Yes, chlamydia rose by more than 25% in the 65+ crowd, from 887 cases in 2008 to 1134 in 2012, as it rose across all age groups by a similar rate—reflecting broader testing as promulgated by newer public health recommendations and more accurate, easier to perform tests.

But in the data I looked at, rates of gonorrhea stayed the same at about 650 cases a year while syphilis rose only slightly from a numeric perspective—from 105 to 123,—a whopper of an increase if looking at rates but it’s 18 cases over 5 years using a diagnostic test that captures decades-old untreated cases (latent disease) as well as fresh infection.
