Understanding Upper Respiratory Infections

Upper respiratory infections, commonly known as the cold, are usually caused by viral agents such as rhinovirus or coronaviruses. These infections are generally self-limiting, meaning they resolve on their own without the need for antibiotics, which are ineffective against viruses. During clinical assessments, the hallmark symptoms of a viral upper respiratory infection include nasal congestion, cough, and sore throat, and it is significant to recognize that the course of symptoms typically lasts about five to seven days. Attention should also be paid to differentiating between benign cold symptoms and more severe infections, such as influenza or COVID-19, which may present atypically.
