Question: can sinus infection cause upper respiratory infection?
Answer: Your upper respiratory tract includes the nose, throat, pharynx, larynx, and bronchi. Without a doubt, the common cold is the most well-known URI. Other types of URIs include sinusitis, pharyngitis, epiglottitis, and tracheobronchitis. Influenza, on the other hand, isn't an URI because it's a systemic illness.
