The government has said that tigers must be observed for symptoms consistent with COVID-19 such as respiratory signs of nasal discharge, coughing and laboured breathing through direct observation and camera trap images after one in New York's Bronx zoo tested positive.

"Diligence needs to be exercised while handling post mortem cases to record location, age and sex of the animal while collecting samples for Corona virus diagnosis in consultation with the State Veterinary officials while safeguarding oneself through appropriate Personal Protective Equipment (PPE)," the government has written in a letter to wildlife wardens.

In another letter, the government has said that the United States Department of Agriculture's National Veterinary Services Laboratories has confirmed the presence of COVID-19 in tiger housed in Bronx Zoo, New York, and therefore, all zoo personnel should remain in high alert.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
