NNDSS - Table II. Giardiasis to Haemophilus influenza

Note

This table contains provisional cases of selected national notifiable diseases from the National Notifiable Diseases Surveillance System (NNDSS). NNDSS data from the 50 states, New York City, the District of Columbia and the U.S. territories are collated and published weekly on the NNDSS Data and Statistics web page (wwwn.cdc.gov/nndss/data-and-statistics.html). Cases reported by state health departments to CDC for weekly publication are provisional because of the time needed to complete case follow-up.

Therefore, numbers presented in later weeks may reflect changes made to these counts as additional information becomes available. The national surveillance case definitions used to define a case are available on the NNDSS web site at wwwn.cdc.gov/nndss/. Information about the weekly provisional data and guides to interpreting data are available at: wwwn.cdc.gov/nndss/infectious-tables.html.
