Signs of pneumonia breathing in
Pneumococcal pneumonia can infect the upper respiratory tract and can spread to the blood, lungs, middle ear, or nervous system. Signs of pneumonia include cough with sputum production, fever, and sharpchest pain on inspiration (breathing in). Pneumonia is due primarily to infections, with less common causes including irritants and the unknown. Because pneumonia is common and is associated with significant morbidity and mortality, properly diagnosing pneumonia, correctly recognizing any complications or underlying conditions, and appropriately treating patients are important.
It is important to note that older people may have fewer or different symptoms than younger people. Pneumonia caused by bacteria tends to be the most serious kind. Pneumonia also affects the tiny airways that lead into the alveoli, causing them to swell closed and obstruct air flow.
