    Impact of social interactions in the community on the transmission of tuberculosis in a high incidence area
    (BMJ Publishing Group, 1999) Classen, Collette N; Warren, Robin; Richardson, Madeleine
    Tuberculosis (TB) is transmitted by close contact with an infectious person. It is assumed that close contact occurs amongst household members and that contact outside the house is �casual� and does not play a major role in the transmission of TB. This study was conducted in an impoverished area with a high incidence of TB and a low HIV seropositive prevalence. Thirty three households with 84 TB patients were identified between February 1993 and April 1996 and the transmission of TB was studied by combining Mycobacterium tuberculosis fingerprinting with in depth sociological interviews.
