Pneumococcal Disease Investigation

Investigating Cases of Invasive Pneumococcal Disease (IPD)

Although disease control measures are not routinely required for reported cases of invasive pneumococcal disease (IPD), some follow-up for the purpose of collecting relevant epidemiologic information is needed for cases < 5 years of age.


Within the 5-county Denver Metropolitan area (Adams, Arapahoe, Denver, Douglas, and Jefferson Counties), the Colorado Department of Public Health and Environment Emerging Infections Program (EIP) staff complete the IPD case report in the Colorado Electronic Disease Reporting System (CEDRS) for cases of all ages through medical chart review. Local health departments in EIP counties do not need to follow-up on IPD reports.


Outside the 5-county Denver Metropolitan arealocal public health agencies should follow-up on reported IPD cases in children < 5 years of age by completing the following CEDRS fields:


  • Demographics

  • Case information

  • Lab/medical testing

  • Extended record: Sections in red text only, including the vaccine history section


If helpful, the “Active Bacterial Core Monitoring (ABCs) Case Report Form” may be used to gather the above information regarding IPD cases. The following sections of the ABCs form correspond to the required fields in CEDRS: Sections 1, 2, 4a, 4b, 5, 8, 9a, 9b, 10,11a, 11b, 17, 18a, 19, 20, and 27.


Be sure to record the pneumococcal vaccine date, name, manufacturer, and lot number. 


The information from the ABCs case report form should then be entered in CEDRS.   


Pneumococcal Disease in Childcare Facilities:

A case of invasive pneumococcal disease in a childcare facility often causes concern among parents.  Though no contact investigation is needed, the department has developed a notification letter to inform parents of childcare attendees if necessary.
