Seasonal occurrence of Japanese encephalitis vectors in Bareilly district, Uttar Pradesh, India

Abstract

The present study provides knowledge on distribution of JE vector in Bareilly which indicates that the area is at risk of JE outbreak. Abundance of Culex vector clearly demarcates possible threat of JE incidence in the study area. A long-term entomological study is needed to further evaluate the significant role of different weather variables in shaping mosquito densities.

Spatio‐temporal epidemiology of Japanese encephalitis virus infection in pig populations of eastern Uttar Pradesh, India, 2013–2022

“…These cyclical waves are also consistent with the expected dynamics of an endemic infectious disease, in which regular epidemic waves occur as the proportion of susceptible pigs in a population increases through births – it does not indicate necessarily that an infection is non‐immunizing although this can contribute to the effect. Generally, seroprevalence peaks were higher, or arose from a higher baseline, in the monsoon period, indicating a seasonality which has been shown previously (Borah et al., 2013; Kumari & Joshi, 2012; Pantawane et al., 2017; Singh, Kharya, et al., 2020). In the monsoon season, temperature is warmer and rainfall is higher, providing mosquitoes with more breeding habitat and promoting shorter developmental cycles.…”
