Abstract: |
Respiratory syncytial virus (RSV) and human metapneumovirus (HMPV) are recognized as the most serious causes of severe acute lower respiratory tract illnesses in young children and infants. Rapid and accurate detection and characterization of RSV is important in the clinical management of individual patients because of the availability of specific antiviral drugs. Early detection of RSV and HMPV infections is also necessary for cohorting of infected patients to prevent nosocomial spread. Tube and shell viral cultures remain the gold standard for RSV and HMPV detection, but they are time consuming and require attention to transport and prompt inoculation. Quite a few of rapid viral antigen tests are commercially available, which yield results within 1 hour after specimen collection. However, their sensitivity is limited and negative results usually require a more sensitive back-up test such as a molecular assay or culture. With the increased number of multiplexed molecular Food and Drug Administration (FDA)-approved assays, simultaneous detection and identification of common viral pathogens is becoming the main tool for detection and identification of RSV and MPHV. © 2015 by ASM Press. |
