Studio sero-epidemiologico dell'infezione da virus respiratorio sinciziale in Corea.

BACKGROUND: Despite the recent introduction of a respiratory syncytial virus (RSV) vaccine, there is no sero-epidemiologic study of RSV infection among old adults in Korea. This study aimed to assess humoral immune responses to RSV among different age groups in Korea. METHODS: A total of 400 serum samples (100 samples from each of the following age groups: 10-20, 21-40, 41-60, and 61-80 years) were selected randomly from a general population cohort used for health status evaluation in Korea (the Korea National Health and Nutrition Examination Survey 2019-2020 cohort). Anti-RSV IgM and IgG levels, along with total IgM and IgG levels, were measured in enzyme-linked immunosorbent assays. RESU
