Morbidity and Mortality Weekly Report Definition

Weekly Morbidity and Mortality Report: Known as MMWR, this is a major weekly scientific publication produced and published by the U.S. Centers for Disease Control and Prevention (CDC). On March 30, 2004, an “MMWR message,” Blood Lead Levels in Residents of Homes with Elevated Lead in Tap Water – District of Columbia, 2004, was posted on the MMWR website. It was later published by the CDC under the title “MMWR Weekly, April 2, 2, 2004/53(12); 268–270”. [10] The lead author was Mary Jean Brown, chief of the CDC`s Lead Poisoning Division. The report “summarizes preliminary research findings that suggest that elevated levels of lead in water may have contributed to a slight increase in blood lead levels (BLLs).” The report details the background and the different types of blood tests he used, noting in particular: “All blood tests were used in this analysis.” There is no mention that test results are not available, not even in the caveats section, where other potential sources of error are discussed. HOW TO ACCESS DATA: Preliminary data is provided as tabular data in the MMWR and as tabular and micro data (person-level data files) to CDC programs responsible for the prevention and control of the specified disease or condition. Preliminary tabular data by disease, reporting area and reference week are available at www.cdc.gov/mmwr//weekcvol.html. Final case-by-case (person-level) data (1990-2000) and aggregate summary data (1951-2000) are available upon request in accordance with the Council of State and Territorial Epidemiologists (CSTE) Data Release Policy and under a special agreement with the user. DATA ACCESS: Data collection began in 1995. The first national data report is expected in December 1998. Individual situation reports and subsets of data are regularly prepared for countries submitting data to the national database. Procedures to provide additional data are being developed.

The House of Representatives requested “transcribed interviews” with seven CDC and HHS employees “to determine the extent of political interference in CDC scientific reports and other efforts to combat the pandemic, the impact of that interference on the CDC`s mission, whether that interference will continue, and what steps Congress may need to take to stop it before more Americans die needlessly.” [23] [24] Programs funded by the NCRP report incidence data to the CDC beginning with their NPCR reference year. The “NPCR reference year” is the first year of diagnosis for which a state or territorial cancer registry collected data using NPCR funds. In January 2002, the CDC received information on more than 5.3 million cases of invasive cancer diagnosed between 1995 and 1999. DESCRIPTION: The Haemophilus Influenzae PIN system collects information from all over the United States. Cases of invasive Haemophilus influenzae disease reported to CDC since 1991 via NETSS (managed by EPA and NIP) or since 1989 via multi-site active surveillance (managed by NCIP). The information collected includes demographics, symptoms of illness, isolated serotype and vaccination history. RACE/ETHNICITY: Available data on race and/or ethnicity. OMB Statistical Directive 15 uses two variable standards for reporting.
