| prevalence and epidemiological characteristics of hepatitis b and c infections among doctors and dentists in nigeria. | a random sample of seventy five doctors and dentists at the university college hospital, ibadan, nigeria, was surveyed. they were offered anonymous testing for hepatitis b surface antigen (hbsag), hepatitis b e antigen (hbeag), antibodies to hepatitis b core antigen (anti-hbc) and to hepatitis c virus (anti-hcv) by enzyme immunoassay. the results suggest a high prevalence of hepatitis b virus (hbv) with a high potential of transmissibility, as well as a high prevalence of hcv infection. most of ... | 1997 | 9487396 |
| hepatitis b and c in doctors and dentists in nigeria. | we surveyed a random sample (n = 75) of doctors and dentists at university college hospital, ibadan, nigeria. they were offered anonymous testing for hepatitis b surface antigen (hbsag), hepatitis be antigen (hbeag), antibodies to hepatitis b core antigen (anti-hbc) and to hepatitis c virus (anti-hcv), by enzyme immunoassay. the results suggest a high prevalence of hepatitis b virus (hbv) with a high potential of transmissibility, as well as a high prevalence of hcv infection. the majority of th ... | 1997 | 9205680 |
