A pet dog was quarantined at an animal centre in Hong Kong after it tested positive to low levels of the new coronavirus, officials said Friday, in the first such case in the city.

The canine, which belongs to a 60-year-old woman infected with the virus, has no “relevant symptoms”, the Agriculture, Fisheries and Conservation Department said.

But “nasal and oral cavity samples were tested weak positive to COVID-19 virus,” a spokesman said, without explaining why they tested the animal in the first place.
