Abstract: Infection control measures have been responsible for a decline in the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in hemodialysis patients. In Brazil, these measures have been in place since 1996. The aim of this study was to evaluate the current HBV and HCV epidemiology among hemodialysis patients in the State of Tocantins comparing them with those found 14 years ago. There was a significant decline in hepatitis B surface antigen (HBsAg) and anti-HCV prevalence from 4% and 13%… Show more

“…The point prevalence estimates varied substantially, from as high as 68.0% in a study in 1992 in Southeast Brazil (Oliveira et al, 2001) to as low as 2.8% in a study in 2014 in the North (Cordeiro et al, 2018). Studies addressing active HCV infection, i.e., consisting of patients that tested for HCV antibodies and HCV-RNA, also varied considerably, but not as much as in the previous studies.…”

“…The groups at most significant risk for infection are intravenous drug users, 7 individuals undergoing predialysis, 8 individuals with coagulation disorders, and individuals with chronic renal failure. 9 Other groups such as health waste handlers, 10 those undergoing hemodialysis, 11 incarcerated individuals, 12 and pregnant women 13 have higher prevalence rates than individuals in the general population. Despite low frequencies of HCV infection, sex workers, 14 Amerindians from six tribes in the Eastern Amazon region, 15 and military personnel 16 all have higher rates than blood donors.…”
