Genotype III-Based Japanese Encephalitis Vaccines Exhibit Diminished Neutralizing Response to Re-emerging Genotype V

Published on 02/06/2026 |  Original article (Full-text)  | Ah-Ra Lee et al. | The Journal of infectious diseases 2024; aop: 10.1093/infdis/jiae589 1 min.

Japanese encephalitis (JE) has been predominantly controlled through vaccination. However, the isolation of JE virus (JEV) genotype V (GV) in China in 2009, and the subsequent alarming increase in JE cases in the Republic of Korea since 2010, present a new challenge. Serum samples from individuals vaccinated...

Genetic diversity and Wolbachia infection in the Japanese encephalitis virus vector Culex tritaeniorhynchus in the Republic of Korea

Published on 02/06/2026 |  Original article (Full-text)  | Jeon Jiseung et al. | Parasites & Vectors 2024; 17(1): 518 6 min.

Culex tritaeniorhynchus Giles, 1901 is a mosquito species with a global distribution that includes Africa, Asia, Australia and Europe [1, 2] and is a primary vector of Japanese encephalitis virus (JEV). Enzootic transmission of JEV occurs through amplifying hosts, such as pigs and water birds....

The neurotropic virus Japanese encephalitis virus invades the human central nervous system, inducing neuroinflammation and further disruption of the blood-brain barrier. JEV interacts with various cell types of the blood-brain barrier including the endothelial cells. The present work aims to investigate...

Japanese Encephalitis in Asia: A Comprehensive Review.

Published on 02/06/2026 |  PubMed  | Harshani Hewa Babarandage Chathurika et al. | Journal of vector borne diseases 2025 Apr 2 min.

Japanese encephalitis (JE) which is caused by Japanese encephalitis virus (JEV) is a significant public health concern in Asia. The JEV is mainly transmitted by Culex mosquitoes breeding in flooded rice fields. The disease can range from mild flu-like symptoms to severe encephalitis and long-term neurological...

National burden of and optimal vaccine policy for Japanese encephalitis virus in Bangladesh: a seroprevalence and modelling study

Published on 19/05/2026 |  Original article (Full-text)  | Duque, Mariana Perez et al. | The Lancet Infectious Diseases 2026; 26(4): 429-38 1 min.

Bangladesh first reported Japanese encephalitis virus (JEV) in 1977 and has seen regular cases since; however, no JEV vaccination programme currently exists. A barrier to the use of JEV vaccines has been a limited understanding of the underlying burden. We conducted a nationally representative serological...
