Wind Speed Influences Temperature-Humidity Link to Hand Foot Mouth Disease in Western China

Background: Hand, Foot, and Mouth Disease (HFMD) is a significant public health concern, particularly in pediatric populations. Understanding the climatic factors influencing disease incidence is crucial for effective prevention strategies.

Method: This observational study analyzed meteorological data over a 5-year period in Western China, correlating wind speed with temperature and humidity levels and their joint impact on HFMD cases. Data from public health records and local climate stations were utilized to establish correlations.

Results: Increased wind speed was associated with a 30% reduction in HFMD incidence on days with high temperature and humidity compared to calm days (P<0.01). Specifically, instances of HFMD dropped from an average of 20 cases per week during low wind conditions to 14 cases during windy days.

Conclusion: Findings suggest that wind speed plays a significant role in modulating the temperature-humidity link to HFMD, indicating potential for integrating weather forecasts into public health strategies for HFMD prevention. However, the study's observational nature limits causal inferences, highlighting a need for further investigation.
