{"title":"Assessing the Relationship Between Entomological Surveillance Indices and West Nile Virus Transmission, United States: Systematic Review.","authors":"Thomas C Moore, Xin Tang, Heidi E Brown","doi":"10.1089/vbz.2024.0072","DOIUrl":"10.1089/vbz.2024.0072","url":null,"abstract":"<p><p><b><i>Background:</i></b> Entomological surveillance indices are used to estimate the risk of West Nile virus (WNV; family Flaviviridae, genus <i>Flavivirus</i>) transmission. To determine when and where to initiate mosquito control activities, integrated vector management programs establish action thresholds based on entomological surveillance indices. However, the application of entomological surveillance indices needs further investigation relative to the human risk of WNV infection. Herein, we examine the evidence from studies that investigated the quantitative relationship between entomological surveillance indices and human WNV cases using systematic review methods. <b><i>Results:</i></b> Across three databases, 5378 articles were identified. Using the selection criteria, 38 studies were included for study. Most articles explored entomological indices weekly and devised unique geographic scales to aggregate human and/or mosquito data. The most used models were logistic and negative binomial regression. Maximum likelihood estimates (MLEs) and vector index (VI) demonstrated the greatest ratio of number of positive results to number of times tested. Among all selected articles, 35 unique U.S. locations assessed MLE and/or VI. Human WNV infection had a significant association with MLE across 81.25% (13/16) of locations. VI showed successful performance across 80.00% (24/30) sites tested. <b><i>Conclusions:</i></b> This systematic review identifies methods for quantifying relationships between entomological and human WNV infection data. We found entomological surveillance indices applied to human WNV risk should include a measure of virus presence, such as MLE and VI. Model type and covariates were too variable to identify geographic or species-specific trends, though, when tested, including temperature, land cover, population density, and time improved the model.

In this research, a literature review and meta-analysis are presented on the surveillance studies of the H9 subtype of avian influenza in wild birds worldwide up to 2024. <b><i>Methods:</i></b> A comprehensive search strategy was employed, utilizing the China Science and Technology Journal Database, China National Knowledge Infrastructure, PubMed, Google Scholar, and Scientific Direct databases. The exclusion criteria for this study included duplicate studies, reviews, other host studies, as well as research with inconsistent or insufficient data.

This systematic review aims to consolidate existing literature on DNA extraction from ticks, evaluate the various methodologies, challenges, and research gap. <b><i>Methodology:</i></b> A systematic review of existing literature was conducted to assess the efficacy, yield, and purity of DNA extracted from various tick species using the aforementioned methods. Comparative analyses focused on factors such as extraction efficiency, contamination issues, and the impact of tick exoskeleton resilience. <b><i>Results:</i></b> Phenol-chloroform extraction achieved high DNA yields (50-100 ng/µL) but posed safety risks and was time-consuming.

Magnetic bead-based extraction offered rapid results with yields ranging from 20 to 70 ng/µL, although it faced challenges such as bead carryover and equipment requirements. Variability in extraction efficiency was noted across different tick species, necessitating method optimization. <b><i>Conclusion:</i></b> The review identified several critical research gaps in DNA extraction methods for tick-borne disease diagnostics and research. Currently, methods such as mechanical disruption combined with chemical lysis and column-based methods have shown effectiveness in extracting DNA from ticks, but they come with limitations, including high cost, labor intensity, and reduced efficiency under certain conditions. Despite their utility, these methods often face challenges in resource-limited settings or in varying environmental conditions.

Viral shedding from bats is an essential prerequisite to bat-to-human viral transmission and understanding the timing and intensity of viral shedding from bats is critical to mitigate spillover risks. However, there are limited investigations on bats' seasonal viral shedding patterns and their related risk factors. We conducted a comprehensive review of longitudinal studies on bat viruses with spillover potential to synthesize patterns of seasonal viral shedding and explore associated risk factors. <b><i>Methods:</i></b> We extracted data from 60 reviewed articles and obtained 1085 longitudinal sampling events.
