||The characteristics of tuberculosis as a community
||Bhore Committee Report 1946, 1, p.98-99.
The main features of TB as a community problem
are well known. Its incidence is rare among people who lead an open
air life and among those who live in small communities, but it increases
in proportion to the degree of overcrowding. Among other factors
contributing to the spread of the disease, mention may be made of
malnutrition and undernutrition, unhygienic housing and environmental
conditions and, certain occupations, particularly those associated
with the inhalation of dust containing fine particles of silica.
No age, sex or race is exempted from TB. In countries
where the disease has been prevalent for a long time, susceptibility
to infection is highest among infants and a varying measure of protection
becomes developed as the years go by, through small doses of infection
being picked up by most individuals. For instance, only a small
proportion of those who get infected, in Europe and America, develop
the disease or die of it, while the majority acquire a considerable
degree of protection from it. On the other hand, in communities
exposed to TB for the first time, example, primitive races coming
in contact with persons from the highly tuberculised countries,
the disease occurs in a virulent form and the rate of its spread
is rapid. In countries with a long history of TB infection, it is
only among infants that conditions exist which approximate to those
of the highly susceptible communities.
