Another case of dengue fever was confirmed in the southern Taiwan city of Tainan on Tuesday, with the total number of “imported” dengue cases reaching 12 in the city.

The victim is a Vietnamese migrant worker who entered to Taiwan on August 16, according to a statement released by Tainan City’s Department of Health on Thursday.

The man sought medical attention on August 26, ten days after his arrival, due to a high fever of 39 degrees Celsius. He went to a clinic in North District, but was diagnosed with influenza.

Two days later, the man felt worse and visited the doctor again, saying he had pain behind his eyes and muscle pain throughout his body.

A suspected case of imported dengue fever was immediately filed to the Department of Health and a laboratory test for the disease was quickly run for the Vietnamese national.

By September 5, the suspected case was confirmed positive, China Daily News reported on Friday.

Tainan City Government has stepped up efforts to eliminate mosquitos, which carry the disease, in Chengde Village in North District, where the Vietnamese man resides.

Anyone who has symptoms of dengue – such as fever, headache, pain behind the eyes, muscle and joint pain, loss of appetite, nausea or a rash – should seek medical advice promptly.
