CSTE, with input from CDC, makes recommendations annually for additions and deletions to the list.The list of infectious diseases and conditions considered reportable in each jurisdiction varies over time and across jurisdictions.Tables 4–7, which have been an integral component of the summary for decades, also include incidence rates.
A notifiable infectious disease or condition is one for which regular, frequent, and timely information regarding individual cases is considered necessary for the prevention and control of the disease or condition.
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).
Monitoring surveillance data enables public health authorities to detect sudden changes in disease or condition occurrence and distribution, identify changes in agents and host factors, and detect changes in health care practices.
National-level surveillance data are compiled from case notification reports of nationally notifiable infectious diseases and conditions submitted from the state, territory, and selected local health departments to CDC.
Cases are first identified through reports of infectious diseases and conditions from the local level to the state or territory.
