[현장생중계]Korea Centers for Disease Control and Prevention briefing (March 8) | YTN

[정은경 / 질병관리청장]

We will explain the current status of COVID-19 outbreaks and vaccinations in Korea. As of 00:00 on March 8, there were 335 new confirmed cases in Korea, and 11 cases from overseas were confirmed, so the total number of confirmed cases is 92,817.

Currently, 7701 people are in quarantine, 128 people with serious illness and 8 people died yesterday, so the cumulative death toll is 1642. I wish the deceased people’s blessings and wishes to the bereaved family with a word of deep consolation.

For each case yesterday, I will replace the briefing material and explain the quarantine management situation over the past week. The number of confirmed cases in Korea averaged 371.7 per day for the last week, an increase of 2.3 and 0.6% from the previous week.

The number of confirmed overseas inflows is on average 19.4 for the last week, and the number of confirmed overseas inflows is decreasing from the average of 30 to less than 20 in the 2nd week of February.

When looking at the occurrence status of each region, the metropolitan area, Chungcheong, Gyeongnam, and Jeju areas increased compared to last week, and Honam, Gyeongbuk, and Gangwon areas showed a decreasing trend compared to Jeonju.

Looking at the route of infection, 34.5% of cases were contacted with prior confirmed patients, 31.7% of group outbreaks, and 5% of cases from overseas. The rate of incidence in hospitals and nursing facilities has decreased significantly from 13% in the third week of February to 4.5% in the last week. Currently, 662 cases are being investigated, accounting for 24.2% of the total.

A total of 21 cases of new outbreaks were reported in the past week. The most common cases were family and acquaintance meetings, 7 workplaces, especially manufacturing centered workplaces, 3 multi-use facilities, and other group outbreaks of foreign workers in Dongducheon and military bases in Sejong City. .

The number of people with severe gastric disorders and deaths continues to decline. The fatality rate also declined slightly over the past week to 1.77%. However, the fatality rate among the elderly in their 80s and above is still high at 20.7%. There were a total of 37 deaths in the past week.

Most of them were in their 80s, and those in their 80s and older accounted for the most at 48%. The main presumed path of infection of the deceased was death in such facilities and hospitals, such as nursing hospitals and nursing facilities, with 43% being the largest, most of them with underlying diseases.

Next, I will tell you about the status of the mutant virus confirmation. A total of 248 cases have been analyzed since last week on March 4. Of the 222 cases that occurred in Korea, 213 cases were not identified, and 9 cases were identified.

In the case of foreign inflow, a total of 26 tests were conducted, of which 15 cases were not detected, and 11 cases were confirmed.

Among them, there were 16 mutant viruses in the UK, 3 mutant viruses in South Africa, and 1 mutant related to Brazil. Accordingly, a total of 182 mutant viruses have been identified since October, and the UK mutant virus was the highest with 154 cases.

Of the 20 mutant virus infections identified last week, 11 were foreign cases and the remaining 9 were domestically infected. Of the cases of overseas inflow, 2 were confirmed in the quarantine stage, and the remaining 9 were confirmed by inspections conducted during self-isolation after entering the country.

Nine domestic infections were all Koreans and were confirmed related to five group cases. As a result of the mutant virus test conducted in the process of strengthening community surveillance, 6 cases in the UK and 3 cases in South Africa were confirmed.

The quarantine authorities continue to expand the monitoring and analysis of mutant viruses, such as strengthening quarantine for foreign residents, and in particular, we reiterate that those who are subject to self-isolation and their family members who have entered overseas must strictly follow the rules of self-isolation until the time the quarantine is released. .

Influenza outbreaks last week continued to remain below the epidemic standard. The number of confirmed cases in Korea turned to a decline last week, but the situation is still stagnant.

In particular, as the outbreak of groups such as workplaces and multi-use facilities is on the rise, I will tell you about the risk factors and requirements for the spread of infection. The first risk factor is the increasing number of groups in small and medium-sized manufacturing workplaces and multi-use facilities.

Recently, group infection of small and medium-sized manufacturing industries in the center of Gyeonggi and Chungcheong area continues.In particular, the risk of infection is high due to the 3-mil working environment, dormitory, and co-living, but it is difficult to detect early due to limited medical access, This is a situation with low accessibility.

