Human adenoviruses (HAdV) are a major cause of acute respiratory diseases (ARD), gastroenteritis, conjunctivitis and urinary infections. Between November 2000-April 2007, total 468 nasopharyngeal aspirate samples were collected from children with ARD at the Clinics Hospital Uberlândia. These tested by immunofluorescence assay (IFA) 3% (14/468) positive for presence HAdV. By performing polymerase chain reaction (PCR) to detect HAdV DNA in that negative or inconclusive all viruses identifiable...

Human rhinoviruses (HRV) are usually associated with mild respiratory symptoms in children. However, some studies have found that HRV can cause severe disease, especially when the patient is co-infected a second virus. In this study, 532 nasopharyngeal aspirates (NPAs) were collected over nine-year period from children at Clinics Hospital of Uberlândia. The NPAs then tested for RNA using reverse transcription-polymerase chain reaction. Eighty-three specimens diagnosed lower tract illness...
