History Of

Sera from military personnel found to have antibodies to hepatitis B surface antigen (anti-HBS) in an epidemiological study of a hepatitis B outbreak were tested for persistence of that antibody 1 year later. Initially, 64% of the anti-HBS-positive sera reacted in passive hemagglutination tests with erythrocytes coated with hepatitis B surface antigen of both ayw and adw subtypes; the remaining sera reacted only with adw-coated erythrocytes (19%) or ayw-coated erythrocytes (17%). After 1 year, anti-HBS was detectable by passive hemagglutination tests in 87% of individuals with initial antibody to both subtypes but in only 41% and 16% (P less than 0.001) of those initially reacting only to adw- or ayw-coated erythrocytes, respectively. Seropositivity for anti-HBS correlated best with history of contact with jaundiced people (20.3%) and duty in Asia.

Efficiency And Effectiveness

The changes in the types and numbers of tests used by participants in the Center for Disease Control Proficiency Testing Program for the detection of hepatitis B surface antigen from the beginning of the program in 1971 until October 1975 are analyzed; the implications of these changes are discussed. Changes in the use of agar gel diffusion, rheophoresis, counterelectrophoresis, complement fixation, reverse passive latex agglutination, radioimmunoassay, and reverse passive hemagglutination tests are reviewed. The performance of the participants for 1975 is reported, and factors related to performance (type or combinations of tests used, procedures used to confirm specificity, etc.) are discussed. The increase in the use of third-generation tests in place of tests with lower sensitivity and the decrease in the use of multiple tests undoubtedly represent increased efficiency and effectiveness.

Hepatitis B virus (HBV) is a major public health problem globally and accounts for about one million deaths worldwide annually. This study determined the seroprevalence, distribution of HBV infection, and factors associated with the infection amongst patients attending selected hospitals in Niger State. A total of 500 blood samples were collected from five selected hospitals in Niger state. The samples were screened using Hepatitis B Surface Antigen (HBsAg) test kit for the qualitative detection of Hepatitis B Surface Antigen in serum. Prevalence of Hepatitis B infection was 13.0% cumulatively in the study area. Female participants had a higher prevalence (6.8%) of HBsAg infection compared to their male counterparts with 6.2%. Participants within the 41- 50 years’ age group recorded a higher rate of infection (5.2%), while those ≥ 50 years had a lower prevalence of (2.3%). The civil servants had a higher percentage prevalence of 6.4% followed by housewives and the least was observed with participants who are students. Patients without a history of blood transfusion recorded a higher percentage prevalence (7.8%) compared to those with a history of blood transfusion (5.2%). The results reveal that participants with polygamous family types recorded a higher prevalence of HBV infection (11.4%) compared to those belonging to the monogamous type (1.6%). The results obtained from this study suggest that HBV is in circulation in the study areas; thus necessitating more awareness campaigns among the general population about HBV and its modes of transmission and associated risk factors
