What is Tuberculosis?
Mycobacterium tuberculosis
-Mycobacterium
tuberculosis, the causative bacteria of Tuberculosis, is a rod shaped, aerobic
bacteria transmitted by the
sputum of infected individuals. It has an average
latent period of one to two years before it progresses to the active, or
pathogenic,
stage of the infection. This latent period is the primary cause of
the high worldwide incidence, 2 billion people infected, because it
can be
transferred during this period without anyone’s knowledge.

Current Distribution of
Tuberculosis Worldwide

As can
be seen by this map, underdeveloped countries have the highest incidence rates
of tuberculosis. Modern medicine, and in
particular antibiotics, has given
society the ability to treat and screen for tuberculosis, hence the low
incidence rates in developed
countries where this medicine is available. In
2005, South-East Asia region accounted for the greatest number of new TB cases
at
34 % of all those reported.
In sub-Saharan Africa, the new incidence rate per 100,000 individuals is the
highest, nearly doubling those in South-East Asia.
This is due to the
prevalence of HIV within southern Africa, which when coupled with increased
poverty and little or medical attention
or knowledge, causes the spread of TB to
continue unchecked.
