Traveling Epidemic Waves in Biosurveillance Data: Identifying Early Hotspots of Respiratory Illness
Content Type: Abstract
We have previously shown that timeliness of detection is influenced both by the data source (e.g., ambulatory vs. emergency department) and demographic characteristics of patient populations (e.g., age). Because epidemic waves are thought to… read more… may affect disease susceptibility and hence timing of visits. Here, we describe spatial models of local … may affect disease susceptibility and hence timing of visits. Here, we describe spatial models of local … referral bias by including the likelihood of a hospital visit based on the market share of a zip code. The model … -
State Surveillance Data Improves a Clinical Prediction Model for Pertussis
Content Type: Abstract
Bordetella Pertussis outbreaks cause morbidity in all age groups, but the infection is most dangerous for young infants. Pertussis is difficult to diagnose, especially in its early stages, and definitive test results are not… read more… and negative predictive value (PPV, NPV), and area un- der the ROC curve (AROC)).

Evaluation of Online Media Reports for Global Infectious Disease Intelligence
Content Type: Abstract
While traditional means of surveillance by governments, multi-national agencies, and institutional networks assist in reporting and confirming infectious disease outbreaks, these formal sources of information are limited by their… read more… to only 24 released by WHO and 623 found on the ProMED mail system.

Improving Detection Timeliness by Modeling and Correcting for Data Availability Delays
Content Type: Abstract
The performance of even the most advanced syndromic surveillance systems can be undermined if the monitored data is delayed before it arrives into the system. In such cases, an outbreak may be detected only after it is too late for appropriate… read more… 2005. These models predict the percentage of total visits from a given date that will be available to the …
