The government is closely monitoring the hantavirus, stressing that Thailand has yet to detect any outbreak. It has intensified screening measures and ongoing risk assessments to ensure public confidence and safety.
On 11 May 2026, Ms. Lalida Pertwiwatthana, Deputy Spokesperson of the Prime Minister's Office, revealed that the government, through the Ministry of Public Health, has been closely tracking the situation. Hantavirus infectious disease. This follows the World Health Organization (WHO) reporting cases linked to a cruise ship in the South Atlantic Ocean. Currently, Thailand has not found any outbreak of this disease and assesses the risk to the general public as low. Nevertheless, surveillance has been intensified both at international disease control checkpoints and within the country’s internal monitoring systems.
The Deputy Spokesperson explained that hantavirus is a communicable disease primarily carried by rodents such as field mice and house mice. Infection usually occurs by inhaling dust contaminated with rodent urine or feces in enclosed spaces. Human-to-human transmission is very rare and limited to certain strains. Early symptoms resemble a common cold, with some cases progressing to respiratory issues. Currently, there are no specific antiviral drugs or vaccines; treatment focuses on symptom relief.
The government has instructed the Department of Disease Control to enhance monitoring of travelers from high-risk areas by coordinating with airlines, ports, and related agencies. Health service providers nationwide have been alerted to increase screening of individuals with a history of rodent exposure. Additionally, the National Communicable Disease Committee has approved the department’s study on classifying hantavirus as a dangerous communicable disease under the Communicable Disease Act B.E. 2558 (2015). Risk assessments are being prepared alongside strengthening surveillance systems and response plans aligned with the situation.
At the same time, the government requests public cooperation to reduce risks from contact with rodents and contaminants by avoiding enclosed spaces where rodents may live. If cleaning such areas is necessary, sweeping or vacuuming should be avoided; instead, disinfectants should be sprayed before cleaning. Maintaining cleanliness at home and workplaces is also advised to prevent rodent breeding sites.
“The government prioritizes close monitoring of emerging diseases. Although Thailand currently has a low risk, preparations in surveillance, screening, and communication have been made to continuously assure and protect public safety,” the spokesperson said.
