The test matches RNA in three locations, and stopped working for the spike gene due to the HV 69–70 deletion—a deletion of the amino acids histidine and valine in positions 69 and 70, respectively [262] —in the spike protein of lineage B.1.1.7. This made preliminary identification easier because it could be better suspected which cases ...
Studies have identified a range of animals—such as cats, ferrets, hamsters, non-human primates, minks, tree shrews, raccoon dogs, fruit bats, and rabbits—that are susceptible and permissive to SARS-CoV-2 infection.
