This announcement supports integration of diagnostic and prevention services for the Human Immunodeficiency Virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV), sexually transmitted diseases (STD); and tuberculosis (TB) because of CDC's greater understanding of the extent to which:
STDs increase the risk for HIV infection.
Control of TB, viral hepatitis, and STDs is needed to protect the health of HIV-infected persons.
HIV, viral hepatitis and STDs share common risks and modes of transmission.
Risks for acquiring theses diseases are associated with similar behaviors and environmental conditions and have reciprocal or interdependent effects.
Clinical course and outcomes of these diseases are influenced by co-infection (for example, HIV/TB can be deadly, and TB accelerates HIV disease progression).
Populations disproportionately affected by HIV are also disproportionately affected by infections with TB, HCV, HBV, and STDs.
