Abstract:
Abstract: Objective China was certified by World Health Organization as a malaria-free country in 2021. Malaria has become a rare infectious disease, and preventing the re-transmission of imported malaria and reducing deaths are the main challenges facing China after elimination of malaria. To analyze and clarify the characteristics of imported malaria deaths, and to provide prevention and treatment recommendations for overseas workers and health care workers. Methods The data of 17 imported malaria deaths in the analysis of malaria deaths from 2016 to 2020 by the National Severe Malaria Treatment Expert Group were collected, and the relevant clinical epidemiological data and disease course records were analyzed. Results The 17 malaria deaths were all imported from Africa with Plasmodium falciparum infection (malarial cerebral type), with no obvious regularity in the month of onset. Among them, 16 were male patients, 5 cases with underlying diseases such as diabetes mellitus, and 10 patients were first diagnosed in a second-level or lower hospital. Excluding patients who died of respiratory cardiac arrest in ambulances, the mean time difference between first onset and malaria diagnosis in 16 patients was 6.8 days (median 5.5 days), and the mean time between first onset and antimalarial treatment was 7.4 days (median 6 days), the mean time difference from initial onset to death was 10.3 days (median 8.5 days). Excluding cases with onset abroad and unknown time of return, all 14 patients developed the disease within 30 days after returning to China. Conclusion All the fatal cases were infected with Plasmodium falciparum imported from Africa. The patients' awareness of actively seeking medical treatment is weak, and the delay in seeking medical treatment caused by the insufficient diagnosis and treatment capacity of health institutions at the township level and below is the main reason for the deaths. It is recommended to strengthen the self-protection awareness of staff in malaria-endemic areas overseas and raise their awareness of malaria. For returnees from areas with high malaria risk, primary medical institutions should pay attention to the patient's travel history in Africa, improve the awareness of malaria diagnosis, malaria diagnosis and treatment capabilities.
