a) Donors who have had malaria diagnosed in the past:
If more than three years have passed since anti-malarial therapy has been completed and symptoms caused by malaria have resolved and a validated test for malarial antibody is to be performed, accept.
If the donor (with a history of malaria) has revisited a malaria endemic area and at least four months have passed since return and a validated test for malarial antibody is to be performed, accept.
b) Donors who have EVER had an undiagnosed fever that could have been malaria while in a malarial area or within four months of leaving a malaria endemic area:
If at least four months have passed since the donor returned from the malarial endemic area, or from the date of recovery from symptoms (undiagnosed fever) that may have been caused by malaria, whichever is later, and a validated test for malarial antibody is to be performed, accept.
NB. this may have to be increased to six months if the area is also identified as a risk area for T.cruzi or a tropical virus; the longest stipulated deferral period must be applied
c) Donors who have EVER been resident in a malarial endemic area for 6 months or more:
If at least four months has passed since the date of the last potential exposure to malaria, and a validated test for malaria antibody is to be performed, accept.
d) For all other donors:
If at least four months and less than 12 months have passed since return from a malaria endemic area, and a validated test for malarial antibody is to be performed, accept.
