The Morbidity and Mortality Weekly Report (MMWR ) series is prepared by the Centers for Disease Control and Prevention (CDC).

Often called “the voice of CDC,” the MMWR  series is the agency’s primary vehicle for scientific publication of timely, reliable, authoritative, accurate, objective, and useful public health information and recommendations.

MMWR  readership predominantly consists of physicians, nurses, public health practitioners, epidemiologists and other scientists, researchers, educators, and laboratorians.

All material in the MMWR  series is in the public domain and may be used and reprinted without special permission; citation as to source, however, is appreciated.
