Abstract
ObjectiveTo evaluate the running status of Qinghai provincial measles laboratory network during 2012—2017.
MethodsTo analyze serological and virological surveillance database developed in Qinghai provincial measles laboratory network in 2012—2017, and evaluate the indicators for the running status of measles laboratory network in Qinghai Province.
ResultsIt was shown that 5 763 suspected measles cases were reported in Qinghai Province during 2012—2017, and 4 167 serum samples were collected from suspected measles cases, the collection rate is 72.31%; among them, 3 697 were IgM positive for measles and the positive rate was 88.72%; 68 were IgM positive for rubella and the positive rate was 1.63%. And 515 throat swab specimens were collected from suspected measles cases, 82 measles virus isolates were obtained and the positive rate was 15.92%. The result of sequencing and analysis showed that all the measles viruses belonged to genotype H1 and subgenotype H1a, which were predominant genotype circulated in China in recent years. In addition, Qinghai provincial measles network labs passed all the serological confirmatory test and proficiency test, and on-site review held by national or provincial measles laboratory and WHO during 2012—2017, respectively.
ConclusionsQinghai provincial measles laboratory network has been established and running well. It provided important scientific basis for measles elimination in Qinghai province.
