Vietnam Zoo's Tigers Die from Bird Flu: What Went Wrong?

In a tragic event at the Vuon Xoai zoo in Vietnam, over a dozen tigers lost their lives due to bird flu. The animals were fed raw chicken bought locally, which carried the virus. The manager, Nguyen Ba Phuc, reported that the tigers died quickly, showing symptoms like weakness and loss of appetite. Tests confirmed they had H5N1, a bird flu strain that has affected various animals worldwide. The virus first appeared in 1959 and has since evolved, affecting different species from birds to sea lions. In cats, it damages blood vessels and can cause seizures leading to death. Around 20 more tigers were isolated for monitoring after this incident. The zoo is home to many animals including lions, bears, and giraffes.

Zoo staff who cared for the infected tigers tested negative for bird flu. Another outbreak in Long An province resulted in the deaths of 27 tigers and 3 lions within a week last September. This highlights the risk of keeping wild animals in captivity, as viruses can spread easily. PETA’s Jason Baker emphasized that such incidents increase the likelihood of human pandemics. Bird flu has caused hundreds of deaths globally, mostly through direct contact with infected birds.
