Hand-foot-and-mouth disease is an infectious disease that is very common in children. Most of the symptoms are mild. Germs that cause hand-foot-and-mouth disease die easily in dry places and heat. Therefore, it is related to meteorological factors. This study aimed to study the relationship between the number of HFMD patients and meteorological factors in Khon Kaen Province. The secondary data of monthly, statistics including the number of patients with HFMD and meteorological factors of Khon Kaen Province between 2020 and 2024, were collected from the Bureau of Epidemiology, Ministry of Public Health, and the Upper Northeastern Meteorological Center, respectively. Data was analyzed using descriptive statistics, Pearson’s correlation coefficient, and the generalized linear regression models.
The results showed that there is a moderate correlation between the average amount of rainfall and the monthly average number of HFMD patients, the Pearson correlation coefficient was 0.439 (p-value <.05). The generalized Poisson regression model and the negative binomial regression model that best fit the data included only average monthly rainfall as the only explanatory variable, the coefficient of determination (R²) is equal to 0.363 and 0.293, respectively. The generalized Poisson regression equation: y=exp (4.531+0.185x), where y is the number of HFMD patients, can be explained by x as the average rainfall. When exp (0.185) is equal to 1.20, then the number of HFMD patients will increase from the average by 20 percent when the average rainfall increases by 1 millimeter.
