Malaria control and fever management in Henan Province, China, 1992

Abstract

Henan Province, which once had the highest malaria prevalence in China, had only 318 reported cases in 1992. Our purpose was to investigate this late 'consolidation phase' of malaria control in Henan with reference to malaria surveillance. We conducted a questionnaire survey of village doctors in Shang Shi Qiao Township during the transmission period of 1992. Of the 732 recorded fever cases, 16 were probable malaria cases by clinical and treatment response criteria, but only one received a full course of antimalarials. Of the 732 patients, 61% had fever every day, 37% went for treatment the first day, 52% waited 2-3 days and 10% waited longer. One hundred and twenty-eight patients took self-medication before seeing the doctor. Blood examination was carried out in 526 (71%) fever cases but only four were positive, all for Plasmodium vivax. Our findings highlight problems relating to patient behaviour and motivation of village doctors, malaria treatment, surveillance and microscopy, rural migration, economic development and malaria transmission. All need to be considered for reforming the malaria control strategy in Henan Province.
