The new crown pneumonia epidemic in Hong Kong has repeated. The 27-year-old male ground worker who was diagnosed with the Delta variant virus recently worked part-time in the service office of Suntec Plaza, Tai Po. A 24-year-old female colleague of the service office was diagnosed yesterday (27th) and detected the L452R virus strain. .
No other cases have been found at the residence of the two.
Associate Professor Hsiao Jie-hang of the Department of Medical Technology and Informatics of PolyU stated on a TV program in Hong Kong and Taiwan this morning (28th) that the incubation period of the variant virus is 3 days on average, but it can be as long as 21 days. Therefore, the incubation period of 11 days for male ground crews is not too long.
He also said that the high viral load of patients with Delta variant virus can be maintained for 18 days, increasing the risk of spreading in the community.
Xiao Jieheng, associate professor of the Department of Medical Technology and Informatics, said that the team had previously sequenced the case of a 27-year-old male ground worker and compared it with the case obtained earlier. It was found that the virus gene was similar to the case of the Indian domestic helper who arrived in Hong Kong recently. At the airport sampling center on the same day.
Xiao Jieheng believes that it is impossible to completely rule out male ground staff from being infected in the community at present, but scientific evidence can almost confirm that he was infected while working at the airport. The route of infection is likely to be a collection center. It is estimated that direct transmission may occur at that time, or through printing. The servants contaminated tables and chairs and other facilities, and touched the mouth and nose with their hands without disinfection after the ground crew touched them.
The incubation period of the mutant virus is 3 days on average, and the ground crews did not develop symptoms until 11 days after the arrival of the Indian domestic helper.
Xiao Jieheng emphasized that the 3-day incubation period is only an average number, and it may happen as long as 21 days, so 11 days is not too long.
He also said that the CT value of ground crew is about 15, which means that the virus load is high, while the high virus load of Delta variant virus patients can be maintained for a long time, up to 18 days, which increases the risk of spreading in the community.
He suggested that people who are compulsory for testing, such as the patient’s neighbors and colleagues, should continue to review the case to avoid "missing" the case; and the contact time between the customer service center and the public should not be long, and masks should be worn during the period, and the risk should not be high.
