SINGAPORE - The number of dengue cases spiked to 594 in the week from Feb 14 to 20, following three consecutive weeks of decline.
Another 107 cases were reported from Sunday (Feb 21) to Monday at 3.30pm. A total of 4,072 people have been infected with the virus since Jan 3.
NEA announced last week that dengue cases could hit a historic high of over 30,000 this year, breaking the previous record of 22,170 set in 2013.
With factors such as warmer temperatures due to the El Nino phenomenon and a switch in the predominant virus serotype to DEN-2 from DEN-1 contributing to the current dengue outbreak, NEA has pledged to step up inspections islandwide and intensify outreach efforts.
The agency said it has observed a 50-per-cent increase in the number of mosquitoes caught in its Gravitraps in January, compared to the same month last year. The number of breeding sites found in homes over the same period also rose by 50 per cent.
There was some good news, however, for residents in Tampines, after two dengue clusters - one of them the biggest cluster in Singapore with 278 cases - were removed from the NEA's dengue website last week.
No new cases had been reported in both clusters over the past two weeks, thanks to collective efforts to stem mosquito breeding.
The biggest dengue cluster listed is now located in Yishun Ring Road and Yishun Street 81, with 109 cases.
