SINGAPORE - A 73-year-old woman who stayed at Poh Huat Road West has died from dengue, the Ministry of Health (MOH) and the National Environment Agency (NEA) said in a joint release on Thursday (March 24).

Her condition deteriorated after she was admitted to Tan Tock Seng Hospital on Tuesday (March 22). She is the fourth person reported to have died from dengue this year.

The authorities said her home is located in an active dengue cluster with four cases. The dengue virus is spread by mosquitoes.

Vector control operations to kill mosquitoes and destroy their potential breeding grounds have been carried out, since the authorities were notified of the cluster on March 11.

NEA also conducted multiple rounds of inspections in residential premises and outdoor and common areas in the estate.

MOH and NEA expressed their condolences to the woman's family.

"Residents are urged to cooperate fully and allow NEA officers to inspect their premises for mosquito breeding, and to spray insecticides to kill any infective mosquitoes," the statement said.

On March 11, a 63-year-old woman from Bedok North died from the mosquito-borne virus. The other two casualties this year were a 67-year-old Singaporean man who lived in Toa Payoh, and a 47-year-old man from Marsiling Rise.
