TABLE 1. (Continued) Provisional cases of infrequently reported notiable diseases (<1,000 cases reported during the preceding year) — United States, week ending November 1, 2008 (44th week)*
: No reported cases.
N: Not notiable.
Cum: Cumulative year-to-date counts.
* Incidence data for reporting year 2008 are provisional, whereas data for 2003, 2004, 2005, 2006, and 2007 are nalized. 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 http://www.cdc.gov/epo/dphsi/phs/les/5yearweeklyaverage.pdf. Not notiable in all states. Data from states where the condition is not notiable are excluded from this table, except in 2007 and 2008 for the domestic arboviral diseases and inuenza-associated pediatric mortality, and in 2003 for SARS-CoV. Reporting exceptions are available at http://www.cdc.gov/epo/dphsi/phs/infdis.htm. Includes both neuroinvasive and nonneuroinvasive. Updated weekly from reports to the Division of Vector-Borne Infectious Diseases, National Center for Zoonotic, Vector- Borne, and Enteric Diseases (ArboNET Surveillance). Data for West Nile virus are available in Table II. ** The names of the reporting categories changed in 2008 as a result of revisions to the case denitions. Cases reported prior to 2008 were reported in the categories: Ehrlichiosis, human monocytic (analogous to E. chaffeensis); Ehrlichiosis, human granulocytic (analogous to Anaplasma phagocytophilum), and Ehrlichiosis, unspecied, or other agent (which included cases unable to be clearly placed in other categories, as well as possible cases of E. ewingii). Data for H. inuenzae (all ages, all serotypes) are available in Table II. Updated monthly from reports to the Division of HIV/AIDS Prevention, National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention. Implementation of HIV reporting inuences the number of cases reported. Updates of pediatric HIV data have been temporarily suspended until upgrading of the national HIV/AIDS surveillance data management system is completed. Data for HIV/AIDS, when available, are displayed in Table IV, which appears quarterly. Updated weekly from reports to the Inuenza Division, National Center for Immunization and Respiratory Diseases. There are no reports of conrmed inuenza-associated † § ¶ †† §§ ¶¶
pediatric deaths for the current 2008-09 season. *** No measles cases were reported for the current week.
Data for meningococcal disease (all serogroups) are available in Table II. In 2008, Q fever acute and chronic reporting categories were recognized as a result of revisions to the Q fever case denition. Prior to that time, case counts were not
differentiated with respect to acute and chronic Q fever cases. No rubella cases were reported for the current week. **** Updated weekly from reports to the Division of Viral and Rickettsial Diseases, National Center for Zoonotic, Vector-Borne, and Enteric Diseases. ¶¶¶

Beyond historical limits
No measles cases were reported for the current 4-week period yielding a ratio for week 44 of zero (0).
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.
