For most infections, the immune response of the body is enough to control and apprehend the infection within a couple days, but if the tissue and the cells can't fight off the infection, the creation of pus will begin to form in the lungs which then hardens into lung abscess or suppurative pneumonitis.

Acute bronchitis, also known as a chest cold, is short-term bronchitis – inflammation of the bronchi (large and medium-sized airways) of the lungs. [2] [1] The most common symptom is a cough. [1] Other symptoms include coughing up mucus, wheezing, shortness of breath, fever, and chest discomfort. [2] The infection may last from a few to ten ...
Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. [a] Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. [8] Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. [8]
An infection of this type usually is further classified as an upper respiratory tract infection (URI or URTI) or a lower respiratory tract infection (LRI or LRTI). Lower respiratory infections, such as pneumonia, tend to be far more severe than upper respiratory infections, such as the common cold.
The infection then makes its way down to the bronchi. Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain. Bronchitis can be acute or chronic. [1] Acute bronchitis usually has a cough that lasts around three weeks, [4] and is also known as a chest cold. [5] In more than 90% of cases, the cause is a viral infection ...
A routine chest X-ray is not always necessary for people who have symptoms of a lower respiratory tract infection. [4] Influenza affects both the upper and lower respiratory tracts. [citation needed] Antibiotics are the first line treatment for pneumonia; however, they are neither effective nor indicated for parasitic or viral infections. Acute ...
Tonsillitis is swelling of the tonsils by a bacterial or viral infection. This inflammation can lead to airway obstruction. From tonsillitis can come a peritonsillar abscess which is the most common upper airway infection and occurs primarily in young adults. It causes swelling in one of the tonsils, pushing the uvula to the unaffected side. [9]
Obstructive sleep apnea (OSA) is the most common sleep-related breathing disorder and is characterized by recurrent episodes of complete or partial obstruction of the upper airway leading to reduced or absent breathing during sleep.
