Traditional surveillance for respiratory viruses relies on symptom detection and laboratory detection during medically attended encounters for acute respiratory infection/influenza-like illness (ARI/ILI). Ecological momentary reporting using text messages is a novel method for surveillance. This study compares respiratory viral activity detected through longitudinal community-based surveillance...

Respiratory virus infections are a major health concern and represent the primary cause of testing consultation and hospitalization for young children. We developed and compared two assays that allow the detection of up to 23 different respiratory viruses that frequently infect children. The first method consisted of single TaqMan quantitative real-time PCR assays in a 96-well-plate format. The...

BACKGROUND As the threat of zoonoses and the emergence of pandemic-prone respiratory viruses increases, there is a need to establish baseline information on the incidence of endemic pathogens in countries worldwide. OBJECTIVES To investigate the presence of viruses associated with influenza-like illnesses (ILI) in Uganda. METHODS A cross-sectional study was conducted in which nasopharyngeal...

OBJECTIVE Detection of the eight most common respiratory viruses: human respiratory syncytial virus (HRSV), influenza virus A and B (IA and IB), parainfluenza viruses 1, 2 and 3 (HPIV1, 2 and 3), adenovirus (Ad) and human metapneumovirus (HMPV), in order to establish the etiology of acute respiratory infections (ARIs) and the epidemiology of these viruses in young children seen at Hospital Univ...

BACKGROUND In 2010, the Tennessee Department of Health, in collaboration with the Centers for Disease Control and Prevention (CDC), expanded influenza surveillance in Tennessee to include other respiratory viruses. OBJECTIVES To determine the prevalence and seasonality of influenza and other respiratory viruses during the influenza seasons of 2010-2012. METHODS Nasal and nasopharangeal swab...

backgrounds and objectives: classified as low pathogenic avian influenza (lpai) viruses, the h9n2 subtype causes severe respiratory disease in poultry farms and occasional respiratory disease in humans. in this study, the neuraminidase (na) gene of three avian influenza (ai) h9n2 strains isolated from poultry farms in iran during 2010-11, as well as other reported iranian h9n2 isolates, were ge...

Viruses are the major contributors to the morbidity and mortality of upper and lower acute respiratory infections (ARIs) for all age groups. The aim of this study was to determine the frequencies for a large range of respiratory viruses using a sensitive molecular detection technique in specimens from outpatients of all ages with ARIs. Nasopharyngeal aspirates were obtained from 162 individuals...

The frequency of viral pathogens causing respiratory infections in children in the cities of Rio de Janeiro and Teresópolis was investigated. Nasal swabs from children with acute respiratory illnesses were collected between March 2006 and October 2007. Specimens were tested for viral detection by conventional (RT)-PCR and/or real time PCR. Of the 205 nasal swabs tested, 64 (31.2%) were positive...
