What are the different types of respiratory infections?

The

respiratory system consists of both lower and upper respiratory system. The lower part consists of bronchial tubes and lungs, while the upper part consists of mouth, neck, nose and cavities. The respiratory system infections can affect both areas and are generally caused by bacteria or viruses. It is not uncommon for the lower respiratory infection to occur after or as a complication that infects the upper respiratory tract.

Upper respiratory tract infections are more common and usually less serous than infections in the lower system. Most lower airway infections are caused by bacteria, while the injection in the upper travels of the respiratory is caused by viruses. However, there are several bacterial diseases that can affect the upper respiratory tract. The lower respiratory infection also causes a person to have difficulty breathing and can experience shortness of breath or wheezing. The upper respiratory system infections cause symptoms such as cough, face pressure and blocked nasal passages, either with or without cold. Fever may also be a breakOmna when the upper respiratory system is infected.

Common infections of the upper respiratory system include flu and cold. Colds can cause a person to feel uncomfortable, but they are usually not a serious health threat and tend to be cleaned themselves without having to see a doctor. The influenza may represent serious symptoms and may develop into a health threat, especially in people with a vulnerable immune system such as very old or very young. Both of these conditions are viral infections that do not respond to the treatment of antibiotics.

Bronchitis and pneumonia are the most common types of lower respiratory system infections, especially in people who have existing lung diseases, smoke or smoke. Many cases of these infections are caused by bacteria and therefore antibiotics can be treated, but there are also viral trunks of both diseases. Lower airway infections can causeSignificant health problems and a person showing the symptoms of these diseases should seek medical treatment from a doctor.
