ABSTRACT
@#Abstract Objective To analyze the epidemiological characteristics, prevention and control strategies, measures and the effects achieved of malaria in Huangshi City from 1951 to 2021, and to offer a reference for further strengthening malaria eradication and control successes. Methods Descriptive epidemiological methods were used to assess the prevalence, measurements, and impacts of malaria in different time periods based on data for malaria control in Huangshi City from 1951 to 2021, and we created "semi-log" line graphs and charts to display the prevalence of disease and the effort done in prior years in terms of prevention and control. Results Between 1951 and 2021, 527 780 cases of malaria were recorded in Huangshi, with an average annual incidence rate of 40.07/10 000. The prevention and control of malaria has gone through four stages, namely, the high prevalence of malaria stage (1951-1979), the basic elimination stage (1980-1999), the consolidation stage (2000-2010), and the eradication stage (2011-2021). Different strategies and measures have been adopted in different epidemic periods. During the high epidemic period, great efforts have been made to carry out general surveys and treatments, and strengthen the management of symptomatic patients; during the eradication stage, prominent and classified prevention and control strategies were adopted. When the incidence rate dropped to below 1/10 000, the main measures adopted were malaria monitoring, including timely discovery and standardization of infectious sources, disposal of epidemic points, management of migrant population malaria and vector monitoring. Through active prevention and control, remarkable results were achieved, and the incidence rate of malaria fell to below 1/10 000 in 1989, reaching the level of "basic elimination of malaria" issued by the Ministry in 1999, and passed the provincial malaria elimination acceptance in 2015. In recent years, with the increasing labor exports and foreign exchanges, imported malaria has been on the rise. African countries are the main sources of imported malaria, and the main species is P.falciparum. Conclusions Malaria was once one of the main infectious diseases endangering the health of people in Huangshi City. The preventive and control methods and procedures adopted in different epidemic periods are effective. Currently, we have entered the consolidation phase of malaria elimination, with the focus of work being to monitor, report, and timely and effectively respond to imported malaria cases, thus reducing the risk of local transmission.
