Abstract
OBJECTIVES
This study examined how trends in the weekly frequencies of gastrointestinal infectious diseases changed before and during the coronavirus disease 2019 (COVID-19) pandemic in Korea, and compared them with the trends in the United States.
METHODS
We compared the weekly frequencies of gastrointestinal infectious diseases (16 bacterial and 6 viral diseases) in Korea during weeks 5-52 before and after COVID-19. In addition, the weekly frequencies of 5 gastrointestinal infectious diseases in the United States (data from the Centers for Disease Control and Prevention) that overlapped with those in Korea were compared.
RESULTS
The mean weekly number of total cases of gastrointestinal infectious diseases in Korea showed a significant decrease (from 522 before COVID-19 to 245 after COVID-19, p<0.01). Only bacterial gastrointestinal infectious diseases caused by Campylobacter increased significantly; other bacterial gastrointestinal infectious diseases showed either a decrease or no change. The incidence of all other viral diseases decreased. In the United States, the weekly numbers of Salmonella, Campylobacter, typhoid, shigellosis, and hepatitis A virus cases sharply decreased after the COVID-19 outbreak. The weekly case numbers of all viral diseases markedly decreased in both countries; however, bacterial gastrointestinal infectious diseases showed a different pattern.
CONCLUSIONS
The incidence of gastrointestinal infectious diseases decreased after the COVID-19 outbreak. In contrast, Campylobacter infections showed an increasing trend in Korea, but a decreasing trend in the United States. Further studies are needed to elucidate the different trends in bacterial and viral infectious diseases before and after non-pharmaceutical interventions and between different countries.
Summary
Korean summary
한국과 미국 모두 코로나-19 발생 이후 위장관 감염 질환의 발생은 감소하고 있습니다. 하지만, 미국과 달리 한국에서는 캄필로박터 감염은 증가 하고 있습니다. 이는 COVID-19이 발생한 이후 캄필로박터 감염의 열악한 통제의 가능성을 설명할 수 있습니다.
Key Message
The incidence of gastrointestinal infectious diseases decreased after the COVID-19 outbreak, however, campylobacter infections showed an increasing trend in Korea, unlike the United States, which could explain the poor control of Campylobacter.
