Article Abstract
This study investigated the relationship between air pollution and influenza incidence in Chongqing from 2013 to 2022 using a generalized additive model (GAM), analyzing 199,712 cases. Subgroup analyses were conducted to investigate the impact of age, gender, season, and the COVID-19. Influenza incidence was positively associated with PM, PM, SO, NO and CO, but negatively with O. SO had the most effect. In single-day lag models, the largest percentage changes in influenza incidence at lag0 for each pollutant were: 2.930% for SO, 1.552% for CO, -0.637% for O, 0.516% for PM, and 0.405% for PM. NO showed the largest change at lag11 (1.376%). In multi-day lag models, changes peaked at lag011-014. Stratified analyses revealed children aged 0-14 years as particularly vulnerable during the cold season and COVID-19 period. The study demonstrates that short-term lags and cumulative effects of air pollution exposure increase influenza incidence, significant for establishing influenza response strategies.

Evaluation of Kindergarten Through Grade 12 All-Cause Absenteeism Data as an Indicator and Predictor of Respiratory Disease, 2018-2022.

Objectives: Increases in absenteeism among schoolchildren may precede increases in incidence of community-level respiratory diseases. This study assessed the correlations and predictive values between all-cause absenteeism among kindergarten through grade 12 students and community-level increases in influenza and COVID-19.
Methods: We used absenteeism data from 4 school districts (1 each in Arizona, California, Nevada, and Wisconsin) between fall 2018 (starting approximately late August) and spring 2022 (typically ending in May) to calculate correlations between school absenteeism and community-level cases of influenza, percentage of influenza-like illness, and COVID-19.
Monitoring of Influenza and Influenza-Like Viruses in the 2022/2023 and 2023/2024 Epidemic Seasons Using the SENTINEL and NON-SENTINEL Surveillance Systems in Poland.

BACKGROUND The SENTINEL influenza surveillance system has been used in Poland since 2004, incorporating both epidemiological and virological monitoring of influenza viruses. SENTINEL works in cooperation with general practitioners, 16 Voivodship Sanitary Epidemiological Stations (VSES), and the National Influenza Centre (NIC). NON-SENTINEL samples are collected from places that do not participate in the SENTINEL program.

Introduction: Influenza infection can cause serious complications in the elderly, including hospitalizations and death. In Taiwan, government-funded influenza vaccination is offered to the elderly ≥65 years old. We aim to evaluate vaccine effectiveness (VE) among this group during 2023-2024 influenza season using national databases.

In this context, windborne transmission, the idea that the virus could travel through the air over considerable distances, is a contentious concept, and documented cases have been rare. Here, though, we provide genetic evidence supporting the feasibility of windborne transmission.

Unlabelled: Benign Acute Childhood Myositis (BACM) is a transient, self-limiting muscular condition that typically follows viral infections, especially influenza. The COVID-19 pandemic disrupted the circulation of respiratory viruses, altering the epidemiology of related post-infectious complications. This study investigates trends in BACM incidence, clinical features, and viral etiology before and after the pandemic.
