| Additional Information | Hepatitis A is spread by the faecal-oral route and by sewage-contaminated food and water. It can also be spread sexually. There is no long term infection with the virus but there are many reports of transmission by transfusion. Infection may be symptom free but can be serious and occasionally fatal. The Blood Services do not test for this infection.
Blood services may screen for hepatitis A infection using a test for hepatitis A virus RNA. Donors who are diagnosed with hepatitis A infection during pre-donation screening (i.e. before the recipient has started transplant conditioning therapy) or as part of an outbreak investigation must be deferred for 6 months, even if they do not have any symptoms of the disease. After six months, they may donate without further testing.
Rarely, a donor may test positive for hepatitis A infection on the day of donation, after the recipient has already started transplant conditioning therapy. The Transplant Centre must then carry out an immediate clinical risk assessment regarding the risk of using the donation. Sometimes, when no good alternative HPC donor is available in a timely manner, the risk to the recipient from using the donation may be less than a significant delay to transplant to attempt to source an alternative donor. |