In addition, group infections in indoor sports facilities, dance halls, restaurants and pubs, saunas, churches, daycare centers, and private academies have been reported continuously.

The quarantine authorities are reinforcing the inspection of workplaces vulnerable to infections such as collective residence of foreign workers in epidemic areas such as the metropolitan area and Chungcheong area in connection with the special inspection of the Ministry of Employment.

Second, there is an increasing risk of increased human contact due to school attendance in March, spring trips, and meetings. Accordingly, we will strengthen on-site inspections for the implementation of quarantine rules for entertainment facilities and multi-use facilities, and reinforce measures for violating companies.

In addition, by selecting high-risk areas and high-risk occupations by local governments, we will continue to strengthen local community quarantine such as inspections. The third is the risk of community spread from mutant viruses.

As reported today, mutations were also found in cases of infection in the community. The quarantine authorities are obligated to submit a negative confirmation letter, including both foreign and domestic residents, and will do their best to block the influx of mutant viruses, such as thorough inspection and self-quarantine before quarantine for foreign visitors once entering the country.

In recent years, the proportion of the entire infection path, including family members, acquaintance groups, and multi-use facilities, is increasing. We ask that you observe the quarantine rules and distance distancing as the risk of spreading increases when movements between regions due to travel, outings, etc. increase or contact between people increases.

First, always wear a mask indoors, regardless of location or situation. Second, please practice distancing, such as prohibiting gatherings of more than 5 people.

Third, if you have any suspicious symptoms such as fever or respiratory symptoms, we ask you to undergo an examination immediately. Next, we will report on the status of vaccinations.

As of March 8, the first dose of the Corona 19 vaccine has been completed for 316,865 people so far. The vaccination rate so far is 41.5%, and out of the 760,000 planned for February and March, the vaccination was completed for 316,000, 41.5%.

By vaccination institution and target, 81.3% of nursing hospitals, 49.9% of nursing facilities, and 1st response personnel are currently in progress, and 27.7% of hospital-level medical institutions also received vaccinations.

Next, we will talk about adverse reactions after the COVID-19 vaccination. Yesterday, an additional 266 cases were reported, and a total of 3915 cases have been vaccinated and reported adverse reactions to date.

Among them, 3866 cases were mild cases such as headache, fever, nausea, and vomiting, which can be common after vaccination, and 33 cases of anaphylaxis and 5 serious suspected cases including convulsions were reported, and 11 cases of death have been reported so far. In the middle.

We will explain the results of the weekly analysis of suspicious cases of adverse reactions reported from February 26 to March 6 last week. To date, 1.2% of all vaccinators reported suspicious cases of adverse reactions.

By gender, 1.3% of women reported more than 0.8% of men, and by age, 3% were reported in their 20s, 1.7% were in their 30s, and 0.4% were in their 60s.

When looking at the status of notifications by vaccination target, the reporting rate was 1.2% for institutional workers and 0.4% for patients hospitalized or admitted to the institution.

By type of institution, hospital-level medical institutions reported the highest report rate at 1.7%, followed by nursing hospitals at 0.9%, nursing facilities at 0.9%, and Corona 19 treatment hospitals at 0.3%.

By vaccine manufacturer, 1.2% of those who received the AstraZeneca vaccine and 0.3% of those who received Pfizer reported adverse reactions. By clinical symptoms of the reported adverse reactions, muscle pain was the most, 65%, followed by fever, 58.2%, headache, and chills. Most of the symptoms that could occur during the natural immunity formation process were 98.7%.

The results of the vaccination damage investigation group’s meeting will be explained separately by the head of the damage investigation group. Lastly, I would like to ask you again about the precautions for vaccination.

Before receiving the vaccination, be sure to receive the vaccination in a healthy state, and when you receive a doctor’s examination, be sure to record your allergy history and other precautionary information in detail.

You should not be vaccinated if you have had a severe allergic reaction such as anaphylaxis to the components of the COVID-19 vaccine. In addition, if you have suspected infection, fever or acute illness, you should postpone vaccination.

After vaccination, all vaccination completed persons need to stay at the vaccination facility for 15 to 30 minutes after vaccination and check whether adverse reactions such as anaphylaxis have occurred. Please observe your physical condition with interest.

