(Accessible Version: https://wonder.cdc.gov//nndss/static/2018/44/2018-44-figure1.html)

The figure is a bar chart showing selected notifiable disease reports for the United States with comparison of provisional 4-week totals through November 3, 2018, with historical data. Reports of acute hepatitis A, legionellosis and measles increased with acute hepatitis A, legionellosis and measles increasing beyond historical limits. Reports of giardiasis, acute hepatitis B, acute hepatitis C, meningococcal disease, mumps and pertussis decreased with pertussis decreasing beyound historical limits.

* Ratio of current 4-week total to mean of 15 4-week totals (from previous, comparable, and subsequent 4-week periods for the past 5 years). The point where the hatched area begins is based on the mean and two standard deviations of these 4-week totals.

Notes:

These are weekly cases of selected infectious national notifiable diseases, from the National Notifiable Diseases Surveillance System (NNDSS). NNDSS data reported by the 50 states, New York City, the District of Columbia, and the U.S. territories are collated and published weekly as numbered tables. Cases reported by state health departments to CDC for weekly publication are subject to ongoing revision of information and delayed reporting. Therefore, numbers listed in later weeks may reflect changes made to these counts as additional information becomes available. Case counts in the tables are presented as published each week. See also Guide to Interpreting Provisional and Finalized NNDSS Data.
Weekly tables since 1996 are available on CDC WONDER.
Weekly tables since 2014 are available on Data.CDC.gov.
Weekly tables for 1952–2017 published in the Morbidity and Mortality Weekly Reports (MMWR) are available at CDC Stacks MMWR, and weekly tables starting in 2018 are available at CDC Stacks NNDSS (once in CDC Stacks NNDSS select "Weekly Tables" in the "Genre" box at the left).
Notices, errata, and other notes are available in the Notice To Data Users page.
