LP18337-3   Parainfluenza virus
Parainfluenza virus is from the family Paramyxoviridae and the genera Paramyxovirus which includes the parainfluenza viruses and the mumps virus. Paramyxoviruses are particles up to 300 nm in diameter. They are spiral, tube-like symmetrical nucleocapsids which contain a monopartite, single-stranded, negative-sense RNA genome and an RNA-directed RNA polymerase. There is a matrix protein at the base of a double-layered lipid envelope which contains spikes with two glycoproteins, a viral attachment protein and a fusion protein. The viral protein spikes in parainfluenza viruses have hemagglutinating and neuraminidase activities. As all paramyxoviruses are labile, they are quickly inactivated (e.g., by heat, detergents, ultraviolet light). Primary infections occur in young children and cause mild or severe upper and lower respiratory tract infections. Reinfection is common and results in milder manifestation. Transmission is by direct contact or by droplets. Parainfluenza virus diseases are usually endemic although they can be epidemic. [NCBI Books:NBK8461] Source: Regenstrief LOINC
