Clinically apparent hepatitis C virus (HCV) infection developed in a prison inmate after two tattooing episodes within the recognised incubation period for HCV infection, Seroconversion and HCV viraemia with subsequent resolution of hepatitis and loss of plasma viraemia were documented. Introducing licensed tattooists, and thereby improving infection control practices. may reduce the risk of hepatitis C virus infection in prisons.
Summary
The prevalence of antibodies in human sera from the south coast of New South Wales to four arboviruses, isolated from mosquitoes collected along the south coast, was determined in an attempt to estimate the importance of these viruses in human infection. Only two viruses, Barmah Forest and Gan Gan, were considered to be of any significance.
Summary. The sera of 468 blood donors and 63 domestic animals, collected from the south coast of New South Wales, were tested for the presence of antibodies to Ross River virus. Antibodies were detected in 7% of human sera, 25% of cow sera and 65% of horse sera. Using the blood donors as 'human sentinels', seroconversions were demonstrated in two donors from the NowraKiama region and from a patient in the same area; none of the three had been outside of the study area during the period of seroconversion or at the time of infection. Ofthe 15 seropositive horses, 6 (40%) had lived continuously since birth on the farms on which they were bled. That humans and horses were infected with Ross River and not a related alphavirus was shown by microneutralization tests against Ross River virus and the other two alphaviruses (Getah, Sindbis) known to occur in Australia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
