韶关市地处粤北山区,虽然多年对伤寒的防治作了不懈的努力,使该病的发病水平呈现逐年下降的趋势。但由于局部地区偶有暴发,致使全市发病率仍徘徊在6/10万以上。为进一步了解该病暴发的特征及流行因素,我们对1985年以来韶关市4起较重大的伤寒暴发调查资料进行了分析。流行地区与流行强度:4起伤寒暴发、分布于城镇和农村各2起。城镇两起的罹患率分别为381/10万和700/10万;农村两起的罹患率分别为1972/10万和
Shaoguan City is located in northern mountainous areas in Guangdong, although many years of typhoid prevention and treatment made unremitting efforts, so that the incidence of the disease showed a downward trend year by year. However, due to occasional outbreaks in some areas, the city’s incidence still hovering at 6 / 100,000 or more. To further understand the characteristics of the disease outbreak and epidemic factors, we analyzed the investigation data of 4 major typhoid outbreaks in Shaoguan since 1985. Popular areas and epidemic intensity: 4 typhus outbreaks, distributed in urban and rural areas each 2. The prevalence rates of urban areas and urban areas were 381 / 100,000 and 700 / 100,000 respectively; the incidence rates in rural areas were 1972 /
