Prevalence of intestinal parasitic infestation, salmonellosis, brucellosis, tuberculosis, and hepatitis B among immigrant children in Glasgow

Abstract

Two hundred Asian and 100 each of African, Chinese, and Scottish children were screened for intestinal parasitic infestations, salmonellosis, brucellosis, hepatitis B antigen (HBsAg), and tuberculosis. There was a fairly high incidence of Giardia lamblia among Asian and Scottish children and of Trichuris trichiura among the Chinese. Hookworm ova were seen only in Africa children. There were no chronic carriers of Salmonella or Brucella, and no one was suffering from salmonellosis or brucellosis. Tuberculin sensitivity was found in only 4% of immigrant and 1% of Scottish children: the difference was small and neither figure suggests a continuing high incidence of tuberculosis in Glasgow. Only seven immigrant children were found to be HBsAg carriers. Among the families of these carriers there was a high incidence (84%) of HBsAg or antibody (HBsAb). The survey shows that immigrant children in Glasgow do not constitute a health hazard to the indigenous population. Moreover, severe overcrowding is not a prominent feature among the immigrant families in Glasgow but is greatest among the local Scots.
