Respiratory infections are diseases that affect the respiratory tract, which includes the nose, throat, bronchi, and lungs. These infections can be caused by various microorganisms, including viruses, bacteria, and, in some cases, fungi. They are common at all ages and can range from mild to severe, depending on the type of infection and the individual's health status.
Patients often ask about the signs and symptoms of a respiratory infection, which can include cough, fever, shortness of breath, nasal congestion, sore throat, and fatigue.
A common question is how these infections are diagnosed. Diagnosis is usually based on symptoms, a physical examination, and, in some cases, laboratory tests such as blood tests, throat cultures, or chest imaging (X-rays).
Patients want to know when they should consult a doctor. It is recommended to seek medical attention if symptoms are severe, if fever lasts more than a few days, if there is difficulty breathing, or if the cough does not improve within a week.
Another common question is about the treatments available. Treatments vary depending on the type of infection (viral or bacterial) but may include antibiotics (for bacterial infections), medications to relieve symptoms, rest, and staying well hydrated.
