Travelers to Asia are at risk for acquiring Japanese Encephalitis (JEV), an arbovirus with high rates of morbidity and mortality. Recent advances in vaccination resulting in vaccines with low rates of side effects have strengthened the rationale to vaccinate more travelers to this region, as reflected in many updated national guidelines for prevention of disease in travelers. Vaccines however s...

The persistent transmission of Japanese encephalitis virus (JEV) in Taiwan necessitates exploring the risk factors of occurrence of Japanese encephalitis (JE). The purpose of this study was to assess the relationship between meteorological factors and the incidence of JE in Taiwan. We collected data for cases of JE reported to the Taiwan Centers for Disease Control (Taiwan CDC) from 2000 to 201...

More than a million Japanese encephalitis (JE) cases occurred in mainland China from the 1960s to 1970s without vaccine interventions. The aim of this study is to analyze the spatial and temporal pattern of JE cases reported in mainland China from 1965 to 1973 in the absence of JE vaccination, and to discuss the impacts of climatic and geographical factors on JE during that period. Thus, the da...

Japanese encephalitis (JE) is arguably one of the most serious viral encephalitis diseases worldwide. China has a long history of high prevalence of Japanese encephalitis, with thousands of cases reported annually and incidence rates often exceeding 15/100,000. In global terms, the scale of outbreaks and high incidence of these pandemics has almost been unique, placing a heavy burden on the Chi...

The emergence of Japanese encephalitis virus (JEV) in the Himalayan highlands is of significant veterinary and public health concern and may be related to climate warming and anthropogenic landscape change, or simply improved surveillance. To investigate this phenomenon, a One Health approach focusing on the phylogeography of JEV, the distribution and abundance of the mosquito vectors, and sero...

Japanese encephalitis (JE) is one of the most important viral encephalitis, caused by the Japanese encephalitis virus (JEV). The function of non-structural protein 2B (NS2B) mostly remains unclear. In our study, NS2B of Japanese encephalitis virus (JEV) was expressed in Escherichia coli and purified by dialysis. After fusing mouse myeloma cell line SP2/0 with spleen lymphocytes from NS2B protei...

Japanese encephalitis (JE) is one of the most prevalent global viral encephalitis viruses. The functions of JEV (virus) NS4B protein are still under investigation. In our study, NS4B was expressed in Escherichia coli and purified by dialysis. Two clones of monoclonal antibodies (MAbs 1B1 and 1C3) against NS4B protein were generated and their characterizations were investigated. IFA, Western blo...

OBJECTIVES To review past and present patterns of occurrence of Japanese encephalitis in Hong Kong and across Asia. A better understanding of the disease should facilitate the formulation of an effective strategic plan to prevent a future epidemic. DATA SOURCES Report of local cases, and literature search of MEDLINE up to November 2004. STUDY SELECTION Literature and data related to Japanes...

BACKGROUND & OBJECTIVES Japanese encephalitis (JE) is an important aetiology of acute encephalitis syndrome in Gorakhpur division, Uttar Pradesh, India. Two doses of JE vaccine ( first during 9-12 months and second during 16-24 months of age) are administered under the Universal Immunization Programme. We conducted surveys to estimate the coverage of JE vaccine and magnitude of missed opportuni...

PURPOSE Acute disseminated encephalomyelitis (ADEM) is a monophasic demyelination disease of central nervous system (CNS) with presentations of impaired consciousness, neurologic deficits and diffuse white matter lesions on magnetic resonance imaging (MRI). Predisposing infection can be identified in around 50 to 77% of all patients with ADEM. Post-infectious autoimmune events associated with J...
