Background: The biological characteristics of mosquito vectors vary, impacting their response to control measures. Thus, having up-to-date information on vector bionomics is essential to maintain the effectiveness of existing control strategies and tools, particularly as India aims for malaria elimination by 2030.
Objective: This study aims to assess the proportions of vector species resting indoors and outdoors, determine their preference for host biting/feeding, identify transmission sites, and evaluate the susceptibility of vectors to insecticides used in public health programs.
Article Synopsis
- A comprehensive entomological survey in Alipurduar District, West Bengal, conducted from 2018 to 2020 and again in 2022, focused on identifying mosquito species linked to reported malaria cases across various health centers and villages.
- Researchers employed hand-collection methods and utilized both morphological and molecular techniques, including sequencing of the mitochondrial cytochrome c oxidase gene (CO1), to accurately identify mosquito species and assess their potential as malaria vectors.
- The study identified several important mosquito species, confirming the first occurrences of certain types in West Bengal and highlighting significant human blood meal positivity, which indicates their role in malaria transmission within the region.
Background: With the reports of indigenous cases of dengue and chikungunya in the forest-covered rural tribal malaria-endemic villages of Dhalai District, Tripura, India, an exploratory study was undertaken to identify the vector breeding sites.
Methods: From June 2021 to August 2022, mosquito larvae were collected from both natural and artificial sources in the villages, house premises, and their nearby forested areas outside of the houses. Other than morphological characterisation, species were confirmed by polymerase chain reaction targeting both nuclear (ITS2) and mitochondrial genes (COI) followed by bidirectional Sanger sequencing.
Background: Bacterial meningitis is associated with significant morbidity and mortality worldwide. We aimed to describe the epidemiology, aetiology, trends over time and outcomes of laboratory-confirmed bacterial meningitis in England during 2012-2019.
Methods: UK Health Security Agency routinely receives electronic notifications of confirmed infections from National Health Service hospital laboratories in England.
