Dengue Fever in Laos - Latest Information

Health authorities have expressed concern following reports of 74 deaths and at least 37,700 people infected with the dengue fever virus. Most of the cases have occurred in the capital city, Vientiane, and the southern provinces. In the same time period in 2018, only 15 people died and approximately 5,600 people were infected with the virus.

Advice

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.

Travellers should also be aware that where dengue fever virus is active, there is a possibility in some locations that the chikungunya and Zika viruses may be present also since they are transmitted by the same mosquito that transmits dengue virus.
