Outbreak of Virus Claims Lives of 72 Captive Tigers in Thailand

In February 2026, a highly contagious virus is believed to have led to the deaths of 72 captive tigers in Chiang Mai, northern Thailand. The outbreak has prompted officials to take urgent measures, including disinfecting enclosures and preparing to vaccinate the surviving animals. The specific cause of the fatalities remains under investigation, but initial reports suggest that the tigers were infected with feline panleukopenia.

This incident is not the first of its kind in Thailand. Previous outbreaks have seen significant tiger fatalities, including a 2004 incident in Sriracha Tiger Zoo where 147 tigers died or were euthanized due to bird flu. In 2024, 47 tigers and three leopards died in Vietnam from a similar outbreak linked to avian influenza. These historical precedents highlight the vulnerability of captive tigers to infectious diseases, often exacerbated by their dietary practices.

Officials are currently focused on containing the outbreak and preventing further losses. Somchuan Ratanamungklanon emphasized the difficulty in early detection of illness in tigers, stating, “By the time we notice that something is wrong, the illness may already be advanced.” The Department of Livestock Development is working closely with local wildlife authorities to manage the situation.

There are concerns regarding the management of captive wildlife in Thailand, particularly in facilities like Tiger Kingdom Chiang Mai, which allows close interactions between visitors and tigers. Critics argue that such practices may contribute to stress and health issues among the animals, making them more susceptible to disease outbreaks.

The Guardian

While the Department of Livestock Development has identified feline panleukopenia as a potential cause, the exact circumstances leading to the outbreak remain unclear. There is also a lack of information regarding the vaccination strategy for the surviving tigers and the measures being implemented to prevent future outbreaks.

Authorities are expected to continue their efforts in vaccination and containment, while further investigations into the outbreak's origins and management practices at Tiger Kingdom Chiang Mai are anticipated. The situation remains fluid as officials work to safeguard the health of the remaining tigers.
