The AVMA website reported that a dog and cat from the same household in Brazos County yielded SARS-CoV-2 variant B.1.1.7. This variant is now circulating in the U.S. presumably after either introduction from the U.K. or by spontaneous mutation in the U.S. The infections were initially detected on surveillance, but subsequently both animals demonstrated mild respiratory signs.
In an unrelated event, two Malayan tigers at the Norfolk, VA. Zoo tested positive for SARS-CoV-2 following development of mild respiratory signs consistent with previous cases reported in large cats housed in U.S. zoologic gardens. Both animals are expected to recover and other large felines at the facility are asymptomatic. There is no indication of how the two tigers and possibly a third were infected or the strain of SARS-CoV-2.
