Background: Japanese encephalitis virus (JEV) is a flavivirus related to dengue, yellow fever and West Nile viruses, and is spread by mosquitoes. JEV is the main cause of viral encephalitis in many countries of Asia with an estimated 68000 clinical cases every year. Although symptomatic Japanese encephalitis (JE) is rare, the case-fatality rate among those with encephalitis can be as high as 30%. Permanent neurologic or psychiatric sequelae can occur in 30-50% of those with encephalitis. This study was conducted to find the incidence of JEV IgM in patients presenting with acute encephalitis syndrome (AES) in Raiganj govt. medical college and hospital, Uttar Dinajpur, West Bengal, India.Methods: Blood and CSF samples were collected from patients presenting with AES. IgM antibody capture ELISA was performed on the CSF and serum samples by JE virus MAC ELISA kit.Results: The overall prevalence of JEV IgM was 13.8%. Among the positive cases male comprised of 71.4% and female 28.5%. The most common age group affected was above 16 years of age. JEV prevalence was present throughout the year with high number of cases between the monsoon and post monsoon seasons.Conclusions: This study demonstrates the endemicity of JEV in Uttar Dinajpur district of West Bengal, India. As most of the JE cases are asymptomatic strengthening the existing surveillance system is required to find out the actual scenario of JEV in West Bengal. Control of vectors, early diagnosis and treatment, vaccinations are the key to decrease the morbidity and mortality caused by JEV.

Emerging viruses causing Acute Encephalitis Syndrome (AES) can be more damaging due to irreversible brain damage, irrespective of the identical medical characteristics created by all agents. We report two cases of acute encephalitis syndrome caused by Japanese encephalitis virus from a usually under-reported geographic region of India. Both patients were managed conservatively with favourable outcome in one of them.There should be considerable effort to identify the particular causative agent that triggers AES, bearing in mind the various clinical manifestations of Japanese encephalitis virus. Although there is no significant impact on management, it is possible to prevent transmission to healthy contacts and the community through vector control and vaccination.

Objective: Acute encephalitis syndrome is a cause of significant morbidity and mortality in Nepal. Although Japanese encephalitis virus (JEV) was thought to be a major cause for acute encephalitis syndrome, more non-Japanese encephalitis virus cases are reported. The outcome of patients with acute encephalitis syndrome is variable. Our study was designed to study the clinical profile and outcome of patients with acute encephalitis syndrome managed in tertiary care center in central Nepal. Methods: The record of patients admitted with diagnosis of acute encephalitis syndrome,from January 2010 to December 2010 in College of Medical Sciences-Teaching Hospital (CMS-TH) was reviewed. They were classified clinically as meningitis, encephalitis and meningoencephalitis. The clinical details and reports of the patients were recorded and analyzed. Results: Total of 85 cases of meningitis and encephalitis were identified. Mean age was 19.18 years. Fifty-six (65.9%) patients were males and 29 (34.1%) were females. Sixty (70.58%) patients had meningitis, 8 (9.41%) had encephalitis, and 17 (20.0%) had meningoencephalitis. JE serology was positive in 4 patients (4.7%). Seventy-two (84.7%) patients made full recovery and were discharged from hospital. Thirteen (15.3%) patients left against medical advice (LAMA). Conclusion: Acute encephalitis syndrome is still a major public health problem in Nepal. Few of these patients have Japanese Encephalitis. There is a trend towards improved outcome because of availability of improved health services. However, financial constraint remains a challenge in management of acute encephalitis syndrome.

This is a hospital based retrospective study, which was done in Pediatric ward of Patan hospital. Study period was one and half year (from Srawan 2063 to 2064 poush).Data were taken from discharge book of Pediatric ward, from the record section of this hospital, and from JE surveillance office, WHO, Kathmandu. All children from 1 month to 14 years ,who were admitted in Pediatric ward with symptoms of Meningitis, Meningoencephalitis and Encephalitis were included in this study and patients more than 14 years of age and symptoms not suggestive of meningitis, meningoencephalitis or encephalitis were excluded from the study. Headache; vomiting and fever were the chief complaints of patients. Two patients died during study period. There were 16 patients with serologically confirmed Japanese encephalitis. Key words: Japanese encephalitis virus (JEV), arthropod borne disease, Acute encephalitis syndrome (AES).   doi:10.3126/jnps.v29i1.1595 J. Nepal Paediatr. Soc. Vol.29(1) p.17-21
