In areas where malaria is endemic, donors may be screened for malaria parasites to prevent the spread of the disease.

Blood donor screening for malaria is a crucial step in ensuring the safety of the blood supply, especially in areas where malaria is endemic or has been previously transmitted. Malaria is a parasitic infection caused by Plasmodium species, and it can be transmitted through blood transfusions if the donor has a current infection or recently cleared the infection.

In regions where malaria is a concern, donors’ blood samples may undergo specific testing for malaria parasites using diagnostic methods like microscopy or rapid diagnostic tests (RDTs). These tests detect the presence of Plasmodium parasites in the blood.

It’s important to note that malaria screening and donor deferral policies may vary by location and blood donation organization. The aim is to prevent the transmission of malaria through donated blood, as even low levels of the parasite can pose a risk to recipients, particularly those with weakened immune systems.
