Pneumonia is a lung infection that can be caused by various bacteria, viruses, or fungi. It typically leads to symptoms such as cough, fever, difficulty breathing, chest pain, and fatigue. In severe cases, pneumonia can cause complications and even be life-threatening, particularly in older adults, young children, and individuals with weakened immune systems. Treatment usually involves antibiotics for bacterial pneumonia, antiviral medication for viral pneumonia, and supportive care to manage symptoms and help the body fight off the infection. Early diagnosis and quick treatment are important to prevent complications and promote recovery.
