Aiding the practice of tuberculosis control: a decision support model to predict transmission
Content Type: Abstract
A new TB case can be classified as: 1) a source case for transmission leading to other, secondary active TB cases; 2) a secondary case, resulting from recent transmission; or 3) an isolated case, uninvolved in recent transmission (i.e. neither… read more… 3) an isolated case, uninvolved in recent transmission (i.e. neither source nor recipient). Source and secondary cases require more intense intervention due to their involvement in a chain of transmission; thus, … (3) an isolated case, uninvolved in recent transmission (i.e., neither source nor recipient).

The Utility of Space-Time Surveillance for Tuberculosis
Content Type: Abstract
Tuberculosis (TB) has reemerged as a global health epidemic in recent years. Although several researchers have examined the use of space-time surveillance to detect TB clusters, they have not used genetic information to… read more… genetic information to verify that detected clusters are due to person-to-person transmission. Using genetic … we sought to determine whether detected clusters were due to recent transmission. Objective This paper describes … spacetime surveillance to detect genetic clusters of TB due to person-to-person spread. Document … -

Estimating spatial patterning of dietary behaviors using grocery transaction data
Content Type: Abstract
Unhealthy diet is becoming the most important preventable cause of chronic disease burden. Dietary patterns vary across neighborhoods as a function of policy, marketing, social support, economy, and the commercial food environment.

A Probabilistic Case-finding Algorithm for Chronic Disease Surveillance
Content Type: Abstract
There is a clear need for improved surveillance of chronic diseases to guide public health practice and policy. Chronic disease surveillance has tended to use administrative data, due to the need to link encounters for an individual over time and to… read more… surveillance has tended to use administrative data, due to the need to link encounters for an individual over time and to have complete capture of all encounters. Case-detection algorithms generally combine … variables found in the data using Boolean operators (i.e., AND, OR, NOT). For example, a commonly used algorithm … -
