An Exploration of the H1N1 Outbreak in Champaign and Urbana Elementary Schools

Champaign and Urbana, Illinois are considered twin cities that share the University of Illinois. Due to different geographic recruitment procedures, Champaign and Urbana public elementary schools offer a particularly novel opportunity to examine the H1N1 outbreak among students. Urbana schools recruit from specific geographic areas (neighborhoods) designated by the school district whereas Champaign schools are non-selective in their composition where students residing in Champaign can attend any school within the city.

Transmission Dynamics of Seasonal Influenza in Abidjan: Epidemiology and Modeling

Influenza poses a global health threat. The disease affects all ages, often with variable clinical features.

Unplanned School Closures in the United States: Evaluation of Economic and Social Costs and Consequences for Students’ Families

The Centers for Disease Control and Prevention (CDC) recommends implementing early targeted school closures as one of the front-line interventions to slow progression of a severe influenza pandemic before appropriate vaccine becomes available. However, prolonged school closures may impose unintended economic and social costs and consequences to students’ families. These costs and consequences have not been carefully evaluated.

Comparison of ILINet and ESSENCE for Influenza Surveillance at the Local Level

ILINet is used nationwide by sentinel healthcare providers for reporting weekly outpatient visit numbers for influenza-like illness to CDC. The Florida Department of Health receives urgent care center (UCC) data through ESSENCE from participating facilities. Seminole County is unique in that its four sentinel providers located in separate UCCs report into both systems, and all their discharge diagnoses are available through ESSENCE.

Monitoring Emergent Avian Influenza Viruses Subtypes H5 and H7 in Wild Birds in Ukraine

To date, avian influenza virus (AIV) is an unpredictable pathogen affecting both animals, birds and people. The regular emergence of new strains and variants with different properties and pathogenicities requires additional monitoring and careful research of those viruses. It is known that wild birds— especially waterfowl and shorebirds— are the main and primary reservoir of AIV in nature which makes epizootological monitoring of populations of these birds necessary.

Documenting the Missed Opportunity Period for Influenza Vaccination in Office-based Settings

Missed opportunities for influenza vaccination in office-based settings occur when patients (who are inclined to accept influenza vaccination if a provider recommends it) remain unvaccinated after a fall/winter healthcare visit. Healthcare providers can be very influential in encouraging patients to obtain influenza vaccination, but little is known in real-time during annual campaigns of how many and what type of providers are actually giving vaccinations in office settings.

Wikipedia Usage Estimates Prevalence of Influenza-like Illness in Near Real-Time

The purpose of this work was to develop a novel method of estimating the amount of influenza-like illness (ILI) in a population, in near-real time, by using a source of information that is completely open to the public and free to access. We investigated the usefulness of data gathered from Wikipedia to estimate the prevalence of ILI in the United States, using data from the Centers for Disease Control and Prevention (CDC) as well as Google Flu Trends.

Ebola, Enterovirus, MERS, Novel Flu, and other Challenges for Public Health Surveillance Practitioners

Public health practitioners endeavor to expand and refine their syndromic and other advanced surveillance systems that are designed to supplement their existing laboratory testing and disease surveillance toolkit. While much of the development and widespread implementation of these systems had been supported by public health preparedness funding, the reduction of these monies has greatly constrained the ability of public health agencies to staff and maintain these systems.

Ratio of Excess ED ILI Visits to Seroprevalence, Influenza A/H1N1 Infection, FL, 2009

A seroprevalence survey carried out in four counties in the Tampa Bay area of Florida (Hillsborough, Pinellas, Manatee and Pasco) provided an estimate of cumulative incidence of infection due to the 2009 influenza A (H1N1) as of the end of that year’s pandemic. During the pandemic, high-level decison-makers wanted timely, credible forecasts as to the likely near-term course of the pandemic.

Real-time Laboratory-Based Influenza Surveillance with Xpert Flu

Previous studies have demonstrated the benefit of laboratory surveillance and its capability to accurately detect influenza outbreaks earlier than syndromic surveillance. Current laboratory surveillance has an approximate 2-week lag due to laboratory test turn–around time and data collection. In order to provide real-time access to aggregated test results, we utilized direct cloud connectivity with a rapid PCR-based influenza test, Xpert Flu, to centrally consolidate test results along with GIS data.
