Explanation of Condition

These infections have very high death rates and there is evidence that the virus may persist for some time after recovery. The 2014-2016 outbreak of Ebola in West Africa has increased understanding about the persistence of the virus in affected individuals and the number of asymptomatic individuals who may be able to transmit the virus to others. There is no routine screening test for EBOV currently available. There is an option to test donors serologically for the presence of anti-EBOV (antibodies) two months after the exposure event if a test becomes available. A reactive test would result in permanent deferral, a negative test would allow donation to proceed. Designated medical officers may seek expert advice where necessary, under exceptional circumstances. There is evidence of persistent virus in individuals who recover from several forms of Viral Haemorrhagic Fever. For this reason, it is necessary to defer the sexual partners of these individuals.
