![]() Some animals which were only thought to have been susceptible at low levels were later found to have experienced higher levels of infection than previously realized, either due to viral mutations or improved surveillance technology. ![]() ![]() Mice were initially unsusceptible but researchers showed that a type of mutation (called aromatic substitution in position 501 or position 498 but not both) in the SARS-CoV-2 virus spike protein can mouse-adapt the novel Coronavirus. According to the US Centers for Disease Control and Prevention, the risk of transmission from animals to humans and vice versa is considerably low but further studies are yet to be conducted. The virus has also been detected in wild animals.Ĭats, dogs, ferrets, fruit bats, gorillas, pangolins, hamsters, mink, sea otters, pumas, snow leopards, tigers, lions, hyenas, hippos, giraffes, tree shrews and whitetail deer can be infected with and have tested positive at least once for the virus. There have been several cases of zoo animals testing positive for the virus, and some became sick. Cases Ī small number of pet animals have been infected. SARS-CoV-2 is believed to have zoonotic origins and has close genetic similarity to bat coronaviruses, suggesting it emerged from a bat-borne virus. ![]() Main article: Investigations into the origin of COVID-19 ![]()
