The purpose of this study was to compare the 2005- 2006 and 2006-2007 Influenza seasons using Influenza-like illness (ILI) data received from Emergency Departments in Miami-Dade County.

A retrospective chart review was performed to examine chief complaint, syndrome classification and discharge diagnoses of laboratory confirmed Salmonella Enteritidis phage type (PT) 13 cases who visited the Emergency Departments (ED) of two local hospitals during a province-wide outbreak in Ontario in the fall of 2005. This assessment was used to assess the sensitivity of the ED syn-dromic surveillance system to detect a local foodborne outbreak, and to modify syndrome classification.

In some influenza seasons, morbidity and mortality closely follow the expected seasonal variation. In these years, approaches such as Serflingís model and seasonal-based syndromic outbreak detectors, in use in EARS, work well. In other years, though, short but intense variations occur in addition to the longer term seasonal variation. These intense outbreaks, which are often multimodal, have important implications for both syndromic surveillance and influenza epidemiology. Unfortunately, they are both difficult to characterize and poorly understood. In this paper, we apply techniques from time-frequency distribution theory to identify the temporal location, duration, and amplitude of intense outbreaks occurring in the presence of longer time scale variations.

Epidemiologists, public health agencies and scientists increasingly augment traditional surveillance systems with alternative data sources such as, digital surveillance systems utilizing news reports and social media, over-the-counter medication sales, and school absenteeism. Similar to school absenteeism, an increase in reservation cancellations could serve as an early indicator of social disruption including a major public health event. In this study, we evaluated whether a rise in restaurant table availabilities could be associated with an increase in disease incidence.

 

Objective

The objective of this study is to evaluate whether trends in online restaurant table reservations can be used as an early indicator for a disease outbreak.

Research has shown that Canadian First Nation (FN) populations were disproportionately affected by the 2009 H1N1 influenza pan- demic. However, the mechanisms for the disproportionate outcomes are not well understood. Possibilities such as healthcare access, in- frastructure and housing issues, and pre-existing comorbidities have been suggested. We estimated the odds of hospitalization and inten- sive care unit admission for cases of H1N1 influenza among FN liv- ing in Manitoba, Canada, to determine the effect of location of residency and other factors on disease outcomes during the 2009 H1N1 pandemic.

Objective

We sought to measure from surveillance data the effect of prox- imity to an urban centre (rurality) and other risk factors, (e.g., age, residency on a FN reservation, and pandemic wave) on hospitaliza- tion and intensive care unit admission for severe influenza.
