Many times we talk about statistics for HIV/AIDS. Very rarely, however, do we talk about statistics for the other sexually transmitted diseases (STDs). Let me review with you how common STDs are. As you will see, STDs are quite common, and there are many STDs that are more common than HIV/AIDS. Unless stated otherwise, these statistics are for the United States, and were supplied by the U.S. Centers for Disease Control (CDC). In the United States, there are an estimated 12 million cases of STDs every year, and about 25% of these cases are in adolescents.
For the latest HIV/AIDS statistics, please go to the following websites:

The following compares the number of reported cases of STDs, versus the estimated number of actual cases. As you will see, the estimated number of actual cases is greater than the number of reported cases. This is because many cases do not get reported. The statistics for 1996 show the number of cases reported in that year, not the number of cases diagnosed in that year. There are often delays from the time a case is diagnosed, to the date it is reported to the CDC. Some STDs are not reportable in all areas (meaning they are under-reported), and some STDs are not reportable at all. The estimated number of new cases per year is based on 1998 estimates given to me by the CDC. For viral STDs (for example HIV, hepatitis A, B and C, herpes, human papilloma virus (hpv), etc.), persons diagnosed in previous years are still infected today. Therefore, the total number of cases is greater than the estimate shown.
|Disease||Reported cases (1996)||Estimated new cases/year|
|HIV (not AIDS)*, **||Not reportable in all states||Not available|
|Syphilis (all stages)||52,976||101,000|
|Hepatitis C, non-A/B**||3,716||28,000|
|Human papilloma virus (HPV)***||Not reportable||500,000 to 1 million|
|Herpes simplex virus (HSV) 1 & 2****||Not reportable||200,000 to 500,000|
|Trichomonas||Not reportable||3 million|
|HTLV-I/II**||Not reportable||Not available|
|Molluscum contagiosum||Not reportable||Not available|
|Lice/Scabies**||Not reportable||Not available|
* = The estimated total number of cases of HIV is 650,000 to 900,000.
As you will notice, STDs are quite common. Conflicting statistics for these STDs (from other sources) are usually due to one or more of the following reasons:
