Bangkok: Thailand has not yet experienced an outbreak of Hantavirus, but the government is closely monitoring the situation and will continue to enhance screening and risk assessment measures.
According to Thai News Agency, Ms. Lalida Periswiwatana, Deputy Spokesperson for the Prime Minister's Office, stated that the government, through the Ministry of Public Health, is closely monitoring the Hantavirus situation following a report from the World Health Organization about infections linked to a cruise ship in the South Atlantic Ocean. Although Thailand has not experienced an outbreak, the risk to the general public is considered low. Surveillance has been intensified at international disease control checkpoints and within the domestic surveillance system.
Ms. Lalida explained that Hantavirus disease is primarily transmitted by rodents such as field rats and house rats. Infection typically occurs through inhaling dust contaminated with rat urine or feces in confined spaces. Human-to-human transmission is rare and limited to certain strains. Symptoms initially resemble a common cold, with some individuals developing respiratory problems. Currently, there is no specific antiviral drug or vaccine available; treatment remains symptomatic.
The government has directed the Department of Disease Control to increase surveillance of travelers from high-risk areas by coordinating information with airlines, ports, and relevant agencies. Public health facilities nationwide have been alerted to enhance disease screening for individuals with a history of contact with rodents. Additionally, the National Communicable Disease Committee has approved a study by the Department of Disease Control on the appropriateness of designating Hantavirus infection as a dangerous communicable disease under the Communicable Diseases Act B.E. 2558 (2015). A risk assessment, preparation of a surveillance system, and development of response guidelines are also underway.
The government is urging public cooperation in reducing the risk of contact with rodents by avoiding confined spaces that may harbor rats. If cleaning at-risk areas is necessary, sweeping or vacuuming should be avoided, and disinfectant should be sprayed prior to cleaning. Maintaining cleanliness in homes and workplaces is essential to prevent them from becoming breeding grounds for rats.
"The government places great importance on closely monitoring emerging infectious diseases. Although Thailand currently has a low risk, we have prepared surveillance, screening, and communication systems to continuously ensure the confidence and safety of the public," Ms. Lalida emphasized.
