Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. [3] [14] Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. [15]
Habit cough is commonly characterized by a harsh barking cough, and can persist for weeks, months, and even years. The cough's hallmarks are severe frequency, sometimes a cough every 2–3 seconds, and the lack of other symptoms such as fever.

[9] Despite general symptoms and problems with the upper respiratory tract (such as high fever, headache, a dry irritating cough followed later by a productive cough with radiographs showing consolidation), there are in general few physical signs ...
A cough is a sudden expulsion of air through the large breathing passages which can help clear them of fluids, irritants, foreign particles and microbes.As a protective reflex, coughing can be repetitive with the cough reflex following three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually ...
Bronchiectasis without CF is known as non-CF bronchiectasis. Historically, about half of all cases of non-CF bronchiectasis were found to be idiopathic, or without a known cause. [25] However, more recent studies with a more thorough diagnostic work-up have found an etiology in 60 to 90% of patients. [24] [26] [27]
The cough may persist for several weeks afterward with the total duration of symptoms usually around three weeks. [2] [1] Some have symptoms for up to six weeks. [3] In more than 90% of cases, the cause is a viral infection. [1] These viruses may be spread through the air when people cough or by direct contact. [2]
