The study found that in the first and second wave of new coronary pneumonia in Hong Kong, bars and karaokes caused the most transmission. 91 cases; the bar group is the longest transmission chain, extending to 30 other groups within 26 days, causing transmission in 7 environments.

The research team believes that most of the customers who spend time in entertainment venues do not know each other. Coupled with the long stay, it is easy to cause group-to-group communication and the ability to form a transmission chain is higher than that of restaurants.

The team believes that some of the hotel's functions have been changed from accommodation to "staycation" and other social venues, which is more likely to become the fourth wave of outbreak venues.
