“…This could be because people from this age group actively take part in the cultivation of crop fields in rural areas. Similar findings have been reported by Chatterjee et al 10 Saha et al reported maximum number of cases belonging to the age group of 0-15 years (63.3%) which was different from our study. 12 Chakraborty et al also reported maximum number of cases in the age group under 15 years.…”

“…Other studies from West Bengal have also reported fever to be the most common presentation. 10,11 Although JE positive cases were seen throughout the year, it peaked during the monsoon and post-monsoon period. In other studies, conducted from West Bengal, authors reported that large number of cases occurred during rainy and post rainy season.…”

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.

“…According to earlier research, 31.3 percent of suspected CHIKV cases in West Bengal's various districts between 2015 and 2016 were positive for the virus [25]. Our analysis found a lower incidence of CHIKV cases (11.63%) in various areas of West Bengal.…”

The chikungunya virus (CHIKV) and scrub typhus infection has scattered worldwide creating human health hazards in India and Asia specific region. We aimed to identify chikungunya, scrub typhus, and their co-infection in dengue-negative samples having undifferentiated febrile illnesses. Enzyme linked immunosorbent assay (ELISA) methods were used to detect the chikungunya and scrub typhus specific IgM antibody by using chikungunya IgM capture ELISA kit and scrub typhus IgM Microlisa ELISA kit, respectively. OD value was measured with the help of BeneSphera (India) ELISA microplate reader. Among 490 suspected patients, 57 (11.63%) samples were tested positive for chikungunya IgM antibodies, while 43 (8.77%) came positive for scrub typhus IgM antibodies, but all samples tested negative for dengue IgM antibodies. Additionally, 5% of the total positive cases were positive for both chikungunya and scrub typhus infection. Our study offers a hypothesis regarding one of the possible causes of the decline in the frequency of scrub typhus and chikungunya cases reported in Kolkata and other districts of West Bengal. As an outcome, physicians treating undifferentiated febrile patients in endemic locations should look for chikungunya, scrub typhus, and existing coinfection between them to avoid delayed diagnosis and provide proper treatment against these infections.
