摘要

以全国31个省、自治区和直辖市的手足口病为研究对象,估算各地手足口病传染率及其季节性,分析可能对季节性有影响的因素。采用时间序列SIR(Time Series Susceptible Infected Recovered (TSIR))模型,并应用马尔科夫蒙特卡洛方法 (Markov chain Monte Carlo,MCMC)估算模型中参数,分析各地月手足口病传染率及季节性,最后建立线性回归模型分析气候、假期和春运对手足口病传染率季节性的影响。结果表明中国各省手足口病传染率都有明显的季节性,根据传染率峰值发生时间,可以将各省归类到4个区域:东南地区峰值在2月~3月,各省传染率季节性多与春运有关;西北地区峰值在4月,传染率季节性主要受相对湿度和春运的影响;北方地区峰值在5月,季节性则受平均气温、暑假和春运的影响;西藏自治区峰值则在8月,其传染率季节性不受上述因素的影响。

Abstract

Based on the HFMD reported cases in 31 provinces, autonomous regions and municipalities of China, this paper estimated the transmission rate of HFMD and its seasonality, then analyzed possible related factors. The Time Series Susceptible Infected Recovered (TSIR) model was established to examine the HFMD transmission rate, and the parameters in the TSIR model were estimated by Markov chain Monte Carlo (MCMC). We also established a linear regression model to analyze the effects of climate factors, school terms and the spring festival travel rush on the transmission rate of HFMD. The results show that the HFMD transmission rate in all provinces of China has obvious seasonality. According to the peak time of HFMD transmission rate, the provinces can be divided into four regions: the peak period of HFMD transmission rate in the southeast region is from February to March, which is affected by the spring festival travel rush; the peak time in the northwest region is April and its seasonality is mainly affected by relative humidity and spring Festival travel rush; in the northern region, the peak period happens in May, which is associated with average temperature, summer vacation and spring festival travel rush; the peak of Tibet Autonomous Region is in August. The seasonality of its isn’t affected by climate or the contact rate.

Key words： hand, foot and mouth disease; transmission rate seasonality; climate factors; school terms; spring festival travel rush
