Taipei, The second indigenous dengue fever case of this year in Taiwan has been confirmed, the Centers for Disease Control reported Wednesday.
A student in Xinzhuang, New Taipei came down with a fever, nausea, vomiting and aches and pains July 7 and he was hospitalized the next day before being sent home.
The patient sought medical treatment again July 9 after suffering from diarrhea and after a blood test, was confirmed July 10 to have dengue virus type 2 (DENV-2) infection. He was then put into isolation.
The patient did not travel overseas during the incubation period prior to the onset of his disease, CDC Deputy Director-General Philip Lo (???) said, but during the period, he stayed July 3-6 in Kaohsiung with his family before traveling to Taitung.
Health authorities are tracing the possible source of the infection, according to Lo.
It was thought that the patient's diarrhea was related to dengue fever infection, Lo said, but a local survey found that only about 33 percent of patients infected with DENV-2 during a 2015 dengue outbreak in Taiwan suffered from diarrhea.
As of July 10, two indigenous dengue fever cases had been reported in Taiwan this year, according to CDC statistics.
A Kaohsiung man in his 30s became the first reported indigenous dengue fever case this year, the CDC reported earlier this month.
The man was confirmed to have dengue virus type 3 (DENV-3) infection and has been kept in isolation since July 1, according to the CDC.
In addition, there have been 103 imported cases of dengue fever so far this year, the second-lowest during the same period between 2014 and 2018, with 95, 120, 147, 124 cases reported, respectively, in the same period of the previous years, according to CDC data.
The CDC reminded residents to take precautionary measures when traveling to dengue-endemic countries, and to seek treatment as soon as possible when symptoms of dengue fever, including fever, headaches, severe muscle and joint pain, eye socket pain, and skin rash, become apparent.
