Which family does the Newcastle disease virus belong to?

Explanation:
Classifying Newcastle disease virus hinges on its genome type and envelope. It is an enveloped, nonsegmented, negative-sense RNA virus in the family Paramyxoviridae, specifically within the genus Avulavirus. This group includes other well-known pathogens like measles, mumps, and parainfluenza viruses and is characterized by shared replication in the cytoplasm and surface fusion (F) and attachment proteins such as HN. The other families differ in genome composition and structure: Herpesviridae are double-stranded DNA viruses with different replication features; Orthomyxoviridae have segmented negative-sense RNA genomes; Reoviridae have double-stranded RNA genomes and are nonenveloped. Therefore, Newcastle disease virus belongs to Paramyxoviridae.
