Taipei sees first cluster infection of dengue fever in 5 years

A husband and wife who live in Neihu District Taipei have been diagnosed as the seventh and eighth confirmed indigenous cases of dengue fever in Taiwan since the start of summer, the Centers for Disease Control (CDC) said on Sunday.

The CDC also described them as cluster infection cases, saying the couple had not been abroad during the incubation period of the virus.

The couple lives some 24 meters from a 56-year-old woman who had been confirmed to have dengue fever on Nov. 24, and the couple and woman were active in the same neighborhood and evening farmers market.

Another person living with the couple is OK for now, but the CDC has started dengue fever containment measurements in the area, CDC Deputy Director-General Chuang Jen-hsiang (莊人祥) said.

Chou Jih-haw (周志浩), CDC director-general, led health inspection personnel to inspect the neighborhood within a 150-meter radius around the houses.

Chou found mosquito larva could live in still water in portable garages and discarded tires and plastic containers nearby and called on residents to clean the environment.

Chuang said the neighborhood is populous and needed to be observed for a week to see if there will be a new wave of infection. He said the neighborhood monitoring will last until Dec. 21.

The last time Taipei had a cluster infection of dengue fever was in Shilin District in 2011, when there were 20 dengue fever cases.

Since May 1, eight indigenous cases of dengue fever have been reported in Taiwan — two each in Tainan and Kaohsiung, one in Pingtung County and three in Taipei.

Among the 378 total number of reported dengue fever cases in Taiwan so far this year, 331 have been confirmed as imported, mostly from Indonesia and the Philippines. The other 39 cases have yet to be determined.
