Active Bacterial Core Surveillance (ABCs)

Well informed parent.
The Connecticut Active Bacterial Core Surveillance (ABCs) project is a collaboration between the Connecticut Department of Public Health (DPH) and the Centers for Disease Control and Prevention (CDC). The objective of this project is to determine the incidence and epidemiology of invasive disease due to group A Streptococcus, group B Streptococcus, Haemophilus influenza, Methicillin-Resistant Staphylococcus aureus (MRSA), Neisseria meningitidis, and Streptococcus pneumoniae. Some of these diseases are vaccine preventable and include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae serotype b (Hib).

Special studies for the ABCs project include enhanced surveillance for early- and late-onset (0-89 days) group B Streptococcus disease, invasive pneumococcal disease in children less than 3 months to 18 years, neonatal sepsis surveillance, and pneumococcal conjugate vaccine effectiveness evaluations in children and adults.

Information collected through the ABCs project contributed to revised CDC guidelines about universal screening of pregnant women for group B Streptococcus infections, prevention of group A Streptococcus infections among certain groups of people, and enhancement of surveillance for MRSA and drug-resistant Streptococcus pneumoniae.

 The most up-to-date information for diseases followed by the ABCs program is on the CDC’s website:
