Case Information

ABCs personnel complete a standardized case report form on all identified cases. This form contains questions on

Basic demographics
Underlying conditions
Vaccinations
Risk factors for infection

Surveillance personnel obtain some of the data of interest from the microbiology laboratories. However, all data that are essential for describing the population-based epidemiology of these diseases may not be available in many microbiology laboratories. Therefore, ABCs sites collect patient medical records data to complement laboratory information. Sites obtain medical records data through the cooperation of on-site hospital personnel (e.g., infection preventionists) or through medical record review by county health department personnel or ABCs personnel. Surveillance areas regularly assess the completeness of information collected for each case. If any of the core variables are frequently incomplete, ABCs sites revise the data collection methods to correct the problem.

Isolate Collection

ABCs sites collect sterile site isolates for each identified case of group A Streptococcus, Haemophilus influenzae, Neisseria meningitidis, and Streptococcus pneumoniae when available. Some sites collect group B Streptococcus isolates. Sites batch isolates and send them to CDC for further testing and characterization.
