COVID testing from stool samples in the Prague zoo showed two lions and a western gorilla have contracted COVID-19, but their symptoms have been very mild so far, zoo head Miroslav Bobek told iRozhlas. Further testing will follow. Zoos are currently closed over the coronavirus epidemic in the Czech Republic. In the lions, the symptoms manifest with cold, muffled coughs, while in the gorilla, called Richard, a loss of appetite and fatigue occurred, Bobek said. In cooperation with a veterinary authority, the zoo will gradually test further animals, too. "The sequencing of the samples will be conducted, too, so that we know what coronavirus variant it is," he added. The infected animals are monitored by their keepers and will receive symptomatic treatment if needed. Prague zoo staff is in touch with experts from other gardens that experience COVID in animals.
