However, instances of HIV infection were observed in tuberculosis patients up to 70 years.
Moreover, during the last 30 years, there have been many instances of HIV education campaigns highlighting blood-borne risks in west and central Africa (Brewer, 2011), although it is uncertain how widespread and consistent these efforts have been.
In one Zimbabwean cohort, for instance, the risk of HIV rose with increasing number of sexual partners among women, but not among men [6].
For instance, certain cases of HIV could be traced back to a specific Florida dentist (Ciesielski et al. 1992).

In Cameroon for instance, the prevalence of HIV infection among those with smear-positive pulmonary tuberculosis increased from 16.6% in 1997 to about 29.3% in 2007 [ 5, 9].
For instance, the identification of HIV in 1983 and the development of the first serological test in 1985 allowed for the design and implementation of bio-behavioural studies among specific sentinel populations.
