Population-based Surveillance for Hepatitis C Virus, United States, 2006–2007
Surveillance for hepatitis C virus infection in 6 US sites identified 20,285 newly reported cases in 12 months (report rate 69 cases/100,000 population, range 25–108/100,000). Staff reviewed 4 laboratory reports per new case. Local surveillance data can document the effects of disease, support linkage to care, and help prevent secondary transmission

Establishment of a Statewide Network for Carbapenem-Resistant Enterobacteriaceae Prevention in a Low-Incidence Region
OBJECTIVE: To establish a statewide network to detect, control, and prevent the spread of carbapenem-resistant Enterobacteriaceae (CRE)
in a region with a low incidence of CRE infection.
DESIGN: Implementation of the Drug Resistant Organism Prevention and Coordinated Regional Epidemiology (DROP-CRE) Network.
SETTING AND PARTICIPANTS: Oregon infection prevention and microbiology laboratory personnel, including 48 microbiology laboratories,
62 acute care facilities, and 140 long-term care facilities.
METHODS: The DROP-CRE working group, comprising representatives from academic institutions and public health, convened an
interdisciplinary advisory committee to assist with planning and implementation of CRE epidemiology and control efforts. The working
group established a statewide CRE definition and surveillance plan; increased the state laboratory capacity to perform the modified Hodge
test and polymerase chain reaction for carbapenemases in real time; and administered surveys that assessed the needs and capabilities of
Oregon infection prevention and laboratory personnel. Results of these inquiries informed CRE education and the response plan.
RESULTS: Of 60 CRE reported from November 2010 through April 2013, only 3 were identified as carbapenemase producers; the cases
were not linked, and no secondary transmission was found. Microbiology laboratories, acute care facilities, and long-term care facilities
reported lacking carbapenemase testing capability, reliable interfacility communication, and CRE awareness, respectively. Survey findings
informed the creation of the Oregon CRE Toolkit, a state-specific CRE guide booklet.
CONCLUSIONS: A regional epidemiology surveillance and response network has been implemented in Oregon in advance of widespread
CRE transmission. Prospective surveillance will determine whether this collaborative approach will be successful at forestalling the emergence
of this important healthcare-associated pathogen.This is the publisher’s final pdf.

Multistate analysis of prospective Legionnaires' disease cluster detection using SaTScan, 2011-2015.
Detection of clusters of Legionnaires' disease, a leading waterborne cause of pneumonia, is challenging. Clusters vary in size and scope, are associated with a diverse range of aerosol-producing devices, including exposures such as whirlpool spas and hotel water systems typically associated with travel, and can occur without an easily identified exposure source. Recently, jurisdictions have begun to use SaTScan spatio-temporal analysis software prospectively as part of routine cluster surveillance. We used data collected by the Active Bacterial Core surveillance platform to assess the ability of SaTScan to detect Legionnaires' disease clusters. We found that SaTScan analysis using traditional surveillance data and geocoded residential addresses was unable to detect many common Legionnaires' disease cluster types, such as those associated with travel or a prolonged time between cases. Additionally, signals from an analysis designed to simulate a real-time search for clusters did not align with clusters identified by traditional surveillance methods or a retrospective SaTScan analysis. A geospatial analysis platform better tailored to the unique characteristics of Legionnaires' disease epidemiology would improve cluster detection and decrease time to public health action
