It was a hot summer season in the 1990s. Leizhou Peninsula was salty and humid, dry and hot, and mosquitoes were breeding. Lin, in his 20s, came to a stone quarry with a simple microscope and a medicine box on his back. The conditions in the work shed are difficult. There are no quilts or mosquito nets. The workers sleep on the ground. One of them is convulsed and holds a large stone for cooking in a pot to keep warm. He is suffering from malaria. "On a hot day in July and August, he was so cold that he shivered." More than 30 years have passed, and Lin Xianxing, an expert in malaria control at the Guangdong Provincial Center for Disease Control and prevention, can still feel the pain that flowed out of the patients' hearts. Malaria is an ancient infectious disease, mainly transmitted through mosquito bites. It is estimated that in the 1950s and 1960s, there were about 2 million to 3 million malaria cases in Guangdong every year, making Guangdong one of the provinces with the most serious malaria epidemic in China. Over the past 70 years, through the efforts of generations of malaria control workers, Guangdong successfully passed the provincial final evaluation on malaria elimination organized by the National Health Commission in March 2019, achieving the goal of eliminating malaria. In June 2021, China passed the certification of eliminating malaria by the World Health Organization, and the epidemic history of malaria in China for more than 3000 years officially ended. Recently, the National Health Commission, the General Administration of customs, the State Administration of traditional Chinese medicine and other departments jointly commended the national advanced collectives and individuals in the work of eliminating malaria. In Guangdong, 6 collectives and 14 individuals including Lin Guangxing were commended. "Anyone who has witnessed the onset of malaria will want to help him as soon as possible." This is the simple original intention of many malaria control experts to devote themselves to this cause. Widely popular?? All night long, the "human body" was used to lure mosquitoes. "The cold shiver when malaria broke out came from the heart. It didn't work to cover seven or eight quilts." At the end of the 1990s, Chen Jinfeng, who was also an intern in the eighth hospital affiliated to Guangzhou Medical University, first saw a patient suffering from malaria during the ward round. "The bed was shaken violently by him, like a boat shaking on the sea.". Before 1949, there were nearly 30 million malaria cases in China every year. In Guangdong Province, the period from 1950 to 1959 was a period of widespread malaria epidemic. The average annual population incidence rate was 183.23/10000, and the annual average reported cases reached 567500. In 1952, Guangdong Guangzhou health and epidemic prevention station was established in our province, and systematic prevention and control and Research on malaria were started. In 1956, the national outline for agricultural development clearly stated that five major parasitic diseases such as schistosomiasis and malaria should be eliminated within a time limit. First of all, it is necessary to understand the vector of malaria. Huang Qilin, former director of the parasitic disease Research Institute of the Guangdong Provincial Health and epidemic prevention station, once recalled his experience of staying in malaria endemic areas. They used people as "bait" in the countryside, mountain forests and construction sites to lure mosquitoes in the night when mosquitoes frequently appeared. Vest shorts, artificial glass straws and mosquito cages are standard for front-line personnel. Pan Bo, chief expert of the Provincial Center for Disease Control and prevention on parasitic diseases, recalled that like his predecessors, he often met his colleagues face to face when catching Anopheles mosquitoes and sat on a stool for 12 hours. When the mosquito bites itself, the first reaction is happy, "hurry up and call my colleagues to help me catch it.". They sucked mosquitoes into glass tubes with straw, and then put them into mosquito cages for anatomical research the next day.
