Orang Primary Health Centre (OPHC) and Balipara Primary Health Centre (BPHC) of Assam (India) report mosquito borne diseases annually. Current study was performed to ascertain the prevalence of known malaria and Japanese Encephalitis (JE) vectors and their possible role in disease transmission.
Malaria epidemiological data for 2006-2010 and JE data for 2008-2013 of Assam, India were obtained from the health authority. Mosquitoes were collected using CDC light traps and identified morpho-taxonomically.
cases (81.5%, 95% CI= 72.0-91.1) were statistically higher in OPHC (P< 0.0001, t= 8.0) during the recent years. There was 4.4 folds rise in the confirmed acute encephalitis syndrome (AES) and 3.2 folds increase in the confirmed JE cases during 2013 as compared to 2008. Altogether 9,218 mosquito specimens (PTND= 153.6), comprising of 44.1% anophelines (PTND= 67.7), 42.3% culicines (PTND= 65.0) and 9.5% mansonia (PTND= 14.6) were recorded. In BPHC, was recorded in high density (P< 0.0001), whereas was the predominant JE vector (P= 0.04). In OPHC, among the known malaria vectors, the density of was significantly high (P< 0.0001). However was the predominant known JE vector (P< 0.0001) followed by
Even in the absence of known efficient vectors, many species are still involved in malaria transmission. There was disappearance of and and establishment of , and mosquitoes in study area.
印度阿萨姆邦的奥兰格初级卫生中心(OPHC)和巴利帕拉初级卫生中心(BPHC)每年都会报告蚊媒疾病。开展本研究以确定已知疟疾和日本脑炎(JE)病媒的流行情况及其在疾病传播中的可能作用。
从卫生当局获取印度阿萨姆邦2006 - 2010年的疟疾流行病学数据以及2008 - 2013年的日本脑炎数据。使用疾控中心诱蚊灯收集蚊子,并进行形态分类鉴定。
近年来,OPHC的病例数(81.5%,95%置信区间 = 72.0 - 91.1)在统计学上更高(P < 0.0001,t = 8.0)。与2008年相比,2013年确诊的急性脑炎综合征(AES)增加了4.4倍,确诊的日本脑炎病例增加了3.2倍。共记录了9218只蚊子标本(每诱捕点捕获蚊数 = 153.6),其中按蚊占44.1%(每诱捕点捕获蚊数 = 67.7),库蚊占42.3%(每诱捕点捕获蚊数 = 65.0),曼蚊占9.5%(每诱捕点捕获蚊数 = 14.6)。在BPHC,[此处原文缺失具体蚊子种类信息]的密度很高(P < 0.0001),而[此处原文缺失具体蚊子种类信息]是主要的日本脑炎病媒(P = 0.04)。在OPHC,在已知的疟疾病媒中,[此处原文缺失具体蚊子种类信息]的密度显著较高(P < 0.0001)。然而,[此处原文缺失具体蚊子种类信息]是主要的已知日本脑炎病媒(P < 0.0001),其次是[此处原文缺失具体蚊子种类信息]
即使在没有已知有效病媒的情况下,许多[此处原文缺失具体蚊子种类信息]物种仍参与疟疾传播。研究区域出现了[此处原文缺失具体蚊子种类信息]和[此处原文缺失具体蚊子种类信息]的消失以及[此处原文缺失具体蚊子种类信息]、[此处原文缺失具体蚊子种类信息]和[此处原文缺失具体蚊子种类信息]蚊子的定殖。
