Risk Category explanation
A: Countries where the malarial risk is present in the whole country all year or with very clear seasonal guidance.
B: Countries where only parts of the country are affected.
C: Only part of the country is affected in discrete pockets, or the risk of infection is low, or that there are few visitors to the affected areas. It is likely that tourists who visit these countries will be able to donate but individual assessment must be applied. Donors are likely to have detailed knowledge of the malarial areas visited. Healthcare professionals should establish whether the donor sought advice prior to travel and if they were advised to take anti-malarial precautions.
