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.
