The Korea Centers for Disease Control and Prevention (KCDC) announced on the 22nd that it has confirmed 2225 cases of COVID-19 from major mutated viruses from December 2020 to the last.

Lee Sang-won, head of the Epidemiological Investigation and Analysis Division of the Central Quarantine Countermeasures Headquarters (heavy script) said at a regular briefing on the afternoon of the day that 11,336 genes were analyzed and 2225 (19.6%) of major mutated virus cases were confirmed. Among them, 1886 cases of alpha type (from the UK), 142 cases of beta type (from South Africa), 7 cases of gamma type (from Brazil), and 190 cases of delta type (from India) were explained.

“The government has been monitoring major mutated viruses in Korea since December 2020,” Lee said. “The detection rate is continuously increasing, which is also increasing worldwide.”

He added that the mutant virus is a naturally occurring phenomenon in the course of an infectious disease outbreak. After the government first discovered the UK mutation in the quarantine stage in December 2020, it conducts genetic analysis on potentially dangerous areas or samples in Korea, and foreign importers are at risk based on reports reported to the International Influenza Information Sharing Organization (GISAID). Countries are prioritized and tests are conducted on confirmed patients among inbound travelers. Chairman Lee emphasized that Korea is higher than the World Health Organization (WHO) standard in the proportion of virus genetic analysis. He said, “Korea is conducting genetic analysis on 15.6% of viruses, which is slightly higher than the 5-10% of confirmed cases recommended by the WHO in May as of May.” “The detection rate of major mutated viruses is 39.6%,” he said. said.

It was also explained that the detection rate of major mutated viruses was 39.6% lower than in other countries. UK 98.98%, France 85.98%, USA 67.79%, Canada 47.27%, Japan 51.27%.

Regarding delta-type mutations, which are on the rise globally, the detection rate in Korea was 1.9% as of June, while the detection rate in overseas imports was high at 37.0%. This means that the number of delta mutations among the confirmed cases from overseas is increasing.

In this regard, Chairman Lee emphasized, “We will continue to block foreign imports and monitor virus genes, and we will ensure that vaccinations scheduled for the second half of the year are carried out without any setbacks.”

Meanwhile, according to the Korea Centers for Disease Control and Prevention (KCDC), 261 out of 732 confirmed cases of major mutated viruses were additionally confirmed this week, accounting for 35.7%. By virus type, there were 223 cases of alpha type, 2 cases of beta type, 1 case of gamma type, and 35 cases of delta type. Among them, 34 cases were imported cases, and 227 cases were domestic cases.
