BACKGROUND
We analysed the laboratory surveillance data generated by the network of virology laboratories from January 2016 to July 2018 to describe the epidemiology of chikungunya in India.
METHODS
Suspected patients reporting to virology laboratories are investigated for the presence of immunoglobulin M (IgM) antibodies against chikungunya virus (CHIKV) as evidence of recent infection. We analysed the data to describe the distribution of seropositive individuals by time, place and demographic characteristics.
RESULTS
Of the 49 380 sera tested from suspected patients, 20.5% were seropositive. CHIKV IgM positivity was seen throughout the year, with a peak between September and December. The laboratories diagnosed 28 outbreaks of chikungunya during the study period.
CONCLUSIONS
Laboratory surveillance data indicate continued transmission of CHIKV in many regions of India.
背景
我们分析了 2016 年 1 月至 2018 年 7 月间病毒学实验室网络产生的实验室监测数据，以描述印度基孔肯雅热的流行病学情况。
方法
对向病毒学实验室报告的疑似患者进行检测，以发现针对基孔肯雅病毒（CHIKV）的免疫球蛋白 M（IgM）抗体，作为近期感染的证据。我们分析了数据，以描述按时间、地点和人口统计学特征分布的血清阳性个体情况。
结果
在对疑似患者的 49380 份血清进行检测中，20.5%呈血清阳性。全年均可见 CHIKV IgM 阳性，9 月至 12 月期间达到高峰。实验室在研究期间共诊断出 28 起基孔肯雅热暴发。
结论
实验室监测数据表明，印度许多地区仍在持续传播 CHIKV。
