Prevalence of antibodies to hepatitis B core antigen in blood donors in the middle west region of Brazil

Serological pattern of hepatitis B virus among HBsAg negative blood donors in Alexandria, Egypt

“…A similar high frequency was found by Aguiar et al [18]. These cases were considered to be previously infected and to have become immune to HBV infection, although we need to bear in mind that the degree of protection depends on the level of anti-HBs.…”

“…This strategy has been found to markedly minimize the possibility of HBV transmission via blood transfusion [14]. On the other hand, it may lead to the exclusion of a significant number of donors' blood, as reported in Brazil where high levels of anti-HBc were recorded (up to 57%) [18]. There has recently been concern about "anti-HBc only" or isolated antiHBc individuals, i.e.…”

Seropositivity for hepatitis B virus, vaccination coverage, and vaccine response in dentists from Campo Grande, Mato Grosso do Sul, Brazil

“…The present study showed that seropositivity for HBV infection among dentists (10.8%) from Campo Grande, MS, was higher than that recorded among blood donors (9.4%) in the same city (Aguiar et al 2001). In dentists from the other regions of Brazil, the infection rates ranged from 10 to 17.9% (Ozaki et al 1998, Camilo 1998, Rodrigues 2002.…”

Low prevalence of hepatitis B and C markers in a Non-Amazonian indigenous population

“…There are discrepancies between our data and findings previously reported for the same region. Aguiar et al [8] found prevalence rates of 0.7%, 9.4% and 2.5% for HBsAg, anti-HBc and anti-HCV, respectively among first-time donors in Campo Grande. In a study of people of African descent living 65 km from Campo Grande and 40 km from the municipality of Jaraguari (Mato Grosso do Sul), Castro [9] found rates of 9% and 43% for HBsAg and antiHBc, respectively.…”
