According to Ezekiel J Emanuel and the New York Times

Numbers from the Centers for Disease Control and Prevention show rapid increases in S.T.D.’s among older people. Between 2007 and 2011, chlamydia infections among Americans 65 and over increased by 31 percent, and syphilis by 52 percent.

Second, older people are living longer and are in better health. As a result, they are remaining sexually active much later into life. Several major surveys, including the National Social Life, Health and Aging Project and the National Survey of Sexual Health and Behavior, report that among people age 60 and older, more than half of men and 40 percent of women are sexually active.
