I find the following features of SARS cov2 somewhat worrying. Mutations, infectivity of asymptomatic carriers, prolonged asymptomatic harboring of virus and transmission to animals. The transmission to mink is well known, but more recently 8 Gorillas have become infected in St Diego’s Safari Park:
“LOS ANGELES (Reuters) – As many as eight gorillas at the San Diego Zoo Safari Park are presumed to have contracted COVID-19 from a human handler after one of the animals tested positive, marking the first known transmission of the virus to apes, zoo officials said on Monday.”
The handler was asymptomatic and observed appropriate measures according to the article.
The prolonged transmissibility has been highlighted by ET in the cases he describes from his Island residence.
