The aggregate number of people infected surpassed 1,000 within a month after the emergence of Omicron, a novel mutant strain of COVID-19, in Korea.
The Central Defense Response Headquarters announced that, as of 00:00 on the 1st, an additional 220 cases of Omicron mutation were confirmed, bringing the total number of infected individuals to 1,114.
Five people, including a couple, acquaintances, and two other overseas travelers who returned from a visit to Nigeria on the 1st of the previous month, were the first confirmed cases of Omicron, and the number of infected people exceeded 1,000 within a month.
Among the new infections, 94 were imported from abroad, while 126 were domestic (local infections). 57 of the imported cases, accounting for more than 60%, originated from the United States. The day before, 131 individuals arriving from the United States were confirmed to have been infected with Omicron.
The high number of infections from the United States can be attributed to the fact that the United States has extensive exchanges with Korea and the largest number of people entering the country. Presently, Omicron infection is rapidly spreading in the United States.
Following the United States, the UK reported six cases, followed by three cases each from Brazil and France, two cases each from Nigeria, South Africa, the Dominican Republic, Canada, Kenya, Qatar, the Netherlands, Rwanda, Malaysia, the Maldives, Sudan, Spain, the United Arab Emirates, and Cameroon. Additionally, one case each was reported from Poland, Finland, and the Philippines.
Details regarding the route of infection and the region of occurrence of domestic infections remain unconfirmed.
Since the 30th of the previous month, the rapid PCR (gene amplification) test, capable of confirming Omicron mutation infection within 3 to 4 hours, has been introduced, and the number of infections is increasing at an accelerated rate.
In Korea, the number of infected individuals imported from overseas, as well as those infected within the community whose route of infection is unknown, is rapidly increasing, indicating that Omicron’s emergence as a dominant species is imminent.
Park Young-joon, head of the epidemiological investigation team for the Central Defense Response Headquarters, stated, “We believe that the infection is spreading to some extent within the local community.”
A total of 24 cases of suspected infection and transmission of Omicron were officially confirmed until the previous day.
Of the 1,114 cumulative Omicron infections, 541 were domestically infected, while 573 were imported.

The Spread of Omicron in Korea: A Wake-Up Call for Global Vigilance
As I read through the latest news article, I am struck by the alarming rate at which the Omicron variant of COVID-19 is spreading in Korea. Within a mere month of its emergence, the total number of infected individuals has surpassed 1,000, with an additional 220 cases confirmed recently. This rapid spread is a stark reminder of the need for continued vigilance and cooperation in the fight against the pandemic.
According to the article, the first confirmed cases of Omicron in Korea were five individuals who had traveled to Nigeria, and the virus has since spread rapidly, with both imported and domestic cases contributing to the growing tally. What is particularly noteworthy is the high number of infections originating from the United States, which accounted for more than 60% of the imported cases.
As researchers have noted [[1]], [[2]], the Omicron variant has been the subject of extensive study, with efforts to understand its epidemiological processes and transmission dynamics. Studies have estimated the underlying epidemiological processes of Omicron VOC in South Korea using time-scaled phylodynamic analysis [[1]], [[2]]. Another study has also investigated the incubation period of SARS-CoV-2 Omicron, collecting information on exposure history and symptom onset of 22 Omicron BA.1 cases in South Korea [[3]].
The rapid spread of Omicron in Korea highlights the importance of continued global cooperation and vigilance in the fight against the pandemic. As we have seen time and again, the COVID-19 pandemic knows no borders, and the emergence of new variants is a constant reminder of the need for collective action to mitigate its impact.
In this context, the Korean government’s efforts to reorganize the distance system to combat Omicron and reduce quarantine pass requirements are a step in the right direction. However, it is crucial that these measures are complemented by robust surveillance, testing, and contact tracing to prevent further spread of the virus.
As we navigate this challenging landscape, it is essential that we continue to prioritize evidence-based decision-making and global cooperation to combat the spread of COVID-19. Only through collective action and vigilance can we hope to mitigate the impact of the pandemic and build a safer, healthier future for all.
