Bird flu has taken a devastating toll on Vietnam’s captive wildlife, with an outbreak claiming the lives of 47 tigers across two zoos in southern Vietnam.
This tragic incident has raised alarm among conservationists and health officials, who are closely monitoring the spread of the virus and its impact on both animals and humans.
The bird flu outbreak, which occurred in August and September of 2024, not only affected the tigers but also claimed the lives of three lions and a panther.
The H5N1 bird flu virus has long been recognized as a significant threat to both animals and humans. While it is typically associated with poultry, the recent outbreak has demonstrated its deadly potential in other species, including large carnivores. The bird flu outbreak that killed 47 tigers is a stark reminder of the virus’s wide-reaching consequences.
Outbreak in Southern Vietnam: Zoos Affected by Bird Flu
The outbreak began at two prominent zoos in southern Vietnam: the My Quynh safari park in Long An province and the Mango Garden Resort in Dong Nai province.

The first zoo to report fatalities was My Quynh, where 27 tigers, three lions, and a panther died in the span of just two months. According to reports from the Vietnam News Agency (VNA), the animals succumbed to the H5N1 bird flu virus, confirmed by the National Centre for Animal Health Diagnosis.

While the zoo staff closely working with the infected animals showed no signs of respiratory symptoms, the deadly virus caused widespread loss among the zoo’s tiger population. Shortly after, Mango Garden Resort reported the death of 20 tigers and one leopard.
On September 8, four tigers and one leopard died unexpectedly, marking the start of the outbreak at the resort. Over the following days, more tigers at Mango Garden fell ill, exhibiting symptoms such as loss of appetite, fever, and difficulty moving.
The connection between bird flu and these sudden deaths has raised concerns over how the virus was transmitted to the tigers. Investigations have suggested that the tigers at Mango Garden Resort were fed contaminated poultry, as they were given chicken shortly before falling ill.
This points to the possibility that the virus was passed to the tigers through the infected meat, a theory that authorities are now investigating to prevent further spread of the disease.
Impact of Bird Flu on Tigers and Wildlife Conservation
The bird flu outbreak that killed 47 tigers is a severe blow to wildlife conservation efforts in Vietnam. As an endangered species, tigers are already under threat due to habitat loss, poaching, and illegal wildlife trade.
With only 385 tigers in captivity across the country, the loss of nearly 50 individuals is a significant setback. According to Education for Nature Vietnam, around 310 of these tigers are housed in privately owned farms and zoos, while the remainder reside in state-owned facilities.
The tigers at both zoos were part of breeding and conservation programs aimed at ensuring the survival of the species. However, the sudden outbreak of bird flu has disrupted these efforts and resulted in the destruction of many valuable animals.
In Dong Nai province, authorities made the difficult decision to dispose of the 20 tigers and one leopard that died from the virus, overseeing their destruction on-site to prevent further spread of the infection.
Bird flu outbreaks are not uncommon in Vietnam, a country that has dealt with avian influenza in poultry for years. However, this particular outbreak highlights the risk posed to non-avian species, including large mammals like tigers and lions.
While previous outbreaks have predominantly affected poultry, this incident underscores the need for stricter biosecurity measures in zoos and wildlife parks to protect endangered animals from future infections.
Human Health Risks and the Spread of Bird Flu
While the bird flu outbreak in Vietnam has not yet resulted in human fatalities, it serves as a reminder of the potential risks the virus poses to humans.
In March 2024, Vietnam reported a fatality linked to the H5N1 bird flu virus. A 21-year-old college student died after contracting the virus, reportedly after trapping wild birds near his home.
Although no sick or dead poultry were found in the vicinity, this case highlights the possibility of bird flu being transmitted from wild birds to humans.
The World Health Organization (WHO) has issued warnings about the dangers of consuming raw or undercooked meat and eggs from regions affected by avian influenza outbreaks.
Although there have been no human cases directly connected to the recent bird flu outbreak that killed 47 tigers, the risk of transmission to humans remains a concern.
Bird flu is known to mutate and adapt, and while the current strain affecting animals in Vietnam has not yet caused widespread human infections, the potential for the virus to jump species remains.
The WHO continues to monitor the situation closely, advising the public to take precautions when handling poultry or consuming animal products in affected regions.
The bird flu outbreak in Vietnam that claimed the lives of 47 tigers serves as a sobering reminder of the devastating impact that zoonotic diseases can have on both wildlife and humans.
The spread of the virus to captive tigers in two zoos underscores the need for vigilance in preventing future outbreaks and safeguarding endangered species from infectious diseases.
Bird flu, typically associated with poultry, has demonstrated its ability to affect a wide range of species, and this recent outbreak is a tragic example of its reach.
As authorities work to trace the source of the infected poultry and prevent further spread, the incident highlights the importance of biosecurity measures in zoos and wildlife parks.
The loss of so many tigers to bird flu is a significant setback for wildlife conservation efforts in Vietnam, but it also serves as a wake-up call for the need to improve disease prevention and control measures in captive animal populations.
The focus now is on preventing further outbreaks and ensuring that the remaining tigers and other animals in Vietnam’s zoos are protected from future infections. The bird flu outbreak has reminded us of the delicate balance between human activity, wildlife, and the spread of zoonotic diseases.
let’s enjoy few years on earth with peace and happiness….✍🏼🙏
