Thai Health Authorities Monitor Tick-Borne Viral Fever
The Department of Disease Control is monitoring cases of a tick-borne viral infection characterized by high fever and low platelet counts.
The Department of Disease Control (DDC) in Thailand has issued a notice regarding the surveillance of a viral infection transmitted by ticks, which causes high fever and low platelet counts. According to Khaosod Online, this emerging disease can lead to severe symptoms, including vomiting, diarrhea, hepatitis, and potential organ failure, with a mortality rate estimated between 10% and 30%.
Since the first case was identified in 2019, Thailand has recorded a total of six cases as of June 2025. These cases were reported in Bangkok (2), Phetchabun (2), Nakhon Pathom (1), and Chachoengsao (1). The virus is primarily transmitted by ticks, but transmission can also occur through contact with infected animals or human-to-human contact via bodily fluids.
For residents and travelers, the DDC highlights that Thailand’s environment remains conducive to tick breeding. Risk factors include close contact with pets that may carry ticks, the importation of animals from abroad, and travel to endemic areas. While the DDC is actively monitoring the situation to prevent further spread, the public is advised to be aware of these environmental risks. It remains to be confirmed how the authorities will further refine their containment strategies as they continue to track potential new cases across the country.
