Hong Kong officials confirmed that two new locally transmitted coronavirus cases have been recorded in the city, for the first time in 22 days.
"After 22 days of no locally transmitted coronavirus, we have the first today, we are all very concerned," Dr. Chui Tak-yi of Hong Kong's Food and Health Bureau told a news conference Wednesday.
The two cases are a 66-year old grandmother and her five-year old granddaughter who do not live together.
Health officials are tracing their close contacts. The pair's neighbors, along with the students and teachers at the five-year-old's tutorial center, will be tested for Covid-19, said Dr. Chuang Shuk Kwan of the Hong Kong Department of Health.
Chuang warned that the new cases showed an “invisible transmission chain,” and added that officials would not rule out the possibility of future locally-transmitted cases and a community outbreak.
Officials also confirmed one new imported case from Pakistan. The individual initially tested negative upon arrival in Hong Kong on May 8 but subsequently tested positive on Wednesday while in quarantine.
Hong Kong now has 1,051 confirmed cases of the novel coronavirus including four deaths.
