Abstract
To estimate the risk of transmitting human immunodeficiency virus (HIV) and hepatitis B virus (HBV) by blood transfusion. Residual risks for each of infections have been calculated from incidence cases number, rate incidence for 100,000 person-years has been estimated and multiplied by the period of mute serological window for each agent (22 days for HIV and 56 for HBV) in order to estimate the residual risk. This study shows that risk residual is 1/121 blood donations for HBV and 1/8562 blood donations for HIV. The obtained results show that the HIV and HBV transmission risk due to blood transfusion according to the present practice at the NCBT of Conakry is important.
