Japanese Encephalitis News and Research

RSS

Japanese encephalitis (previously known as Japanese B encephalitis to distinguish it from von Economo's A encephalitis) is a disease caused by the mosquito-borne Japanese encephalitis virus. The Japanese encephalitis virus is a virus from the family Flaviviridae. Domestic pigs and wild birds are reservoirs of the virus; transmission to humans may cause severe symptoms. One of the most important vectors of this disease is the mosquito ''Culex tritaeniorhynchus''. This disease is most prevalent in Southeast Asia and the Far East.

Experimental vaccine protects against Zika virus through T cells alone

Zika virus has been spreading for decades, but it first grabbed worldwide headlines in 2016. That February, with an outbreak sweeping the Americas, the World Health Organization (WHO) declared the surge in Zika-linked birth defects a "public health emergency of international concern"-a designation which lasted until that November.

Mitochondrial rewiring may explain why orthoflaviviruses harm humans but persist in mosquitoes

Orthoflaviviruses reshape mitochondrial structure, metabolism, redox signaling, and quality control differently across human and mosquito models, helping explain their contrasting infection outcomes. The review highlights mitochondrial pathways that may support acute cellular damage in vertebrates but persistent, non-lethal infection in mosquitoes, pointing to potential antiviral targets.
