Acute upper respiratory infections can be self-limiting in clinical settings. It is important to know that upper respiratory infections, mostly caused by viruses, account for about 70% to over 90% of cases. When an upper respiratory tract infection caused by a virus occurs, it is a self-limiting illness. Thus, when acute upper respiratory infections present symptoms such as nasal congestion, runny nose, sneezing, and even coughing or sore throat.

If the infection is caused by a virus, the patient can be completely cured. However, it is also important to drink plenty of water during this period and eat foods high in vitamins and proteins to boost the body's immune system. Patients should also be advised to avoid cold and cooling foods, as acute upper respiratory infections can generally heal on their own.
