TB/HIV co-infection

A person not infected with HIV usually has some natural immunity against tuberculosis. However, the HIV-infected person will be more vulnerable to infection because they will have lost some of their natural immunity. This provides the TB bacteria with a favourable environment in which to multiply and bring about the full disease, showing all the common signs and symptoms. Raising awareness of TB/HIV co-infection is an important role for all health workers (Figure 16.2).
