Viruses causing upper respiratory infections

"Viruses causing upper respiratory infections" refers to a large and diverse group of viruses (not a single molecule or receptor) that infect the mucosa of the upper respiratory tract, causing acute illnesses such as the common cold, pharyngitis, sinusitis, and laryngitis. The most prevalent agents include rhinoviruses (responsible for up to 80% of common colds), human coronaviruses (excluding SARS/MERS), influenza viruses (possible upper/lower involvement), parainfluenza viruses, adenoviruses, respiratory syncytial virus (RSV), enteroviruses, human metapneumovirus, and bocavirus[1][4][5][6][7]. There is no unifying receptor or molecular target for this group; each virus has distinct entry mechanisms, replication cycles, and epidemiological behaviors. Most infections are self-limiting, but complications and more severe illnesses are common in specific populations. Pharmacological interventions are limited to specific subtypes (e.g., influenza antivirals, RSV monoclonal antibodies), and the inappropriate use of antibiotics remains a significant public health concern[2][7].
