Clinico-epidemiological characteristics of hospitalized acute encephalitis syndrome children and their correlation with case fatality rate

Acute Encephalitis Syndrome (AES) in children contributes considerable morbidity and mortality in endemic region. A study was conducted to see the clinico-epidemiological characteristics of hospitalized AES children and to find out if there is any correlation of clinico-epidemiological factors with case fatality rate (CFR). This hospital-based observational prospective study was conducted in a tertiary care teaching hospital of Assam, India from 16 May, 2019 to 15 May, 2020. We enrolled clinically diagnosed 140 hospitalized AES children consecutively as per WHO case definition. Cerebrospinal fluid and serum samples were tested for JEV-specific IgM antibodies. Out of 140 AES children 84 (60%) were male and 5-12 years age group had the highest 79 (56.4%) number of cases. Primarily cases were from rural areas 132 (94.3%). In addition to fever, major clinical manifestations were seizures 114 (81.4%), altered sensorium 128 (91.4%), meningeal signs 62 (44.3%), and
