A Changhua couple contracted dengue fever while traveling to Phu Quoc Island in Vietnam. The number of cases of overseas immigrants in the county increased to 14 this year.

The Changhua County Health Bureau confirmed today (24th) that a couple from Changhua County participated in a tour group to Phu Quoc Island in Vietnam from September 12th to 15th this year. After returning home, they developed symptoms of headache, fever, and rash on September 19th and 20th. After the examination, they were determined to be confirmed cases of overseas migration. The relevant group members and contacts are under continuous monitoring.

According to statistics from the Changhua County Health Bureau, there have been 14 cases of overseas immigrants in the county this year, including the couple, which doubled compared to 7 cases in the same period last year. The Health Bureau reminds that many countries in Southeast Asia are currently dengue fever endemic areas. People traveling abroad must be more vigilant, take personal anti-mosquito measures, and continue self-monitoring of their health for at least 14 days after returning home.

On August 28 this year (2026), it was reported that a hundred-person Philippine study tour group in Taiwan was infected with dengue fever locally, and 4 people were shot in Changhua. The Health Bureau stated that together with these 4 people and 2 couples this time, there are currently 14 confirmed cases of dengue fever imported from abroad this year in the county.

The Health Bureau stated that dengue fever is mainly transmitted through the bite of vector mosquitoes carrying dengue virus. Southeast Asian countries such as Vietnam, Indonesia, the Philippines, Thailand, Malaysia and Cambodia have hot and humid climates, which are suitable for the growth and reproduction of vector mosquitoes. People must take mosquito protection when traveling to relevant areas, visiting relatives or on official business, and pay attention to their own health for 14 days after returning home.
