More than 25 diseases are primarily spread through sexual activity.The
trends for each disease vary considerably, but together these infections
comprise a significant public health problem.1
In the United States, more than 65 million people are currently living with
an incurable sexually transmitted disease (STD). An additional 15 million
people become infected with one or more STDs each year, roughly half of whom
contract lifelong infections. Yet, STDs are one of the least recognized
health problems in the country today.2
While extremely common, STDs are difficult to track. Many people with these
infections do not have symptoms and remain undiagnosed. Even diseases that
are diagnosed are frequently not reported and counted. These "hidden"
epidemics are magnified with each new infection that goes unrecognized and
untreated.3 | h***i
