Abstract
What is already known on this topic?Malaria is an infectious parasitic disease transmitted by the bite of Anopheles mosquitoes and is a serious threat to human health. Surveillance of malaria vectors is part of the integrated strategy for malaria elimination in China. What is added by this report?This research supplements the population distribution, density, and seasonal fluctuation of malaria vectors in the Anopheles surveillance sites from 2018 to 2020 in China. What are the implications for public health practice?Continuous surveillance of malaria vectors is important for maintaining malaria-free status in China and for providing a scientific basis for risk assessment of malaria retransmission.
Highlights
Malaria is an infectious parasitic disease transmitted through the bite of Anopheles mosquitoes, which seriously endangers human health [1]
High malaria incidence rates have been reported from 24 provincial-level administrative divisions (PLADs) of China [2]
This study aims to describe the population distribution, density, and seasonal fluctuations of Anopheles spp. at the sentinel sites (n=18) for malaria vector surveillance from 2018 to 2020
Summary
Yuanyuan Li1; Yuan Fang; Jingbo Xue; Limin Yang; Qin Liu; Wenqi Shi; Yi Zhang1,#. This research supplements the population distribution, density, and seasonal fluctuation of malaria vectors in the Anopheles surveillance sites from 2018 to 2020 in China. This study aims to describe the population distribution, density, and seasonal fluctuations of Anopheles spp. at the sentinel sites (n=18) for malaria vector surveillance from 2018 to 2020. The statistical data of this study were achieved using information from the malaria vector surveillance system in the national malaria zero indigenous case reporting phase, 2018–2020. According to the strategy in the “National working program for malaria vector surveillance leading for malaria elimination certification in China”, lamp trapping and humanbaited tent trap methods were used to monitor the population distribution, density, and seasonal fluctuation of Anopheles vectors, and quality control was carried out by Provincial and National CDCs. Microsoft Excel software (version 2016, Microsoft, USA) was used to analyze the surveillance data.
