Cases are first identified through reports of infectious diseases and conditions from the local level to the state or territory.
These references provide additional information on surveillance and epidemiologic concerns, diagnostic concerns, and infectious disease-control activities.
The Summary of Notifiable Infectious Diseases and Conditions — United States, 2015 (hereafter referred to as the summary) contains the official statistics, in tabular and graphical form, for the reported occurrence of nationally notifiable infectious diseases and conditions in the United States for 2015.
Unless otherwise noted, data are final totals for 2015 reported as of June 30, 2016.
The Highlights section presents noteworthy epidemiologic and prevention information for 2015 for selected infectious diseases and conditions and additional information to aid in the interpretation of surveillance and infectious diseases and conditions-trend data.
Part 1 contains tables showing incident (new) cases and incidence rates for the nationally notifiable infectious diseases and conditions reported during 2015; these tables do not include rows for conditions with zero cases reported in 2015 (Tables 1, 2, 3, 4, 5, 6, and 7).* The tables provide the number of cases reported to CDC for 2015 and the distribution of cases by geographic location, MMWR month (MMWR month is based upon MMWR year and week, which is described in the Interpreting Data section of this report), and demographic characteristics (e.g., age, sex, race, and ethnicity).
