A chest infection occurs when the lungs or airways become inflamed due to bacteria, viruses, or fungi, leading to conditions like bronchitis or pneumonia. Common symptoms include cough with mucus, chest pain, fever, shortness of breath, and fatigue. It can range from mild to severe, especially in individuals with weak immunity. Treatment depends on the cause and may include antibiotics, antivirals, breathing exercises, and supportive care. Early diagnosis is crucial to prevent complications.
