HUMAN TO ANIMAL TRANSMISSION OF CORONAVIRUS

A Malayan tiger at New York’s Bronx Zoo has been infected with the COVID 19. Four-year-old Nadia is believed to have caught the virus from a zoo employee, who had not shown symptoms.





About:

  1. The virus came from an animal source and mutated; humans have since been infecting humans.

  2. It is theoretically possible for the virus to mutate again to survive in certain species after being transmitted by humans. The Bronx Zoo case suggests an employee spread the virus to the tiger.

  3. There may be a possible explanation why felines are more susceptible. SARS-CoV2 infects respiratory cells after entering through a protein, which lies on the surface of the cells. Called ACE2, the protein in felines resembles ACE2 in humans.

  4. As it is, cats are susceptible to feline coronavirus, which is common but generally asymptomatic, although it can cause mild diarrhoea.
