Characterization of occult hepatitis B in highrisk populations in Kenya
(PLOS ONE, 2020)Occult hepatitis B infection (OBI) is defined as the presence of hepatitis B virus (HBV) DNA in the liver or serum in the absence of detectable HBV surface antigen (HBsAg). OBI poses a risk for the development of cirrhosis ... -
Characterization of occult hepatitis B virus infection among HIV positive patients in Cameroon
(BioMed Central, 2017)Purpose: Occult hepatitis B infection (OBI) among HIV positive patients varies widely in different geographic regions. We undertook a study to determine the prevalence of occult hepatitis B infection among HIV infected ... -
Evolutionary Pattern of the Hemagglutinin Gene of Influenza B Viruses Isolated in Kenya 2005-2009
(African Journal of Health Sciences, 2011-06-17)Background: In humans, the inability to provide lasting protection against influenza B virus infection is due, in part, to the rapid evolution of the viral surface glycoprotein, haemagglutinin (HA), which leads to a change ... -
