Abstract
Japanese Encephalitis, Tibet, China
Highlights
Serologic assays detected anti-Japanese encephalitis virus (JEV) antibodies in a large number of human and porcine serum samples collected in this region
To determine whether local residents were infected by JEV, 248 human serum samples were collected in Mainling and Medog Counties from healthy persons
The observation that 68 (27.4%) of 248 serum samples from healthy humans contained neutralizing antibody against JEV at titers >10 suggests that this population is subject to substantial levels of subclinical JEV infection
Summary
4. Zhan L, Cao WC, Jiang JF, Zhang XA, Liu YX, Wu XM, et al Anaplasma phagocytophilum from rodents and sheep, China. JEV was isolated from Culex tritaeniorhynchus mosquitoes, the main vectors of JEV, collected in Tibet. Serologic assays detected anti-JEV antibodies in a large number of human and porcine serum samples collected in this region. The dominant mosquito species detected in Medog County was Cx. tritaeniorhynchus (2,442 [71.1%] of 3,436 mosquitoes collected there) (Table); no previous reports have described this species in Tibet.
