Yet Another Species Infected by Covid19

Two Hippopotamuses at Antwerp Zoo, in Belgium, have tested positive for Covid19 infections (https://www.theguardian.com/world/2021/dec/05/hippos-test-positive-covid-antwerp-zoo-belgium). These semi-aquatic herbivores presumably caught their viral infections from zoo keepers. The public (even if allowed to visit the zoo) would not get close enough. Fortunately, the animals do not seem to be endangered by the virus.
