[Epidemiological investigation of blood transfusion - induced malaria caused by an imported case with Plasmodium falciparum infection].

OBJECTIVE

To analyze a case infected with Plasmodium falciparum due to blood transfusion in Taizhou City, so as to provide scientific evidence for malaria control.

METHODS

The epidemiological investigation of a case with P. falciparum malaria was conducted, and the blood donors'blood samples were collected and detected in laboratory to identify the origin of the infection.

RESULTS

Microscopy detected Plasmodium in the blood samples from a 64-year-old male inpatient with nephropathy, and P. falciparum malaria was diagnosed. The case had no history of travel to Africa or Southeast Asia except blood transfusion, and he had received blood transfusion 14 times during his hospital stay. Detection of blood donors'blood samples showed P. falciparum in the archived blood samples from an Indonesian student studying in China, as revealed by PCR assay, and the student was found to have a history of malaria.

CONCLUSIONS

The patient was confirmed to be a case with P. falciparum malaria due to blood transfusion. Screening of malaria should be intensified in blood donors to prevent the development of malaria transmitted by blood transfusion.
