Bangkok, Thailand – A chickenpox outbreak has led to urgent measures at Thammasat University’s Rangsit campus, with classes moving fully online from March 3rd to 6th, 2026. The Department of Disease Control (DDC) in Thailand is investigating the situation, tracing cases back to a student camp held in mid-February. This outbreak highlights the ongoing challenges of managing infectious diseases within educational settings and underscores the importance of preventative measures.
The DDC launched an urgent disease investigation after being alerted to the outbreak on March 3rd, 2026. Dr. Montien Kanasawat, the DDC director-general, dispatched an emergency investigation team to the campus on Tuesday, working in collaboration with the Office of Disease Prevention and Control Region 4 and the Pathum Thani Provincial Public Health Office, according to reports.
Student Camp Identified as Potential Source
Initial investigations point to a student camp held between February 13th and 16th, 2026, as a key event in the spread of the virus. Approximately 66 participants, including around 60 students from various provinces, attended the camp. One participant reportedly developed chickenpox symptoms and was asked to leave, but the camp continued. The DDC is actively tracing contacts and assessing the extent of the exposure.
As of early March, approximately 13 university students and 10 school pupils have reported illness and are receiving treatment. The outbreak is currently affecting students in two faculties at the Rangsit campus. The decision to move classes online was made to limit further transmission and protect the wider university community.
Understanding Chickenpox and Prevention
Chickenpox is caused by the varicella-zoster virus and is characterized by an itchy rash with little, fluid-filled blisters. The illness is highly contagious, particularly to individuals who have not been vaccinated or previously had chickenpox. Vejthani International Hospital notes that while chickenpox is less common now due to widespread vaccination, it can still occur, and adults who contract the virus may experience more severe symptoms.
The virus can be spread easily, even before the rash appears, remaining contagious until all blisters have crusted over. Symptoms typically include fever, headache, fatigue, and loss of appetite before the rash develops. The rash itself progresses through stages – bumpy, blistered, and then crusting over – and new bumps can continue to appear for several days.
Broader Health Concerns in Asia
While Thailand addresses this chickenpox outbreak, other parts of Asia are facing different public health concerns. Nikkei Asia reports that several Asian countries are on alert for a potential spread of mpox (monkeypox), with cases recently detected in both Thailand and the Philippines following the World Health Organization’s declaration of a global emergency.
Experts are also warning about the potential threat of mpox in Thailand, urging vigilance as the global situation evolves. The Bangkok Post highlights the need for preparedness in case the current outbreak escalates into a larger pandemic.
The DDC’s investigation at Thammasat University is ongoing, and authorities are working to contain the chickenpox outbreak and prevent further spread. The situation will continue to be monitored closely, and updates will be provided as more information becomes available. The university plans to reassess the situation on March 6th to determine when in-person classes can safely resume.
