*Some cases are reportable to public health entities.  Others are not.  Some of the statistics refer to the number of reported cases.  Others are estimated
cases.  It is well known that even in the case of reportable diseases, the numbers are far under the actual frequency of infection.  Some of the estimates are
from a CDC report entitled "Tracking the Hidden Epidemics: Trends in STDs in the United States 2000."  This is available on the Internet at
http://www.cdc.gov/nchstp/dstd/Stats_Trends/Trends2000.pdf
**Many of these diseases can be spread by sexual as well as non-sexual routes.
***Much of the condom effectiveness data is available in an NIH document entitled "Workshop Summary: Scientific Evidence on Condom Effectiveness for
Sexually Transmitted Disease Prevention."  This is available on the Internet at
www.niaid.nih.gov/dmid/stds/condomreport.pdf.  The NIH Workshop
Summary says that the term "condom ineffectiveness" will be used to mean the level of protection against STDs when condoms are used consistently and
correctly."
