Viral immunology
-
Globally, increased incidence of liver disease caused by hepatitis B virus (HBV) is responsible for high morbidity and mortality among human immunodeficiency virus (HIV)-infected individuals. This is because both viruses share common routes of transmission. We determined prevalence of HBV-HIV coinfection and the influence of some risk factors on concomitant infection among people living with HIV in a treatment center in Kakuri, Kaduna State. ⋯ High infection rate observed in this study underscores the need for public awareness, to educate people on modes of transmission. Routine screening is advocated for early HBV identification, as this will facilitate reduction of comorbidity and mortality resulting from opportunistic infection. Findings from this study support introduction of HBV vaccination as part of the Expanded Programme on Immunization in Nigeria.
