ERRATUM:  Weeks 1-52 data for Haemophilus influenzae, invasive disease in Table 1 were updated on Monday, February 11, 2019.
Labels for "Nontypeable" and "Non-b serotype" were incorrectly placed resulting in the numbers being switched for these two rows. They are now correct.

  • -: No reported cases — The reporting jurisdiction did not submit any cases to CDC.
  • N: Not reportable — The disease or condition was not reportable by law, statute, or regulation in the reporting jurisdiction.
  • NA: Not available — CDC does not have data because of nomenclature changes in how data are reported for nationally notifiable conditions.
  • NN: Not nationally notifiable — This condition was not designated as being nationally notifiable.
  • NP: Nationally notifiable but not published — CDC does not have data because of changes in how conditions are categorized.
  • Cum: Cumulative year-to-date counts.
  • * Case counts for reporting years 2017 and 2018 are provisional and subject to change. Data for years 2013 through 2016 are finalized.
  • † This table does not include cases from the U.S. territories.
  • § Calculated by summing the incidence counts for the current week, the 2 weeks preceding the current week, and the 2 weeks following the current week, for a total of 5 preceding years. Additional information is available at https://wwwn.cdc.gov/nndss/document/5yearweeklyaverage.pdf.
  • ¶ Not reportable in all jurisdictions. Data from states where the condition is not reportable are excluded from this table, except for the arboviral diseases and influenza-associated pediatric mortality. Reporting exceptions are available at http://wwwn.cdc.gov/nndss/downloads.html.
  • ** Since October 1, 2017, 178 influenza-associated pediatric deaths occurring during the 2017-18 season have been reported.
  • †† No measles cases were reported for the current week.
  • §§ Novel influenza A virus infections are human infections with influenza A viruses that are different from currently circulating human seasonal influenza viruses. With the exception of one avian lineage influenza A (H7N2) virus, all novel influenza A virus infections reported to CDC since 2013 have been variant influenza viruses.
  • ¶¶ Prior to 2018, cases of paratyphoid fever were included with salmonellosis cases (see Table II).
  • *** Prior to 2015, CDC's National Notifiable Diseases Surveillance System (NNDSS) did not receive electronic data about incident cases of specific viral hemorrhagic fevers; instead data were collected in aggregate as "viral hemorrhagic fevers'. NNDSS was updated beginning in 2015 to receive data for each of the viral hemorrhagic fevers listed.
