Forty-seven tigers, three lions, and a panther have succumbed to the H5N1 bird flu virus in zoos across southern Vietnam, according to reports from state media. This alarming incident unfolded during August and September at two facilities: the My Quynh Safari Park in Long An province and the Vuon Xoai Zoo located in Dong Nai, not far from Ho Chi Minh City.
The National Centre for Animal Health Diagnosis confirmed the cause of death, attributing it to the “H5N1 type A virus,” as stated by the Vietnam News Agency (VNA). In light of this crisis, both zoos have refrained from providing further comments when approached by the Agence France-Presse (AFP).
Despite the devastating impact on these animals, VNA reported that no staff members who had close contact with the affected animals exhibited any respiratory symptoms.
In the broader context of wildlife conservation, the NGO Education for Nature Vietnam disclosed that, at the end of 2023, there were approximately 385 tigers held in captivity across the country. Of these, around 310 tigers reside in 16 privately owned farms and zoos, while the remainder are cared for in state-run facilities.
The World Health Organization (WHO) has been closely monitoring the situation, noting a rise in reports of lethal outbreaks among mammals caused by influenza viruses, including H5N1, since 2022. The WHO has indicated that H5N1 infections can vary in severity in humans, ranging from mild symptoms to fatal cases. Vietnam reported a human fatality linked to this virus to the WHO in March.
The situation is not confined to Vietnam. In the United States, the U.S. Department of Agriculture has detected bird flu in approximately 200 dairy herds across 14 states this year. The virus has also affected both commercial and backyard flocks, as well as wild bird populations.
