Alaska Invasive Bacterial Disease Surveillance Report Streptococcus pneumoniae – 2015
AIP has conducted statewide surveillance of invasive Streptococcus pneumoniae since 1986. Beginning in January 2007, invasive S. pneumoniae became a reportable condition to the State of Alaska Division of Public Health (DPH). Reports of cases of disease caused by this organism are shared between AIP and DPH.
The population of the State of Alaska in 2015 was 737,625; 144,274 (19%) were Alaska Native people. Source: AK Dept. of Labor & Workforce Development population estimates.
An isolate of Streptococcus pneumoniae from a normally sterile site that has been taken from a resident of Alaska.
Participating laboratories send isolates recovered from sterile sites to the AIP laboratory in Anchorage; materials and forms for isolate shipment and data collection are provided to each laboratory by AIP. Demographic and clinical information on the cases are collected from a review of medical records. Annually, AIP asks that each laboratory review their records and provide information on any cases that may have been overlooked.
