On day 1, there were four “confirmed dark cases (other confirmed cases)” in Busan whose source of infection was unknown. After the first confirmed coronavirus in Busan on February 21, the number of ‘other confirmed cases’ during the day was the highest. Meanwhile, usually 1-2 people went out a day.
The Busan City Health Authority said on the day that “9 new corona patients (Busan 297 ~ 305) have occurred.” Among them, 4 people, including Busan No. 299, were “other confirmed cases” whose source of infection was not disclosed. The remaining five were two people who came into contact with a confirmed person in Yeonsan-dong officetel, two people infected with each other, and one person who had contact with a confirmed person in Gangnam-gu, Seoul.
It is the first time since the start of the corona spread in February that there have been another 4 confirmed cases. When 22 confirmed cases came out per day, or when 9 to 14 cases occurred recently, there were no other confirmed cases, or 1 to 2. During last August, six ‘other confirmed cases’ were recorded. According to official statistics, it is within 5% of all confirmed cases. Although the origin of the infection will be revealed through an epidemiological investigation in the future, it is unusual for 6 people to be classified as ‘other confirmed cases’ per day, although 6 people came out in the current state.
The city’s health authorities said: “If there are several four stations not classified as infectious agent, there are many difficulties in epidemiological investigation and the risks are felt in the community.” If there are several four unclassified seasons, there are many difficulties in epidemiological investigation and the danger is felt in the community. ”“ After the holiday season around August 15, there is enough doubt that there has been a silent spread in the community we don’t know. “It is a sittuation”.
Busan No. 298 and No. 303 were suspected of being infected with an officetel meeting in Yeonje-dong, Yeonje-gu, Busan, where eight confirmed cases were confirmed. Number 298 is also known to have visited this officetel as contact for confirmed patient number 288 (officetel visit history). Confirmed person 303 appears to have been infected by contacting confirmed person 292 (officetel visit history). As a result, the number of confirmed cases related to the Yeonsan-dong officetel meeting increased to 10.
The city health official said: “The contact of these confirmed people related to Officetel is currently estimated at around 60, and the test is in progress.” The name has been confirmed. “‘Officetel related infected persons’ has not yet been able to specify the number of participants and contacts of the expected spread of the infection, and there is no CCTV within Officetel, making it difficult to determine the total number of meetings and the degree of contact, so the possibility of a continuous increase cannot be excluded.
The confirmed case of Busan 296, which was determined on the 31st of last month, is also of interest. This confirmed person is a family member of a student from Busan Mechanical Engineering High School (No. 217 in Busan) who tested positive on 17 last month. It was confirmed after two weeks from the date of the decision of Busan Mechanical Engineer No 217. Group infection related to Busan Machinery Technical High School spread from Russian offshore fishing vessel ‘Petr 1’, where a group of crew members have been confirmed since July 23. It means that the “crown of the Russian ships” remains the “10th infection” during the eighth to ninth rounds or more for a month.
