Members of the Gorilla Troop at the San Diego Zoo Safari Park have tested positive for coronavirus, the virus that causes COVID-19. Last Wednesday, January 6, two of the gorillas began coughing and San Diego Zoo Global (SDZG) initiated the process of testing fecal samples from the gorillas through the California Animal Health and Food Safety Laboratory System. On Friday, January 8, the preliminary tests detected the presence of the virus in the gorilla troop. The U.S Department of Agriculture (USDA) National Veterinary Services Laboratories (NVSL) confirmed the positive results today.
The test results confirm the presence of coronavirus in some of the gorillas and does not definitively rule out the presence of the virus in other members of the troop.
“Aside from some congestion and coughing, the gorillas are doing well,” said Lisa Peterson, executive director, San Diego Zoo Safari Park. “The troop remains quarantined together and are eating and drinking. We are hopeful for a full recovery.”
It is suspected the gorillas acquired the infection from an asymptomatic staff member, despite following all recommended precautions including COVID-19 safety protocols from the Centers for Disease Control and Prevention (CDC) and San Diego County Public Health as well as wearing PPE when near the gorillas. Research studies have verified that some non-human primates are susceptible to infection with coronavirus, but this is the first known instance of natural transmission to great apes and it is unknown if they will have any serious reaction.
“For almost one year our team members have been working tirelessly, with the utmost determination to protect each other and the wildlife in our care from this highly contagious virus,” said Peterson. “The safety of our staff and the wildlife in our care remains our number one priority.”
The San Diego Zoo Safari Park, like many public facilities, has been closed to the public since December 6. The primate habitat at the San Diego Zoo Safari Park allow the great apes to be a safe distance from all guests at all times and pose no public health risk.
