Less than one month ago, the Singapore National Environment Agency (NEA) reported an expected surge in dengue fever cases this year. They noted three key factors: (i) high Aedes aegypti mosquito population detected in the community; (ii) previously uncommon Dengue virus serotype 3 (DENV-3) circulating; and (iii) sizeable proportion of people still staying in and working from home.
According to the quarterly surveillance data from the Ministry of Health, 3,335 dengue cases (including 7 dengue hemorrhagic fever cases) were notified in the quarter from Jan to Mar 2022, an increase of 279.8% as compared to the previous quarter from Oct to Dec 2021.
There was one reported death due to local dengue infection from Jan – Mar 2022.
Results of positive dengue samples serotyped between Jan and Mar 2022 indicated that DEN-3 accounted for majority of the typed samples, followed by DEN-2 and DEN-4.
Dengue is transmitted to humans through the bite of an infected Aedes mosquito (Aedes aegypti and Aedes albopictus). Dengue fever is not contagious and does not spread directly from person to person. A mosquito is infected when it takes a blood meal from a dengue-infected person. After approximately one week, the mosquito can then transmit the virus to other people they bite.
