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). Source and secondary … -
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 … -
Predictors of vaccination uptake for the 2009 influenza pandemic (H1N1) in Montreal
Content Type: Abstract
Work on vaccination timing and promotion largely precedes the 2009 pandemic. Post-pandemic studies examining the wide range of local vaccination efforts mostly have been limited to surveys assessing the role of administrative strategies, logistical… read more… for the 2009 influenza pandemic (H1N1) in Montréal Luc de Montigny*, Aman Verma, Katia Charland and David … with the lowest uptake, the Health Department’s campaign did not appear to increase vaccination, reflecting … permitting all non-commercial use, distribution, and reproduction in … -
Quantifying the potential benefit of early detection for preventing morbidity and mortality: a simulation study of cryptosporidium outbreak
Content Type: Abstract
Many studies evaluate the timeliness and accuracy of outbreak detection algorithms used in syndromic surveillance. Of greater interest, however, is defining the outcome associated with improved detection. In case of a waterborne cryptosporidiosis… read more… University, Montréal, Canada; 2École Polytechnique de Montréal, Montréal, Canada; and 3Direction de Santé Publique de Montréal, Montréal, Canada E-mail: … outbreak with a 72-hour treatment plant failure.
