Short‐Term Effects of Temperature and Relative Humidity on Hand, Foot, and Mouth Disease in Guiyang, China, From 2022 to 2024: Distributed Lag Nonlinear Model–Based Analysis

Abstract

Meteorological factors, including temperature and relative humidity, have been associated with the incidence of hand, foot, and mouth disease (HFMD). However, these associations vary across regions. Guiyang, a city characterized by a subtropical plateau humid climate, remains understudied with respect to the short‐term associations of temperature and relative humidity with HFMD incidence. This study aimed to quantify the short‐term associations of these meteorological factors with HFMD risk in this understudied setting.
