As part of Enhanced Meningococcal Disease Surveillance (EMDS)**, additional data and isolates were collected from 45 state and 3 large jurisdiction health departments. In 2017, the population under surveillance was 319,469,805 or 98 % of the U.S. population. EMDS focuses on: (1) collecting isolates from all cases; (2) collecting complete case information, with an emphasis on college attendance for cases 15–24 years; history of sex with men for male cases ≥16 years; and HIV infection status for all cases.
