Bioaerosols, a significant yet underexplored component of atmospheric particulate matter, pose substantial public health risks, particularly in regions with poor air quality. This study investigates the composition of bioaerosols in public spaces, specifically two interstate motor parks and two marketplaces in Osun State, Nigeria, over six months. Air samples were collected, and bacterial and fungal species were identified, focusing on pathogenic organisms.

Background: Ambient air pollution is a known risk factor for several chronic health conditions, including pulmonary dysfunction. In recent years, studies have shown a positive association between exposure to air pollutants and the incidence, morbidity, and mortality of a COVID-19 infection, however the time period for which air pollution exposure is most relevant for the COVID-19 outcome is still not defined. The aim of this study was to analyze the difference in association when varying the time period of air pollution exposure considered on COVID-19 infection within the same cohort during the first wave of the pandemic in 2020.

Objectives: To explore the epidemiological characteristics of respiratory syncytial virus (RSV) infection in children in Nanchang and its correlation with climate environmental factors.
Methods: The clinical data were collected from children with acute respiratory infection in Nanchang who were tested for RSV at Jiangxi Provincial Children's Hospital from January 2019 to December 2023, along with climate environmental data for the same period. The epidemiological characteristics of RSV and their correlation with climate environmental factors were investigated.
