The recent deaths of 72 tigers across two tourist parks in Thailand have led to calls for a comprehensive investigation into the cause of the outbreak. Authorities confirmed that the tigers, which died between February 8 and 18 in the Chiang Mai province, did not succumb to bird flu as initially feared. Instead, autopsies revealed that the tigers were infected with canine distemper virus (CDV) along with traces of bacterial infection, sparking concerns among wildlife experts regarding the origins and implications of such a virus affecting large cat populations.

Officials from the Chiang Mai regional livestock office have assured the public that the virus does not pose a health risk to humans, alleviating fears of a zoonotic spillover. However, veterinarian Visit Arsaithamkul emphasized that the origin of the infection remains unclear, highlighting the need for a thorough investigation into the conditions that led to the spread of the virus in the populated tourist areas. Given the high profile nature of these parks which attract many visitors, understanding the causes of these fatalities is crucial to ensure the safety and health of both animals and human visitors.

This incident underscores the broader challenges faced in wildlife conservation and the monitoring of animal health in densely populated and commercially popular regions. The call for a detailed inquiry reflects growing concerns over how diseases might emerge in wildlife populations and potentially affect the ecosystems as a whole, especially in light of past experiences with zoonotic diseases. Stakeholders in the region are now calling for heightened surveillance and better veterinary practices to prevent similar occurrences in the future.
