Everyday Infections, Asymptomatic Young Adults, Nationwide Sporadic Cases... Shaken 'Saenghwal Bangyeok'

Half of the Population Infected in the Capital Area
Wide Movement Radius Leads to Simultaneous Outbreaks
Targeted Quarantine in Specific Areas Becomes Difficult

[Asia Economy Reporter Cho Hyun-ui] As the third wave of the novel coronavirus infection (COVID-19) in South Korea enters a full-scale spread, the situation has reverted to the level of the first wave that occurred mainly in Daegu and Gyeongbuk during February and March.

Although the number of confirmed cases has not yet reached the peak of 909 cases per day seen in the first wave, health authorities are tightening their vigilance. This is because sporadic infections are occurring among unspecified many people during daily life, and confirmed cases are emerging nationwide, especially centered in the Seoul metropolitan area. Moreover, the speed of contact tracing is not keeping up with the spread of COVID-19, raising concerns that new confirmed cases will increase further.

According to the Central Disease Control Headquarters, as of midnight on the 27th, 569 new confirmed cases were recorded. This marks the second consecutive day with over 500 cases, following 583 cases the previous day. It is the first time in about nine months since early March, when the first wave was at its peak, that the daily new confirmed cases have exceeded 500 for two consecutive days.

The third wave is characterized by spreading in various aspects of daily life, mainly among the young population who move frequently in the densely populated Seoul metropolitan area. In fact, among the new confirmed cases on that day, 337 cases occurred in the metropolitan area, accounting for 64.2% of all regional cases. The government views this wave as more precarious than the first wave or the second wave triggered by the August rallies in downtown Seoul, due to more risk factors than before.

Increased indoor activities in winter
Neglect of 3Cs and mask-wearing
Rise in cluster infections among family and acquaintances

First, the spread is intensifying mainly in the Seoul metropolitan area, which has a population more than five times larger than Daegu and Gyeongbuk. The population of the metropolitan area, including Seoul, Gyeonggi, and Incheon, is about 26 million, more than five times the population of Daegu and Gyeongbuk (about 5 million), accounting for nearly half of the total population. The population density is high, and the volume of movement is much greater.

During the first wave, COVID-19 spread mainly within specific groups in specific regions. Therefore, health authorities could identify contacts through epidemiological investigations and conduct proactive testing to prevent further spread. However, recently, many people move between the metropolitan area and other regions, and simultaneous infections are occurring in various daily life settings such as kids' cafes, dance studios, churches, training facilities, military units, and gatherings of acquaintances, making response more difficult.

The increase in '3Cs' (Closed spaces, Crowded places, Close-contact settings) is also a risk factor. As temperatures drop entering winter, indoor activities increase, and with the elevation to Level 2 social distancing reducing outdoor activities, an environment vulnerable to spread has been created. The seasonal characteristic of winter inherently increases the risk of virus spread. A Central Disaster and Safety Countermeasure Headquarters official explained, "In winter, as the air becomes dry and the temperature difference between day and night grows, the human body cannot maintain adequate resistance, and the mucous membranes, which are the first point of contact with the virus, dry out, making it easier for pathogens to invade."

Additionally, with the elevation of social distancing, telecommuting and remote classes have increased, leading to more time spent at home with family and acquaintances, which contributes to the spread. At home after returning, people tend to neglect personal preventive measures, such as not wearing masks while talking with family members or sharing food from the same plate. In fact, cluster infections related to family and acquaintance gatherings, which were only three cases in the last week of last month, increased sixfold to 18 cases in the second week of this month.

Silent transmission by hidden infections among 20s and 30s
Concerns over further spread during year-end parties and Christmas

The spread centered on the younger generation is also problematic. According to health authorities, among the confirmed cases on the day with the highest number since the start of the third wave, those in their 20s and 30s accounted for 35.68%. During the peak of the second wave on August 27, the proportion of people in their 20s and 30s was only 23.13%, about two-thirds of the recent figure. The young generation is socially active, moves frequently, and has many asymptomatic infections, enabling 'silent transmission.'

Deputy Director Kwon Jun-wook of the Central Disease Control Headquarters emphasized, "As seen in recent trends of COVID-19 cases in university areas, young people who have wide activity ranges and many asymptomatic infections need to be more vigilant about COVID-19 and strengthen social distancing."

Especially problematic is the increase in year-end gatherings such as year-end parties and Christmas. Compared to the past, awareness has declined, and fatigue from social distancing adjustments has accumulated, raising concerns about further spread despite strengthened preventive measures such as the suspension of restaurant operations after 9 p.m. Deputy Director Kwon repeatedly urged, "Please refrain from year-end and New Year gatherings with the mindset that there will be no more meetings this year."
