SINGAPORE - The number of new dengue cases last week dropped to 138, the lowest weekly figure this year, according to the latest figures on the National Environment Agency's (NEA) dengue website.

There were 138 reported cases of the mosquito-borne virus - 35 cases fewer than the previous week. A total of 12,034 dengue cases have been reported since the start of the year - more than the 11,286 cases in 2015.

With Singapore still in the traditional peak dengue season, the NEA said it is still anticipating an upward trend in the number of cases.

It warned in February that there could be more than 30,000 cases this year - higher than the historic 22,170 cases reported in 2013.

NEA's Gravitrap data has also shown a steady increase in the Aedes aegypti mosquito population, indicating an abundance of the mosquito vector in the community.

The mosquito is responsible for transmitting both the dengue and Zika viruses, as well as yellow fever and chikungunya.

Meanwhile, the number of dengue clusters across the island continues to decrease. As of Monday (Oct 3), there were 26 compared to the 35 reported last week. Six are classified as high risk.

A cluster at Yishun Avenue 4 and Yishun Street 61 remains as the highest risk with a total of 61 cases, including five cases in the last fortnight.
