Abstract: Chancroid, a disappearing disease in the United States, was reintroduced into the country in 1980 by immigrants from the Caribbean, Mexico, and Southeast Asia. Point epidemics resulted, each of them associated with prostitution. During the 4-month period between March 1 to June 30, 1985, forty-five patients were diagnosed and treated in Massachusetts, thirty-seven from Boston alone. By means of these case records, the morphologic characteristics, laboratory diagnosis, and treatment regimens are described.
Output:
The diagnosis and treatment of chancroid.
