Acute upper respiratory tract infection is clinically localized above the nasal cavity and pharynx. Symptoms typically seen in such patients include nasal congestion, runny nose, sneezing, itchy throat, and coughing. The onset is usually sudden, and some patients may experience sore throats, while others may have an itchy throat. In most cases, these infections are viral. For such patients, the course of the disease is about one week and is usually self-limiting. For elderly individuals or infants and young children, who are generally more frail, it is advisable to prescribe appropriate medications for symptomatic treatment when they contract an acute upper respiratory tract infection, to prevent the aggravation of symptoms and further discomfort.
