Due to the new coronavirus infection pandemic (Corona 19), the main legal infectious diseases decreased significantly as vital quarantine, such as wearing a mask and washing hands, was strengthened.

The research team of Professor Kang Ji-won of the Department of Pediatric Infectious Immunology at Severance Hospital of Yonsei University (a joint research with Professor of Samsung Seoul Hospital Heo Gyeong-min and the team of Professor Jeong Jae-hoon of Kim Jong-heon and Gil Hospital) relies on social distancing, wearing a mask, etiquette when coughing, and hand hygiene to prevent COVID-19 infection. On the 11th it was announced that the detection rate for respiratory viruses, including legal infectious diseases, has dropped significantly.

So far there have been studies directed at hospital or regional units, or nonspecific clinical diagnoses such as flu symptoms or pneumonia, but this is the first time that the incidence trend has been compared and analyzed with precision at the national level.

The research team confirmed five types of infectious diseases (chickenpox, mumps, invasive pneumococcal infection, scarlet fever, whooping cough) and the pattern of respiratory viral infections under sample control.

From 2016 to February to July 2019, the incidence of chickenpox and mumps, invasive pneumococcal infection, scarlet fever, and whooping cough reported to the Korea Centers for Disease Control and Prevention, and the national COVID-19 incidence from February to July 2020 Compare incidence rates.

As a result of the research, it was found that the five infectious diseases since Corona 19 have decreased significantly compared to the last four years.

In the case of chickenpox, there were 278.01 cases per 1 million people, up 38.4% of the 723.47 cases per year from 2016 to 2019. 54,060 cases of chickenpox were reported in 2016, 892 cases in 2017, 96,467 cases in 2018 and 82,868 cases in 2019. In 2020, in November, the number of cases decreased significantly to 27,542.

The show was 111.01 cases in 2020 per 1 million people, compared to 189.22 cases in 2019 as of 2016, at 58.7%. Invasive pneumococcal infections were 3.20 cases per 1 million people in 2020, 57.6% of the 5.56 cases surveyed between 2016 and 2019.

Scarlet fever also decreased to 25.87 cases in 2020, down 15.8%, compared to 163.57 cases from 2016 to 2019 based on a population of 1 million. Whooping cough was 1.25 cases in 2020, 34.2% compared to 3.66 cases from 2016 to 2019.

The number of positive virus detections, which is the leading cause of respiratory infections, also tended to decline rapidly.

As a result of sampling surveillance, the average number of enterovirus infections from 2016 to 2019 was 1,229.25, but decreased to 39 in 2020. Adenovirus infections also decreased to 914 in 2020 from 4,827.50 from 2016 to 2019. Various respiratory viruses , like Boca, RSV and rhinovirus, they have also declined dramatically.

Professor Kang Ji-won said, “If social distancing, such as wearing a mask and washing hands, is properly maintained, the outbreak of various respiratory infections that have Corona 19-like symptoms can be suppressed.” “We have obtained evidence that it can reduce the costs and respiratory infections that are prevalent in winter.”

The results of this study were published in the latest issue of ‘Clinical Infectious Diseases (IF 8,313)’, a global journal on infectious diseases.
