Influenza A(H3N2) strains isolated during 2014-15 in Alachua County, Florida, USA, belonged to hemagglutinin gene clade 3C.2a. High rates of influenza-like illness and confirmed influenza cases in children were associated with a decrease in estimated vaccine effectiveness. Illnesses were milder than in 2013-14; severe cases were concentrated in elderly patients with underlying diseases.
A second trimester fetal demise followed influenza-like illness in early pregnancy. Influenza A virus (H1N1) was identified in maternal and fetal tissue, confirming transplacental passage. These findings suggested a causal relationship between early exposure and fetal demise. Management of future influenza outbreaks should include evaluation of products of conception associated with fetal loss.
BACKGROUND The transmission of influenza viruses occurs person to person and is facilitated by contacts within enclosed environments such as households. The aim of this study was to evaluate secondary attack rates and factors associated with household transmission of laboratory-confirmed influenza A(H1N1)pdm09 in the pandemic and post-pandemic seasons. METHODS During the 2009-2010 and 2010-20...
background: primary health care workers (phcw) are the front-liners in any infectious disease outbreaks. the recent outbreak of h1n1 influenza demonstrated that uptake of h1n1 vaccination remained low amongst pchw despite its proven effectiveness. this trend is worrying as phcw are the first point of contact in any emerging outbreak of future influenza epidemic. purpose: to investigate factors ...
BACKGROUND Immunocompromised patients are vulnerable to severe or complicated influenza infection. Vaccination is widely recommended for this group. This systematic review and meta-analysis assesses influenza vaccination for immunocompromised patients in terms of preventing influenza-like illness and laboratory confirmed influenza, serological response and adverse events. METHODOLOGY/PRINCIPA...
Background and Objectives: Syndromic surveillance systems are used to early detection of outbreaks. The purpose of this study was to determine the feasibility of clinical and non-clinical data sources used in influenza syndromic surveillance in Zanjan. Methods: In this time series study, clinical and non-clinical data related to influenza like illness (ILI) as a potential data source of synd...
Objective The objective was to forecast and validate prediction estimates of influenza activity in Houston, TX using four years of historical influenza-like illness (ILI) from three surveillance data capture mechanisms. Background Using novel surveillance methods and historical data to estimate future trends of influenza-like illness can lead to early detection of influenza activity increases a...
BACKGROUND Swine workers may play a key role in transmission of zoonotic influenza viruses. At the same time, little is known about the extent and effectiveness of influenza prevention programs for these at-risk workers. OBJECTIVES To characterize practices and attitudes regarding zoonotic influenza transmission among swine workers in Romania. METHODS We conducted a convenience survey of sw...
BACKGROUND Estimating the economic impact of influenza is complicated because the disease may have non-specific symptoms, and many patients with influenza are registered with other diagnoses. Furthermore, in some countries like Norway, employees can be on paid sick leave for a specified number of days without a doctor's certificate ("self-reported sick leave") and these sick leaves are not regi...
