conclusions: this study indicates that rsv is a substantial cause of respiratory tract infection in infants less than 2 years old. rt-pcr offers a rapid method for detection of rsv in hospitalized children with lrti. results: during the study period, 9 children had a positive result for rsv infection. the median age of these patients was 10 months. bronchiolitis was the clinical diagnosis of pa...

The following principles of appropriate antibiotic use for adults with nonspecific upper respiratory tract infections apply to immunocompetent adults without complicating comorbid conditions, such as chronic lung or heart disease. 1. The diagnosis of nonspecific upper respiratory tract infection or acute rhinopharyngitis should be used to denote an acute infection that is typically viral in ori...

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...

Copyright © 2008 Massachusetts Medical Society. A cute lower respiratory tract infections are a persistent and pervasive public health problem. They cause a greater burden of disease worldwide than human immunodeficiency virus infection, malaria, cancer, or heart attacks.1 In the United States, they cause more disease and death than any other infection, and there has been little change in morta...

background: both influenza a virus (iav) and respiratory syncytial virus (rsv) cause acute respiratory infection (ari) in infants and young children. this study was conducted to determine influenza a virus and its co infection with rsv among the hospitalized children with ari. methods: a total of 153 throat samples of the hospitalized young children aged between below one year and 5 years with ...

Introduction Chlamydia pneumoniae was initially recognized as a cause of acute lower respiratory tract infections such as pneumonia and bronchitis in both adults and children (1-7), hence the species name “pneumoniae.” Moreover, C. pneumoniae was noted in some individuals to cause a persistent respiratory tract infection following an acute infection (8), which is entirely consistent with the kn...

results among the 158 children evaluated in this study, 49 individuals (31.1%) had rsv infection while nine individuals (5.7%) had hmpv infection. five (55.5%) of the hmpv-infected children were male while four (44.5%) were female and 27 (55.2%) of the rsv-infected patients were females and 22 (44.8%) were males. the rsv infections were detected in mainly < one year old children and hmpv infect...

Background: Human parvovirus B19 was known as one of the possible cause of mild respiratory tract diseases in previous studies. However, there are some reports of acute obstructive respiratory disease and severe pneumonia. The purpose of current study was to assess the prevalence and clinical features of parvovirus B19 in respiratory infection. &nbsp;&nbsp; Methods: This study was conducted on...

Respiratory viruses can cause a wide spectrum of pulmonary diseases, ranging from mild, upper respiratory tract infections to severe and life-threatening lower respiratory tract infections, including the development of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). Viral clearance and subsequent recovery from infection require activation of an effective host immune resp...
