A study result showed that there were more infected people than confirmed people by testing, and the loophole of K quarantine, which relied on diagnostic tests and tracking, showed that the distance was neutralized.
The report by US statisticians did not adequately represent the population because the Centers for Disease Control and Prevention (CDC) quarantine model was based on confirmed cases through testing and relied on state-by-state reporting. The Hill, the US congressional media outlet, reported on the 28th.
The papers published in the Proceedings of the National Academy of Sciences (PNAS), published in the Proceedings of the National Academy of Sciences (PNAS), reported that as of March 7, when the corona spread, the actual number of infected people was estimated by estimating the actual number of infected people, such as the number of confirmed cases and tests, and the number of infected people was about 65 million. The number of confirmed cases on that day was double the CDC's total of 32.67 million.
As a result of the Korea Centers for Disease Control and Prevention's test results, if you rely on the quarantine quarantine according to the confirmed cases, the spread due to the gap with the actual infected person is unlikely to have any effect in the three weeks of raising the distance to the fourth stage.
The results of the US study show that only 1 out of 2.3 infected people were counted as confirmed cases through testing, 1.3 were excluded from the statistics, and the process leading to the subsequent spread of the confirmed cases.
The U.S. study diagnosed that, due to gaps between study estimates and CDC statistics, differences in state reporting procedures and the CDC did not adequately represent the population from the actual site of infection due to test-diagnosed statistics.
A research team at the Chinese Center for Disease Control and Prevention, who studied the delta mutation, announced on the 21st that the incubation period for the mutation was accelerated to 4 days, unlike the one week incubation period before the mutation, and the proliferated virus was excreted 1200 times higher.
K quarantine adheres to the quarantine system for epidemiological investigations and diagnostic tests on mobile phones tailored to the incubation period of one week, and the number of confirmed cases in the metropolitan area is 953 per day after step 4 (18th-22nd), and the previous 11th ~ The daily average on the 15th was 961.8, so the distance head upgrade was neutralized.
From the 22nd to the 28th, the number of confirmed cases per week was 1465, with an average of 1,495 per day.
As a result of the analysis of mobile phone movement volume at the briefing on the 28th, Director Young-rae Sohn showed 226.04 million cases nationwide from the 19th to the 25th, an increase of 0.8% from the previous week, 112.57 million cases in the metropolitan area, an increase of 1.0% from the previous week, and a 0.7% increase in the non-metropolitan area to 100 million Based on the 13.47 million records, he said, "The amount of movement in the metropolitan area last week was 18% higher than in the first week of January," he said.
