Thailand Mandates 42-Day Quarantine in Response to Hantavirus Concerns

Thailand has officially classified hantavirus as a dangerous infectious disease, even though no confirmed cases have been reported in the country so far. This policy also places hantavirus as the 14th disease on the list of dangerous infectious diseases based on the Communicable Disease Act 2015.

According to the Bangkok Post, with this status, all individuals with high-risk contact with infected patients are required to undergo a 42-day quarantine from the last exposure.

This policy also strengthens public health prevention and preparedness measures amid increasing global awareness of the infectious disease, including after international attention on the outbreak that occurred on a cruise ship, the MV Hondius.

The Permanent Secretary of the Thai Ministry of Public Health, Dr. Somruek Chungsaman, explained that even though Thailand has not recorded any confirmed cases, this step is intended to strengthen prevention and preparedness.

The decision was made after experts assessed that the virus poses a serious risk, including respiratory and kidney syndromes, and can spread through airborne droplets, with some strains potentially transmissible between humans.

Based on the new classification, suspected cases must be reported within three hours and investigated within 12 hours. Individuals with high-risk contact must undergo a 42-day quarantine from the last exposure.

Dr. Somruek said this step allows for rapid legal action, including isolation and quarantine orders, to strengthen surveillance and control.

Hantavirus disease is defined based on symptoms including fever above 38C, chills, muscle aches, headache, fatigue, and gastrointestinal illnesses such as nausea, vomiting, or diarrhea. Severe cases can develop into respiratory failure, fluid accumulation in the lungs, shock, low blood pressure, kidney failure, and death.
