Respiratory Infections

Respiratory infections are infectious diseases of the respiratory tract that are mostly caused by bacteria and viruses. They cause infections of the throat, sinuses, airway path, and lungs. Respiratory infections are typically divided into two types: upper tract respiratory infection and lower tract respiratory infection.
