Thailand’s National Communicable Disease Committee on Friday approved the classification of hantavirus as a “dangerous communicable disease”, prompting stricter surveillance and emergency response measures across the country.
According to the Ministry of Public Health, authorities must now report suspected cases within three hours, begin disease investigations within 12 hours, and enforce a 42-day quarantine for high-risk contacts.
The ministry said hantavirus has become a major global public health concern, with certain strains capable of human-to-human transmission through respiratory droplets. The designation was introduced to strengthen the country’s preparedness and response mechanisms.
An elevated action plan has been activated, focusing on surveillance, laboratory testing, medical treatment, and local-level implementation. Health authorities are also increasing monitoring at international entry points.
Somruek Chungsaman, permanent secretary of the ministry, said the Department of Disease Control is finalising definitions for “Patients Under Investigation” and protocols for immediate domestic investigations. Provincial public health offices and hospitals have been instructed to closely monitor cases, review treatment procedures, and communicate risks to local communities.
He urged people with recent rodent exposure or travel history from high-risk areas to seek immediate medical attention if they develop symptoms such as high fever and breathing difficulties.
Hantaviruses are carried by rodents and can cause severe illness in humans. Infection usually occurs through contact with infected rodents or exposure to their urine, saliva, or droppings. Human-to-human transmission remains rare.
Health officials said infections are most commonly reported in rural areas such as forests, farms, and fields where rodent exposure is more likely. Activities like cleaning rodent-infested buildings can also increase the risk of infection.
