Abstract

 Background and Objectives

 Recently a method was used for estimation of incidence rates for human immunodeficiency virus (HIV) and hepatitis C virus (HCV) among first-time donors. Since there are no published data for HIV and HCV incidence rate estimation in Iran, we planned the present study.

 Materials and Methods

 In this retrospective study, all first time blood donors (98810 donors) in two age categories (17-20 and 26-33 years old) were included for analysis. To estimate HIV and HCV prevalence rates in these age groups, the total confirmed positive test results for HIV and HCV were divided by the number of all donors at the same age group. To determine the incidence of HCV and HIV, the prevalence differences at the age groups were divided by the average age differences of the relevant groups. Data were analyzed by SPSS 19.5.

 Results

 For HIV, incidence estimates were 1.47 and 1.21 per 100000 donations in 2009 and 2010, respectively (the average 1.37 per 100000 donations for 2 years of study). For HCV, incidence estimates were 15.69 and 11.83 per 100000 donations in 2009 and 2010 (the average 13.26 per 100000 donations for 2 years of study).

 Conclusions

 Data showed that the incidence rate of HIV of blood donors is comparable to developed countries, but HCV incidence rate is higher than that of developed countries. As a matter of fact we should manage blood safety by applying other technics like NAT.
