengue, which saw a 16-year low in case numbers last year.

"We must be extra vigilant, especially since we are approaching the traditional peak dengue period," Mr Masagos said at the launch of National Dengue Prevention Campaign.
