The latest outbreak took place at the Arignar Anna Zoological Park, also known as the Vandalur Zoo, in the southeastern city of Chennai, the Tamil Nadu state government said in a news release.
A number of Asiatic lions, an endangered species numbering only in the hundreds, had shown symptoms of the disease in the zoo. 목요일에, a symptomatic 9-year-old lioness named Neela died. It remains unclear whether Covid-19 was the direct cause of the animal’s death.
Zoo officials and a team of vets immediately quarantined all the lions and started treating them with antibiotics. They have taken samples from the lions, tigers, and other large mammals to send for testing, hoping that genetic sequencing can reveal which strain of the virus infected the lions.
The chief minister of Tamil Nadu, 미디엄. 케이. Stalin, visited the zoo on Sunday to review the situation with a number of other ministers and wildlife authorities. Stalin ordered officials to ensure all zoo staff and animal handlers received vaccinations, 그리고 “provide the best treatment to infected lions,” said the release.
The outbreak follows eight positive cases in March among lions at a Hyderabad zoo. Similar outbreaks have also been reported in the lion enclosures of zoos and safaris in Jaipur and Etawah, said the news release. As a precautionary measure, Tamil Nadu closed its zoos to visitors on April 20.

The news sparked worry among zoologists — after word spread of the Bronx Zoo infections, India’s National Tiger Conservation Authority ordered all tiger reserves in the country to observe their tigers for symptoms, and to ensure all animal handlers were Covid-negative.

“It’s probably not a coincidence that in India, where you have high numbers of cases, that transmission to animals is happening as a direct consequence,” 그는 말했다. “The more cases in humans, the higher the likelihood that animals, including zoo animals, are getting infected.”
Felines like lions and tigers are particularly vulnerable to severe disease, 그는 덧붙였다. While animals like minks and ferrets may be more susceptible to infection, they generally don’t develop severe clinical symptoms — whereas the feline family, which includes domestic cats, “can succumb to the disease, which can make them really sick.”

There are only 523 known individuals left, according to the WWF — and they face widespread threats of poaching, habitat fragmentation, and human activities like wildlife tourism.
The zoo outbreaks “just highlight that humans can transmit pathogens to animals, not only the other way around,” said Osterrieder, pointing to diseases introduced by humans that now threaten mountain gorilla species. “We always have to be mindful of that.”
