Abstract Seroprevalence studies on SARS-CoV-2 are essential for estimating actual prevalence rates of infection and vaccination in communities. This study evaluated based total anti-nucleocapsid immunoglobulin (N) and/or history. We determined the seroprevalence anti-receptor binding domain (RBD) antibodies across age groups. A cross-sectional was conducted Chonburi province, Thailand, between October 2022 January 2023. Participants included newborns to adults aged up 80 years. All serum samples were tested anti-N Ig anti-RBD IgG. The interviewer-administered questionnaires queried information history records. Of 1459 participants enrolled from population, ~ 72.4% infected. number infections higher children < 5 years, with evidence decreasing significantly increasing age. There no significant differences sex or occupation. Overall, 97.4% had an immune response against SARS-CoV-2. IgG rate lower younger vaccinated individuals slightly increased 100% seropositivity at ages > 60 Our findings will help predict exact Thai population. Furthermore, this is public health decision-making development strategies.

Owing to both vaccine- and infection-induced immunity, the COVID-19 seroprevalence is ~90% in most countries. It important examine protective role of booster vaccines hybrid immunity COVID-endemic state. Utilizing a hospital information system for COVID-19, we conducted cohort study by linking laboratory-confirmed case data national immunization records during BA.5 omicron predominant period (1 August−31 December 2022) Chiang Mai, Thailand. Out 63,009 adults with included study, there were 125 (0.2%) severe COVID outcomes 6.4% had previous infection. Protection against was highest among those at least one vaccine (63%; aHR 0.37 [95%CI 0.19–0.73]) as compared without prior vaccination or natural Hybrid offered better protection (35%; 0.65 0.09–4.73) than primary series alone infection alone. Evaluating risk age group, aged 70 years more nearly 40 times (aHR 39.58 18.92–82.79]) severe-COVID-19 18–39-year group. While remain effective way protecting particularly elderly, may offer additional benefit.

SARS‐CoV‐2 causes the coronavirus disease 2019 (COVID‐19) pandemic. Cross‐species transmission of from humans to domestic animals has been reported. In this study, we conducted a serological survey and molecular investigation infection in dogs cats Bangkok vicinities January 2021 August 2022. A total 2,664 serum samples were examined for antibodies against using nucleocapsid protein‐based ELISA (NP‐ELISA). Our result showed 2.28% (33/1,446) seropositivity 1.81% (22/1,218) cats. The positive NP‐ELISA confirmed surrogate virus neutralization test (sVNT). Of 55 seropositive by NP‐ELISA, two 19 sVNT. supported evidence exposure We also investigated real‐time RT–PCR 156 COVID‐19‐positive households. active dog living with COVID‐19 owner. Genetic phylogenetic analysis its owner variant Omicron BA.2. It is first report pet household Thailand.
