Omicron’s domestic spread is strong.

In particular, the possibility of airborne transmission is emerging as cases of infection have been confirmed even through brief contact at restaurants.

Within a week of the confirmation of the Omicron mutation in Korea, the number of confirmed cases of Omicron infection has risen to 36.

It spread from the pastor’s couple, the first infected, to a man in his 30s, an acquaintance, and then to the man’s family and acquaintances.

The risk of spread within the region is increasing.

As three foreign students attending Seoul National University, Kyunghee University and Hankuk University of Foreign Studies were confirmed to have mutated infection, the first confirmed case of Omicron was confirmed in Seoul.

After Incheon, Gyeonggi-do, and Chungbuk, the number of Omicron infected areas increased to four in all, including Seoul.

The quarantine authorities are paying attention to the rapid spread of Omicron.

In particular, there are growing concerns about Omicron’s rapid propagation power as cases that spread through a restaurant rather than inside a church appear.

The owner of a restaurant where the mother-in-law of a man in his 30s who was infected by the pastor and his wife ate was infected with Omicron, because the only contact was to deliver food and pay.

Overseas, reports of rapid transmission are continuing, such as the infection reproduction index of the Omicron mutation is 2 or higher and the infectivity is 3-6 times higher than that of the Delta mutation.

In Hong Kong, a study found that travelers who were quarantined in other rooms were more likely to have contracted omicron and airborne transmission when they opened a door to receive food.

The quarantine authorities explained that in an enclosed space, the length of stay is more important than the time of direct contact.

However, he said that it is difficult to accurately determine the propagation power of microns only in this case, and he said that he is investigating the possibility that the propagation power is higher than the delta variation.
