Coronavirus tests will be carried out on cats and dogs if they show symptoms in South Korea. The pets will be tested for Covid-19 if they come into contact with someone who has the virus.The move comes as experts in the UK warned pets should be vaccinated.Last week it was reported in an editorial for the journal Virulence that continued evolution of the virus in animals followed by transmission to humans “poses a significant long-term risk to public health”.“It is not unthinkable that vaccination of some domesticated animal species might… be necessary to curb the spread of the infection,” researchers said.If a pet tests positive for coronavirus its owner must also self-isolate, according to the new regulations in South Korea.
