1981年～84年我科共收治239名婴幼儿轮状病毒性肠炎。并对其发病与气温、湿度及日照的关系进行了分析。结果:①气温对发病有明显影响。发病主要集中在10～12月,11月为每年的发病高峰(占全年发病总数的58.7～75.3%)。石家庄地区该期的温度为-1.1～11℃,发病人数最多(占93.3%)。该温度为轮状病毒的最适温度。其中以2.1～5℃组发病人数最多,占全部病人的41.8%。各气温组发病人数经统计学处理有非常显著差异(P<0.01)。②湿度与发病无明显关系。③在适宜气温条件下,日照与发病有密切关系。即日照时间长发病人数少。从而进一步推测紫外线对轮状病毒有杀伤作用。此问题尚需进一步探讨。
From 1981 to 1984, our department treated a total of 239 infants with rotavirus enteritis. The incidence and temperature, humidity and sunshine were analyzed. Results: ① temperature had a significant impact on the incidence. The incidence mainly concentrated in 10 to December, the peak incidence in November each year (accounting for the annual total incidence of 58.7 ~ 75.3%). Shijiazhuang, the temperature during the period of -1.1 ~ 11 ℃, the largest number of patients (accounting for 93.3%). The temperature is the optimum temperature for rotavirus. Including 2.1 ~ 5 ℃ group the largest number of patients, accounting for 41.8% of all patients. The number of patients in each temperature group were statistically significant (P <0.01). ② humidity and incidence of no significant relationship. ③ in the appropriate temperature conditions, sunshine and the incidence are closely related. That sunshine time long incidence of small number of patients. It is further speculated that ultraviolet light has a killing effect on rotavirus. This issue still needs to be further explored.
