目的分析甘肃省河西走廊地区2006-2010年夏秋季节脑炎脑膜炎症候群病例流行病学及临床特征,为河西走廊地区乙脑监测及防控策略提供理论依据。方法回顾性调查分析河西5市选取的8个市、区(县)辖区内县级及以上医院574例脑炎脑膜炎症候群病例。结果 574例脑炎脑膜炎症候群病例中以病毒性脑炎病例为主,占75.09%,15岁以下儿童发病最为常见,占44.60%,多见于学生、农民、幼托及散居儿童。脑炎脑膜炎症候群病例多急性起病,以轻型、中型为主;主要临床表现依次为头痛、恶心、精神萎靡、发热、呕吐及头晕,结核性脑膜炎患者头痛的发生率明显高于病毒性脑炎及化脓性脑炎患者,差异有统计学意义(P<0.05);化脓性脑膜炎患者精神神经症状的发生率明显高于病毒性脑炎及结核性脑膜炎,差异有统计学意义(P<0.05)。结论病毒性脑炎是河西走廊地区脑炎脑膜炎症候群的主要病种,结合历史数据,仍不能排除河西走廊地区存在乙脑病例的可能性。
Objective To analyze the epidemiological and clinical features of encephalitis meningitis syndrome in the Hexi Corridor region of Gansu Province during the summer and autumn of 2006-2010, and provide a theoretical basis for the monitoring and control strategies of Japanese encephalitis in the Hexi Corridor region. Methods Retrospective investigation was made on 574 cases of encephalitis meningitis in county-level and above hospitals in 8 cities, districts and counties selected by Hexi 5 municipalities. Results Among the 574 encephalitis meningitis syndromes, viral encephalitis cases were the most common, accounting for 75.09%. The incidence of children under 15 years old was the most common, accounting for 44.60%. It was more common among students, farmers, kindergarten and diaspora. Encephalitis meningitis syndrome more acute onset, with light and medium-based; main clinical manifestations were headache, nausea, apathetic, fever, vomiting and dizziness, the incidence of tuberculosis meningitis was significantly higher than the incidence of headache Encephalitis and purulent encephalitis, the difference was statistically significant (P <0.05); the incidence of neuropsychiatric symptoms in patients with purulent meningitis was significantly higher than viral encephalitis and tuberculous meningitis, the difference was statistically significant ( P <0.05). Conclusions Viral encephalitis is a major encephalitis meningitis syndrome in the Hexi Corridor. Combined with historical data, it is still not possible to rule out the possibility of JE cases in the Hexi Corridor.
