Donors2
Organs are viable for a maximum of four hours, so obviously, far more people are able to donate tissue than organs, but even so, there are not huge numbers of tissue donors, as one might expect. (hero777.co.za)
Yet even with a National Skin Bank, South Africa is still way under-resourced, with only 0.2% of the population registered as organ and tissue donors. (hero777.co.za)

In 2014, The Burn Care Trust, BoneSA, the Centre for Tissue Engineering (University of Tshwane), the South African Burn Society, and Satiba (South African Tissue Association), which came on board in 2015, worked together in a strategic effort to raise awareness of burns and the need for skin within the tissue banking industry. (hero777.co.za)
With major burns, the use of allograft skin reduces the heat and fluid loss as well as number of infections and pain associated with the burn wound, improving the patient's progress in the acute period. (hero777.co.za)
Skin donation in the form of homograft/allograft etc is important in order to be able to perform rapid wound coverage among patients with severe total body surface area burns. (dehdan.org)
