Lung Infections(Pneumonia)
Pneumonia is an infection of the lungs that causes inflammation in the air sacs (alveoli), which may fill with fluid or pus. It can be caused by bacteria, viruses, fungi, or other microorganisms. Common symptoms include cough, fever, chills, shortness of breath, chest pain, fatigue, and sometimes vomiting or confusion in older adults. Pneumonia can range from mild to life-threatening, especially in infants, elderly people, and those with weakened immune systems or chronic illnesses. Early recognition and treatment are critical for preventing serious complications.
Diagnosis involves physical examination, chest X-rays, blood tests, and sometimes sputum cultures to identify the causative organism. Treatment depends on the type of pneumonia and may include antibiotics, antiviral or antifungal medications, supportive care, and hospitalization in severe cases. Preventive measures such as vaccination, good hygiene, and avoiding smoking can significantly reduce the risk of lung infections.
