Active Bacterial Core Surveillance (ABCs): Emerging Infections Program Network
Print-friendly version of this surveillance report [1 page]
¶Surveillance Note
At the start of this surveillance year (2010), missing race (n=15) and deaths (n=3) data were multiply imputed using sequential regression imputation methods. Previously, missing race data were distributed in the same proportion as known cases. For comparison, view the 2010 surveillance report based on the previous method.
ABCs Areas
California (3 county San Francisco Bay area); Colorado (5 county Denver area); Connecticut; Georgia; Maryland; Minnesota; New Mexico; New York (15 county Rochester and Albany areas); Oregon; Tennessee (20 counties)
ABCs Population
The surveillance areas represent 41,981,509 persons.

ABCs Case Definition
Meningococcal disease: isolation of Neisseria meningitidis from normally sterile site in a resident of a surveillance area in 2010.
ABCs Methodology
ABCs personnel routinely contacted all microbiology laboratories serving acute care hospitals in their area to identify cases. Standardized case report forms that include information on demographic characteristics, clinical syndrome, and outcome of illness were completed for each identified case. Serogrouping of meningococcal isolates was done at CDC. Regular laboratory audits assessed completeness of active surveillance and detected additional cases.
All rates of meningococcal disease were calculated using population estimates for 2010. For national estimates of cases, race- and age-specific rates of disease were applied from the aggregate surveillance area to the age and racial distribution of the 2010 U.S. population for 49 states (excluding Oregon due to an outbreak of serogroup B disease). The Oregon reported cases were then added to obtain the national estimates. Cases with missing data, excluding ethnicity, were multiply imputed using the sequential regression imputation method.¶
