The Centers for Disease Control and Prevention (CDC) collects data from state health departments in the United States and has published information regarding prevalence of STDs, including chancroid, since 1941, when 3,384 cases were reported. Starting in 1994, a significant decrease in the number of chancroid cases was reported. Only 782 cases were recorded in 1994 and steadily decreased over the following years. In 2010, 24 cases were reported from 9 different states, while, in 2013, only 10 cases of chancroid were documented. [21] In 2017, a total of 7 cases were reported. [22]

In the past, the disease was considered endemic in several large US cities but is currently seen in sporadic cases associated with low socioeconomic status, poor hygiene, prostitution among sex workers, and drug abuse. The true incidence is difficult to determine and is probably underestimated because of unavailable diagnostic resources and because of the difficulties in culturing H ducreyi, even when laboratory resources are available.
