Listeriosis (Listeria monocytogenes)
1997 Case Definition
The 1997 case definition appearing on this page was previously published in the 1990 MMWR Recommendations
and Reports titled Case Definitions for Public Health Surveillance [MMWR 1990;39(RR13)]
(available at http://www.cdc.gov/mmwr/preview/mmwrhtml/00025629.htm).
Thus, the 1990 and 1997 versions of the case definition are identical.
