Transfusion-transmitted malaria (TTM) is a rare occurrence with serious consequences for the recipient. In non-endemic areas, the incidence of transmission of malaria by transfusion is very low. We report a clinical case of transfusion-transmitted malaria due to , which happened in a patient with acute hemorrhagic gastropathy.Case presentation: In April 2019, a 70-year-old Italian man with recurrent spiking fever for four days was diagnosed with a infection, as confirmed using microscopy and real-time PCR. The patient had never been abroad, but about two months before, he had received a red blood cell transfusion for anemia. Regarding the donor, we revealed that they were a missionary priest who often went to tropical regions. spp. PCR was also used on donor blood to confirm the causal link. Discussion and Conclusions: The donations of asymptomatic blood donors who are predominantly "semi-immune" with very low parasitic loads are an issue. The main problem is related to transfusion-transmitted malaria. Our case suggests that infections in semi-immune asymptomatic donors are a threat to transfusion safety. Currently, microscopy is considered the gold standard for the diagnosis of malaria but has limited sensitivity to detect low levels of parasitemia. Screening using serological tests and molecular tests, combined with the donor's questionnaire, should be used to reduce the cases of TTM.

Background And Objectives: Malaria risk deferral policies are important for mitigating the risk of transfusion-transmitted malaria and apply to all transfusable components, including plasma. While donors of plasma components are deferred for malaria risk in the United States, the viability of intraerythrocytic Plasmodium falciparum parasites present in human plasma components stored under different temperatures and durations has not been previously reported.
Materials And Methods: We spiked human plasma with a low level of ring-stage P.
Background: Despite saving a vast number of lives through blood transfusions, transfusion-transmitted infections (TTIs) still threaten the lives of people needing blood transfusion. Hence, screening blood donors and reviewing the prevalence of TTIs amongst blood donors might show the impact of these infections among our people. The aim of this study was to evaluate the prevalence rates of transfusion-transmitted infections among blood donors in Makkah as foundation for providing harmless blood transfusion in Makkah, Saudi Arabia.
