Two migrant fishermen who returned to Taiwan after holidays in their homelands, one from the Philippines and the other from Indonesia,  were diagnosed with dengue fever during preliminary screening tests.

Last Thursday, a Filipino in his 30s who works in Qianzhen district, Kaohsiung, was confirmed as the fourth case this year of dengue fever contracted abroad, The Liberty Times reported.

Upon his arrival at Kaohsiung International Airport on February 28, the Filipino was quickly taken to Kaohsiung Municipal Min-Sheng Hospital under the screening scheme arranged for migrant fishermen. He had a low-grade fever with body temperature recorded at 37.9 degrees Celsius.

Meanwhile, an Indonesian worker who visited his homeland last month and returned to Kaohsiung on March 1 reported feeling unwell with symptoms of dengue fever including fever, headache, muscle pain and cough.

His blood tested positive for dengue in a preliminary analysis, and now the patient is being treated in Kaohsiung Municipal Min-Sheng Hospital in isolation. A detailed test will be conducted later for confirmation of the initial diagnosis.

The Taiwan Centers for Disease Control said officers would continue their efforts in screening, surveillance and control of infectious diseases at the borders.
