    ABCs case report, neonatal sepsis surveillance, neonatal infection expanded tracking, invasive MRSA case report...

  • Laboratory Characterization

    Laboratory characterization information for each ABCs pathogen...

  • Surveillance Evaluation

    To ensure that all cases of diseases under surveillance are being reported, audits of the reporting laboratories are performed and surveillance indicators are used...

  • ABCs Special Studies

    Special studies that require additional data collection are currently ongoing in ABCs...
