Hong Kong’s 42-day streak of zero untraceable Covid-19 infections ended on June 5, when a 17-year-old girl tested positive for the Alpha variant – first identified in the UK. Her mother and her 20-year-old sister were also confirmed infected later.

The center said health officials, together with experts and representatives of relevant departments, yesterday conducted an inspection at the girl’s Tin Shui Wai home, a pet shop and a unit at Tak Wing Industrial Building where the patients had stayed, collecting more than 60 environmental samples.

It was said that an environmental sample from the packaging surface of a prepackaged frozen food from the girl’s home was found to be positive for COVID-19.

According to local reports, the sample was said to be taken from the package of a frozen crocodile meat from Thailand.

“Epidemiological investigations and contact tracing of the case are continuing,” said a spokesman from the Department of Health.

Meanwhile, the center was notified by the health authority of Guangdong Province of a confirmed case in the Mainland last night, which involved a 38-year-old female in Huizhou, Guangdong Province.

“The case was a local confirmed case as announced by the CHP on February 17. She had recovered and was discharged from hospital on February 21 after treatment,” said the CHP.

“After returning to the Mainland via the Shenzhen Bay Port on May 31, she tested positive for COVID-19 during quarantine in the Mainland. The CHP is following up the case with the health authority of Guangdong Province, and the epidemiological investigations of the case are ongoing,” the CHP added.

This marks the eighth consecutive day that the city has recorded zero local Covid-19 infections.

The two imported patients were returnees from Indonesia, of which one had developed symptoms yesterday.
