Evolutionary trends in the prevalence of anti-HDV antibodies among patients positive for HBsAg referred to a national laboratory in Cameroon from 2012 to 2017

Abstract

Objective: The aim of this study was to update the data on the prevalence of anti-HDV antibodies in Cameroon. Results: Antibodies against hepatitis Delta virus (Anti-HDV) were found in 16.48% (95% CI 11.46-18.77%) of 426 hepatitis B virus surface antigen positive patients in Cameroon. Remarkably, they were significantly higher among people over 40 years and those living in the East and South regions of Cameroon at 66.7%, 50%, and 40%, respectively. These results suggest that older age and living in areas in the dense forest may be risk factors for Hepatitis D infection.