After vaccination, local reactions such as pain, swelling, and redness may occur at the vaccination site, and systemic reactions such as fever, fatigue, headache, muscle pain, nausea, and vomiting may occur. As such, the most common adverse reactions after vaccination are said to disappear within 2 to 3 days.

If there is pain or swelling at the vaccination site, it may be helpful to put a cold towel on the vaccination site or take pain relievers if there is an adverse reaction to the systemic site.

However, if you have symptoms that show severe allergic reactions or have symptoms that exceed general adverse reactions such as persistent high fever, we ask you to seek medical care and visit a medical institution to receive medical treatment.

Next, the head of the vaccination damage investigation team will explain the results of the damage investigation.

[김중곤 / 예방접종피해조사반장]

First, I will briefly introduce the composition of the vaccination damage investigation group. The vaccination damage investigation group was originally composed of 10 or less members. It currently consists of eight people.

It is organized based on each medical professional. So, a professor who majors in infectious science, respiratory allergy, neurology, forensics major, and immunology major. This is the current configuration.

And the role of the vaccination damage investigation team is to first verify the presence or absence of the vaccine if there is a serious abnormal case that occurs after vaccination, and also to confirm the causal relationship between the severe adverse reaction and the vaccine. Do it.

Based on this work, it can be said that the role of the damage investigation team is to decide whether to continue or not to continue the vaccination project.

As mentioned above, I briefly talked about the operation and composition of the damage investigation team, and from now on, I will tell you about the results of the meeting that took place yesterday. Yesterday, we investigated the causal relationship between vaccinations for 8 minutes reported as dead after the COVID-19 vaccination.

When doing research, the principles were divided into three. The first was about the presence or absence of the vaccine itself, and the second was to review the occurrence of anaphylaxis in the case of severe adverse reactions caused by the vaccine, especially in the case of the Corona 19 vaccine.

Third, we reviewed the presence or absence of an underlying disease that the deceased had. First of all, eight minutes were examined for the vaccine itself.

First of all, we checked whether there were any serious adverse reactions to vaccinations that occurred to those who took the same vaccination on the same day and at the same place.

However, since there were no accompanying cases in such a case, it was judged that there was no problem with the vaccination itself, the vaccine itself, or in the vaccination process.

Next, based on the collected data, we reviewed cases of death. Eight deaths were investigated to see if there were any cases of anaphylaxis, a disease that could cause rapid death after vaccination.

Fortunately, it was confirmed that there were no such symptoms corresponding to anaphylaxis. In addition, according to the investigation of the underlying disease, most of the patients have cerebrovascular disease or cardiovascular disease as an underlying disease, so it was judged as death due to aggravation of the underlying disease.

Also, at the time of death, we also reviewed whether there were any symptoms that were suspected to be adverse reactions after vaccination, but it was judged that there were no signs of any special adverse reactions.

Therefore, in conclusion, it was tentatively decided that the relationship between adverse reactions and death after vaccination in 8 cases of death reported after vaccination with COVID-19 was difficult to be recognized.

However, four of the survey subjects are currently undergoing autopsies at the National Institute of Scientific Investigation, so the final autopsy results will be confirmed and the Vaccination Damage Research Team will conduct additional evaluations.

This is the result of yesterday’s meeting.

[사회자]

Then, we will first ask you the preliminary question sent by the reporters related to the adverse reaction report case. In order, I will ask the third question first.

It is related to the underlying disease and also to the death case. I would like to ask a question to Professor Yong-gyun Cho. There was no underlying liver-related disease, but there was a case of death from acute cirrhosis after vaccination.

Could you please explain whether it was attributed to the COVID-19 vaccine or whether there were other factors, and how far the epidemiological investigation has progressed?

[조용균 / 가천의대 감염내과 교수]

I will tell you. I reviewed 8 patients yesterday and I think it is the 7th case. In the case of this patient, in the past in the nursing hospital, he was in a state of illness due to cerebral hemorrhage, and it was such a patient who was unable to express his or her intention smoothly.

Vaccine-induced death in the form of fulminant hepatitis has not been reported in the world so far, and it has been judged that the likelihood of this patient is unlikely.

Then why did this patient suddenly die with hepatitis? As a result of yesterday’s review, this patient is probably the most presumably such patient who died of acute sepsis due to cholangitis while the patient’s illness was not identified at an early stage due to poor self-expression.

So this patient judged that there was little likelihood of association.
