Covid-19 sars-cov-2 zoonotic risk from domestic and exotic animals and possible mitigation by mesenchymal stem cell therapy

It is clear that animals can become infected with SARS-CoV-2 as the virus can be found in nasopharyngeal swabs in naturally and experimentally infected animals. These animals were both symptomatic and asymptomatic. It seems clear that the described animals in this manuscript were infected from humans, but animal-animal transmission is also demonstrated. If it is found that these animals can transmit this virus to humans, mesenchymal stem cell therapy may be a tool to reduce both the disease severity in the infected animals and the shedding of the virus and therefore zoonotic risk to humans.
