Respiratory Infection
Overview
Respiratory infections affect the airways, throat, or lungs and are among the most common causes of cough, fever, and breathing-related symptoms. These infections may be caused by viruses, bacteria, or other organisms and can range from mild to more serious illness.
Some respiratory infections improve with rest and supportive care, while others may require medication, monitoring, or further investigation. Early assessment is important when symptoms are severe, persistent, or affecting breathing.
With proper treatment and follow-up, many respiratory infections can be managed effectively and complications reduced.
