On Sept. 17, 2021, Zoo Atlanta reported that of the 20 gorillas at the Zoo, 18 showed clinical signs consistent with SARS-CoV-2 infection and nine received positive results. For the most part, the clinical signs have been mild to moderate, only two gorillas remain symptomatic.

Clinical signs included sneezing, nasal discharge, coughing, selective and reduced appetite, and in some individuals, subdued behavior. In addition to close monitoring and providing supportive care such as providing extra Vitamin C, our team’s primary goals are ensuring that the gorillas all remain well hydrated by providing them with additional fluids by mouth, as well as monitoring them carefully to ensure that each is eating and receiving enough calories.

The orangutans, lions, tigers, and clouded leopard – species known to be susceptible to SARS-CoV-2 – had been vaccinated. As the gorillas recover, they were also vaccinated.
