Disease Control and Environmental Epidemiology Division

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 CDPHE Emerging Infections Program staff complete the IPD case report in 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 area, local 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 Surveillance (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. 

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, CDPHE has developed a notification letter (Pneumococcal Exposure Letter) to inform parents of childcare attendees if necessary. 

 General Information:

• ABCs case report form

• Pneumococcal exposure letter

• Childcare immunization requirements

 Other Resources:

• Pneumococcal Disease chapter of the CDC Epidemiology and Prevention of Vaccine-Preventable Diseases (Pink Book)

• Pneumococcal Disease chapter of the CDC Manual for the Surveillance of Vaccine-Preventable Diseases

Statistics:

• Emerging Infections Program Surveillance Reports

• Surveillance Reports for Communicable Diseases
