Abstract Objective To analyze the effect of external temperature and relative humidity on the incidence of hand, foot and mouth disease (HFMD).Methods Information of HFMD patients and weather data during 2011—2014 was collected. The relative risk due to daily mean temperature and daily relative humidity were analyzed using distributed lag non-linear models.Results Temperature of 18 ℃ to 25 ℃, or lower than 5 ℃ and relative humidity lower than 68% could increase the number of HFMD patients. While relative humidity of 85%-100% could decrease the number of HFMD patients in lag 1-2 days.Conclusion In certain range and lag days, external temperature and relative humidity could affect the incidence of HFMD.
