The Morbidity and Mortality Weekly Report (MMWR) is a weekly epidemiological digest for the United States published by the Centers for Disease Control and Prevention (CDC). It was originally established as Weekly Health Index in 1930, changing its title to Weekly Mortality Index in 1941 and Morbidity and Mortality in 1952. It acquired its current name in 1976. It is the main vehicle for publishing public health information and recommendations that have been received by the CDC from state health departments. Material published in the report is in the public domain and may be reprinted without permission. , the journal's editor-in-chief is Charlotte Kent.
As noted in the sequel, some single reports have evoked media interest also outside health and medical contexts. However, many reports are parts of series, providing consistent long-term statistics, and also indicating trend changes. Such a standing report section is the "Notifiable Diseases and Mortality Tables", which reports deaths by disease and state, and city for city, for 122 large cities. As another example, there are more than a hundred items about West Nile virus infections since the 1999 outbreak of the disease in the US. In 2001–2005, there were weekly updates of the WNV situation, during the warm seasons.
Publication history
MMWR has its roots in the establishment of the Public Health Service (PHS). On January 3, 1896, the Public Health Service began publishing Public Health Reports. Morbidity and mortality statistics were published in Public Health Reports until January 20, 1950, when they were transferred to a new publication of the PHS National Office of Vital Statistics called the Weekly Morbidity Report. In 1952, NOVS changed the name of this publication to the Morbidity and Mortality Weekly Report, which continues through the current day (2020).
Notable articles
Several notable articles have been published in the report including: The spread of hepatitis A among attendees of jam band concert tours (September 2003). Several dozen deaths in teens participating in what is called the "choking game" (February 2008) A report about the elevated death rate among fishermen in the Pacific Northwest (April 2008) Improvements in public health after the implementation of municipal smoking bans (January 2009) The initial reports of a novel swine flu virus which led to the 2009 flu pandemic (April 24, 2009)
On the other hand, there have been articles that have been controversial, such as a report stating a low concerns for risks of elevated blood levels of lead in Washington, DC (April 2004). The article was notable and later criticized for not emphasizing the risks, and now is available together with two amending "notices to the readers" by CDC from 2010.
First report of AIDS
Five cases of Pneumocystis carinii pneumonia (PCP) were reported in what turned out to be the first reporting of AIDS in the medical literature (June 5, 1981). Los Angeles-based general practitioner Joel Weisman and immunologist Michael S. Gottlieb of the UCLA Medical Center had encountered a series of gay male patients with symptoms that appeared to be immune system disorders including significant loss of weight and swollen lymph nodes, accompanied by fever and rashes, in addition to two patients with chronic diarrhea, depressed white blood cell counts and fungal infections. Gottlieb diagnosed these and a number of his other patients as having pneumocystis pneumonia. A report they jointly wrote and published in the June 5, 1981, issue of Morbidity and Mortality Weekly Report, described their patients as "5 young men, all active homosexuals, [who] were treated for biopsy-confirmed Pneumocystis carinii pneumonia at 3 different hospitals in Los Angeles, California" of which "[t]wo of the patients died" by the time of the original report. This notice has been recognized as the first published report marking the official start of the AIDS pandemic and as "the first report on AIDS in the medical literature".
