EPID Introduction to Analysis and Interpretation of HIV/STD Data Introduction: STDs and HIV—a brief background Manya Magnus, Ph.D. Summer 2001

Objectives To briefly describe magnitude of STD and HIV problem in the United States To discuss relationship between classical STDs and HIV

Magnitude of the problem Annual global incidence of curable STDs is 333 million cases The top four most common are gonorrhea (62 million), chlamydia (89 million), syphilis (12 million) and trichomonas (170 million) An estimated 250 million new infections occur each year 15 million new cases diagnosed annually in the United states 3 million of these cases in US are teenagers Annual cost of major STDs in US: almost $17 million

HIV/AIDS Relationship between classical STDs and HIV Increases in HIV transmission in presence of STDs. –Increased genital track shedding of virus (transmission) –Increased attraction of CD4+ lymphocytes to mucosa (transmission) –Micro-abrasions of genital tissue  increased portals of entry/exit (transmission/acquisition) –Increased attraction of CD4+ lymphocytes to mucosa (acquisition)
