The genus Orthopneumovirus consists of pathogens that target the upper respiratory tract within their specific hosts.

Orthopneumoviruses can cause diseases that range from a less-severe upper-respiratory illness to severe bronchiolitis or pneumonia.

Orthopneumoviruses are found specifically in the members of the species Homo sapiens, Ovis aries, Capra aegagrus hircus, Bos primigenius, and the order Rodentia.

[4] Having a weak immune system and pre-existing conditions such as asthma can be leading factors in catching an orthopneumovirus.

Molecular studies have been on the rise due to continuing materials and information obtained regarding recombinant DNA arrangements that might offer a foundation for vaccine development.

RSV is the leading viral agent among pneumoviruses in pediatric upper respiratory diseases globally.
