Part Description

LP248181-2   Influenza virus A & B & Respiratory syncytial virus RNA panel
Influenza viruses A and B are single-stranded RNA enveloped viruses belonging to the Orthomyxoviridae family. The symptoms of infection of Influenza A and B include fever, cough, sore throat, rhinorrhea, nasal congestion, headache, myalgia and malaise. Some patients may experience gastrointestinal symptoms including watery diarrhea, vomiting and abdominal pain. The influenza viruses spread rapidly in enclosed spaces with a documented rate of infection of 70% following a common source of exposure. Infection occurs in the respiratory epithelium in both the upper and lower respiratory tract, and the virus can be found in many specimen types, including nasal aspirates, nasal or nasopharyngeal swabs, throat swabs, sputum and tracheal aspirates. When infection rates reach epidemic proportions, hospitalization of children and elderly patients rises as does the mortality rates of elderly patients. The respiratory syncytial virus (RSV) is a member of the Paramyxoviridae family and is an enveloped pleomorphic virus. RSV is spread through contact with respiratory droplets, contact with the patient and contact with contaminated surfaces. The rate of transmission is affected by outside temperature, humidity and precipitation. RSV infection spreads faster when the temperature is low and the humidity is high in temperate zones and when rainfall levels are high in tropical climates. RSV causes severe lower respiratory infections in infants and young children. Symptoms of RSV infection include cough, low-grade fever and rhinorrhea. High risk adult populations including patients in residential facilities, those with heart and lung diseases and immunocompromised patients are susceptible to severe RSV infection and significant morbidity.(Manual of Clinical Microbiology, 11th edition, James H.
