High Rates of Hepatitis B and C and HIV Infections among Blood Donors in Cameroon : A Proposed Blood Screening Algorithm for Blood Donors in Resource-Limited Settings

Abstract EN

Background.

Infections with human immunodeficiency virus (HIV), hepatitis B (HBV), and hepatitis C virus (HCV) are currently major public health problems.

Methods.

A retrospective study was conducted from January to June 2008 at the Blood Bank of the Central Hospital, Yaoundé (Cameroon).

The objective was to study the prevalence of HIV, HBV, and HCV and their coinfections among blood donors.

Results.

A total of 4650 donors were identified, and the sex ratio (male/female) was 14/1.

The median age of donors was 28 years (range: 16 to 69 years).

Among blood donors, HBV, HIV, and HCV infection prevalences were 12.14% (n=565) , 4.44% (n=206), and 1.44% (n=67), respectively.

Coinfection with HIV and HBV was observed among 0.77% donors, followed by hepatitis B and C co-infection (0.21%) and HIV and HCV coinfection (0.06%).

Co-infection with HIV-HBV-HCV was encountered in 2 donors.

The HIV, HBV, and HCV infections lead to a destruction of one out of six sets of blood collected.

Conclusion.

There is a need to review policies for blood collection from donors, by modifying the algorithm of blood donors testing.

Pretesting potential donors using rapid tests could help to avoid collection and destruction of (infected) blood.
