| Obligatory | Must not donate if: Less than two weeks from an episode of pyrexia. |
| Discretionary | If related to a common cold or other upper respiratory tract infection from which the donor is now recovered or recovering, accept. |
| See if Relevant | Infection - General |
| Additional Information | A raised temperature may be a sign of an infection, which could be passed on through a donation. Waiting two weeks from when the temperature returns to normal reduces the risk of infection being transmitted by the donation. There is no evidence that common colds and upper respiratory tract infections can be passed on by donation but it is still necessary to wait until any such infection is obviously getting better before allowing donation. |
