A decrease in the incidence of encephalitis in South Korea during the COVID‐19 pandemic: A nationwide study between 2010 and 2021
Limited data are available on the impact of the coronavirus disease (COVID‐19) pandemic on encephalitis. Therefore, we evaluated trends in encephalitis in South Korea between 2010 and 2021 using data from the National Health Insurance Service. During the pandemic (February 2020 to 2021), the monthly...

Therefore, we evaluated trends in encephalitis in South Korea between 2010 and 2021 using data from the National Health Insurance Service. During the pandemic (February 2020 to 2021), the monthly incidence of encephalitis declined by 0.027 per 100 000 population (95% confidence interval [CI]: −0.055 to 0.001, p = 0.062) compared to that before the pandemic. In subgroup analysis, the estimated coefficient for level change during the pandemic in the 0–4 and 5–9 years age groups were −2.050 (95% CI: −2.972 to −1.128, p |

The intensive care unit admission rate (39.1% vs. 58.9%, p < 0.001) and cases of death (8.9% vs. 11.1%, p < 0.001) decreased significantly during the pandemic compared to the prepandemic. During the pandemic, the incidence of encephalitis decreased markedly in South Korea, particularly in children aged ≤9 years.
