Cough due to upper respiratory tract infection (URI) or cough without preceding infection is one of the most frequent complaints encountered by family physicians and pediatric providers.1 Cough, more than other symptoms, is disruptive, prevents the sick child and the family from sleeping,2 and might result in frustration. In the absence of effective antiviral treatment for URI, parents try to f...

To determine the role of the pandemic influenza A/H1N1 2009 (A/H1N1 2009pdm) in acute respiratory tract infections (ARTIs) and its impact on the epidemic of seasonal influenza viruses and other common respiratory viruses, nasal and throat swabs taken from 7,776 patients with suspected viral ARTIs from 2006 through 2010 in Beijing, China were screened by real-time PCR for influenza virus typing ...

Influenza RNA in blood (viremia) was detected in 9 of 79 (11.4%) hematopoietic cell transplant recipients with influenza, and was less frequently observed in patients with upper respiratory tract disease only and more frequently in patients infected with 2009 pandemic influenza A/H1N1 strain (versus seasonal strains). Viremia increased the risk of progression to lower respiratory tract disease ...

background upper respiratory tract infections (urti) in children are the most frequent reasons for visiting a family doctor, commonly resulting in inappropriate prescription of antibiotics. in underdeveloped countries, a viral respiratory tract infection may be followed by serious complications. more than 200 viral species are associated with respiratory tract diseases in humans and this number...

OBJECTIVES To determine the spectrum of N and G genotypes of respiratory syncytial virus (RSV) causing respiratory tract infection and whether particular genotypes are associated with severity of infection. PATIENTS AND METHODS Nasopharyngeal aspirates (NPAs) were obtained from 114 infants with acute respiratory tract infection due to RSV over two seasons. Viral mRNA was extracted from NPAs o...

Pathogens causing significant respiratory disease in growing pigs include Porcine reproductive and respiratory syndrome virus, Porcine circovirus 2, swine influenza virus, porcine respiratory coronavirus, Mycoplasma hyopneumoniae, and Bordetella bronchiseptica. The objective of this research was to characterize the respiratory excretion of these pathogens by acutely infected pigs. Pigs were ino...
