INTRODUCTION Haemagglutination-inhibition (HI) antibody titer is a correlate of protection against influenza; its persistence after infection or vaccination is important to determining susceptibility to subsequent infection. Few studies, however, have reported longitudinal data regarding the magnitude and duration of HI protection following natural seasonal influenza A infection. METHODS Usin...

Methods The data elements that were included in this study were: daily emergency department (ED) ILI rate, 7 day moving average ED ILI rate, zip code, and date from October 1, 2013 to March 31, 2014. The data region was the catchment area of an urban academic medical center (AMC). The data were processed using the GUARDIAN (Geographic Utilization of Artificial Intelligence in Real-Time for Dise...

This paper describes the multilingual design of the EuroWordNet database. The EuroWordNet database stores wordnets as autonomous language-specific structures that are interconnected via an Inter-Lingual-Index (ILI). In this paper, we discuss the possibilities to create mappings from each wordnet to the central ILI and how the ILI itself can be adapted to provide more overlap across the wordnets...

In Brief This article reports on an investigation of whether an intensive lifestyle intervention (ILI) would reduce gastrointestinal symptoms over 4 years of follow-up for participants in the Action for Health in Diabetes (Look AHEAD) trial compared to a diabetes support and education (DSE) group. Look AHEAD is a randomized, multicenter trial comparing overweight and obese adults with type 2 di...

The CDC presented considerations for distinguishing influenza-like illness from inhalational anthrax (MMWR, 9 Nov 01, 50:44 pp. 984-986). “Although many different illness might present with influenza-like illnesses (ILI) symptoms, the presence of certain signs and symptoms might help to distinguish other causes of ILI from inhalational anthrax. Nasal congestion and rhinorrhea are features of mo...

Circulating levels of both seasonal and pandemic influenza require constant surveillance to ensure the health and safety of the population. While up-to-date information is critical, traditional surveillance systems can have data availability lags of up to two weeks. We introduce a novel method of estimating, in near-real time, the level of influenza-like illness (ILI) in the United States (US) ...

OBJECTIVES We aim to estimate the prevalence of influenza-like illness (ILI) by occupation and to identify occupations associated with increased ILI prevalence. METHODS Between September 2009 and August 2010, the Centers for Disease Control (CDC) included questions on ILI symptoms on the Behavioral Risk Factor Surveillance System (BRFSS). Washington State collects the occupation of all employ...

BACKGROUND Most influenza surveillance is based on data from urban sentinel hospitals; little is known about influenza activity in rural communities. We conducted influenza surveillance in a rural region of China with the aim of detecting influenza activity in the 2009/2010 influenza season. METHODS The study was conducted from October 2009 to March 2010. Real-time polymerase chain reaction w...

OBJECTIVE To assess the effects of winter/summer school breaks on occurrences of influenza-like illness (ILI). METHODS We jointly analysed ILI surveillance data with the timing of school breaks in a temperate district in Beijing, China from 2008 to 2015. ILI incidence rate ratios (IRRs) of schoolchildren (5-14 and 15-24 years of age) to adults (25-59 and >60 years of age) were used to measure...

Background.  School closures are an important mitigation strategy during influenza pandemic: if implemented early in a local outbreak, they can slow the disease spread in the surrounding community. During seasonal influenza epidemics, school closures may occur reactively, after the disease is already widespread in the community. Such reactive closures are often too late to reduce influenza tran...
