Dengue fever in Thailand (update)

Dengue fever outbreaks in northern Thailand appear to be more severe than elsewhere. In Chiang Rai Province, the total number of dengue fever cases has reached 2,885 with about half the cases occurring in Chiang Rai City. There have been 3 deaths. The most affected districts include Mae Sai, Muang and Wiang Pa Pao. In adjacent Lampang province, the accumulated number of dengue fever cases is 1,239 so far, 16 times higher than last year. The most affected districts include Muang, Mae Moh, Koh Kha, and Ngao districts.

There may be many more unreported cases since counting and reporting may be hampered by lack of local access to health care, and many persons with mild illness may not seek health care. Travellers to areas where the dengue fever virus is active can reduce their risk of exposure to dengue fever virus by taking all necessary precautions to avoid mosquito bites.
