Upper respiratory tract infection (URTI)
A variety of viruses and bacteria can cause upper respiratory tract infections.
Defining most of these patient diseases is difficult because the presentations

Upper respiratory tract infections involve the nose, sinuses, pharynx, larynx, and
the large airways. COVID-19 is an infectious viral disease caused by an enveloped
