According to the zoo, two of the gorillas had started coughing on Wednesday, following which San Diego Zoo Global initiated the process of testing fecal samples from them for SARS-CoV-2 through the California Animal Health and Food Safety Laboratory System.
The agencies said that both pets had mild respiratory illness and are expected to make a full recovery. COVID19 infections have been reported in very few animals worldwide and mostly in those that had close contact with a person with COVID-19.
The female tiger, named Nadia, is believed to be the first known case of an animal infected with COVID-19 in the US. It is suspected that she contracted the virus from a caretaker who was asymptomatic at that time.
