“…2,6,8,[28][29][30] Similar to other studies, almost one-third of our patients with JE had neurological sequelae and almost half had subjective cognitive function impairment at the six-week follow-up interview. 6,31 This finding suggests that JE may represent a substantial burden in an already impoverished country because of the resultant lack of productivity and caregiver activities.…”

Abstract. We investigated the epidemiology and etiology of encephalitis at four tertiary hospitals in Bangladesh during [2003][2004][2005]. Patients who met a clinical case definition for acute encephalitis and had cerebrospinal fluid (CSF) pleocytosis were eligible for enrollment; a standardized sampling pattern was used to enroll eligible patients. Recent Japanese encephalitis virus (JEV) infection was defined by presence of IgM antibodies against JEV in CSF or serum. Twenty (4%) of 492 cases had laboratory evidence of recent JEV infection; two died. All JE cases occurred during May-December, and cases were identified among all age groups. All cases resided in rural areas. Fifteen patients were re-assessed 4-6 weeks after hospitalization; 5 (33%) patients had physical disabilities and 7 (47%) reported cognitive difficulties. Infection with JEV is clearly an etiology of encephalitis in Bangladesh. Population-based studies to quantify burden of disease could assess options for targeted immunization programs.

“…• Incidence Group C1: Overall incidence is 3.3 per 100 000 (weighted average of results from Yin et al 20 and Xufang et al 13 ); the child to adult case frequency ratio is 3:1 (based on the ratio of 156 cases in 0-14-year-olds to 57 cases in persons aged > 14 years among combined residents and non-residents, as reported by Yin et al 20 25 Kari et al 26 and Hoke et al 27 ); the child to adult case frequency ratio is 7:1 (based on the ratio of 43 childhood cases to 6 adult cases detected from July 2001 through 2006 by Wong et al 32 ).…”

“…Each of these papers (or the English translation of five Chinese-language papers) was then carefully reviewed by at least two authors to further cull the list, resulting in a final group of 12 studies that provided original, recent population-based and largely laboratory-confirmed incidence data (or hospital-based incidence data in a defined population). 13,20,[23][24][25][26][27][28][29][30][31][32] These 12 studies consisted of one study each from Bangladesh, Cambodia, Indonesia, Malaysia and Thailand, two from China (excluding Taiwan) two from Japan and three from Nepal. They represented all but three (B, E and I) of the 10 incidence groups (Table 1).…”

“…Compared with results of previous studies, 28 the fatality rate of JE in Taiwan was very low (20-40% versus 7.1%). The lower fatality rate in Taiwan may be due to the national health insurance system, through which people have greater access to hospital services.…”

Abstract. The incidence of Japanese encephalitis (JE) decreased sharply after the national vaccination program was implemented in Taiwan in 1968. However, cases of JE still occur. The purpose of this study was to assess the epidemiology and vaccination policy for JE in Taiwan. We analyzed the data on JE cases reported to the Taiwan Centers for Disease Control (Taiwan CDC) between 2000 and 2014. During the 15-year study period, a total of 4,474 cases were reported to the Taiwan CDC. Of these, 379 (8.5%) were classified as confirmed cases, and 4,095 (91.5%) were classified as suspected cases. The incidence of JE ranged from 0.59 to 1.61 per 1,000,000 people and peaked in 2007. Men had a higher incidence of JE than women (1.37 versus 0.84 per 1,000,000; P = 0.03). Patients who were 40-59 years of age had a higher incidence than did patients younger than 20 years (1.82 versus 0.23; P < 0.001). Patients who lived in the eastern region of Taiwan had the highest incidence rate of JE (P < 0.001). Compared with those who were not vaccinated with the JE vaccine, patients who received four doses of JE vaccine had a lower risk of suffering from death and/or hospitalization (adjusted odds ratio: 0.26; 95% confidence interval: 0.08-0.90; P = 0.04). JE is still a public health problem in Taiwan, and monitoring JE via diagnostic testing to determine the best vaccination program along with enforcing JE vaccine boosters for adults is necessary to eliminate JE in Taiwan.
