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.

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.

A Systematic Review of Influenza Forecasting Studies

Researchers have developed varied methods for forecasting influenza activity using surveillance data with predictive models, but real-world applications in public health programs are rare. To inform consideration of whether and how public health practice should incorporate influenza forecasting, we conducted a systematic review of these methods.


To assess studies of epidemiological forecasting models for human influenza activity.

Effect of 4-Day School District Closure on Influenza-Like Illness Rates Among Students and Household Members — Kentucky, 2013

Coordinated proactive school closures can help to reduce disease transmission in communities during an influenza pandemic; however, limited information is available about effects of school closures during influenza-like illness (ILI) outbreaks. A rural school district (District A) in Kentucky was closed during January 29-February 1, 2013, in response to an increase in ILI-related student absenteeism.

Electronic School Absenteeism System for Multiple Disease Surveillance in Hong Kong

Surveillance systems utilizing early indicator of disease activity would be useful for monitoring community disease pattern and facilitating timely decision making on public health interventions in an evidence-based manner. School absenteeism has been previously considered as a possible syndromic approach for monitoring influenza activity.

Enhancing Respiratory Infection Surveillance on the US/Mexico Border- Arizona BIDS Program Sentinel Surveillance Data

This project was established through the Border Infectious Disease Surveillance (BIDS) program in Arizona (AZ) to monitor infecting respiratory pathogens among hospitalized patients with Severe Acute Respiratory Infections (SARI) in the AZ border region from September 2010 to the present.


To present the epidemiology, clinical aspects, and laboratory results of AZ SARI case patients and to describe respiratory viruses in the AZ border region.

The Evolution of the WHO/NREVSS Influenza Surveillance System: The Challenges and Opportunities that Accompany Electronic Laboratory Data

The Influenza Division (ID) in the Centers for Disease Control and Prevention (CDC) maintains the WHO/NREVSS surveillance system, a network of laboratories in the U.S. that report influenza testing results. This system has seen many changes during the past 40 years, especially since the 2009 H1N1 pandemic. This was due in large part to increased adoption of HL7 messaging via PHLIP. PHLIP data is detailed, standardized influenza testing information, reported in near real-time.
