Abstract

Changsha, a city of 10 million people in China, has complex patterns of influenza activities. There is limited evidence on how temperature influences influenza activity across different populations in a subtropical region. We collected influenza surveillance data from all medical facilities in Changsha City from 2017 to 2023. The effects of temperature on various influenza indicators, including daily frequency of influenza, influenza-like illness (ILI) rate, influenza A (FluA) rate, and influenza B (FluB) rate, were assessed using the distributed lag nonlinear model. This study revealed temperature exhibited the most significant impact on influenza activity. The low temperature (below 10°C) increased the effect on all influenza indicators, while the high temperature (above 25°C) primarily enhanced the effect on FluA and ILI rates. The impact on populations aged 6-17 years was significantly stronger than on other groups. The research results could provide reference for influenza prediction and early warning.

期刊介绍: International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
