Dengue fever outbreak in Laos infects hundreds

According to reports, 235 people have been infected with dengue fever and no deaths have been recorded since the beginning of 2017. Out of the country’s 18 provinces, 12 have reported infected people, and 70 people have been recorded in Vientiane, the capital of Laos.


The absence of reports from other areas does not mean that there is no dengue fever transmission there. The risk of exposure will vary from place to place and may be high in many localities.

All travellers to areas where the dengue fever virus is active can reduce their risk of exposure by taking all necessary precautions to avoid mosquito bites. Many persons with dengue fever do not seek medical care and are not reported to health authorities. There may be many more cases in the community than the reports indicate.
