An analysis of the contact patterns perpetuating the transmission of tuberculosis in two high incidence communities in the Cape Town Metropolitan area

Abstract

Biomedicine positively maintains that tuberculosis transmission occurs due to close contact with a diseased individual (Coovadia and Benatar, 1991). Consequently, this refers to a direct mode of transmission where individuals are at direct risk of becoming infected. It is often taken for granted that when one speaks of contact within the context of tuberculosis, one is necessarily referring to contact or interactions among tuberculosis patients and people in the community with whom they have contact of any nature. It is then assumed that tuberculosis is transmitted in this manner. However, there are also indirect modes of transmission which are often neglected to be explored, but have an equally serious effect on transmission in high incidence areas. This paper also addresses other contact patterns that are also role-players in the tuberculosis epidemic.
