Pneumonia, an inflammatory lung condition, arises from bacterial, viral, or fungal infections. It triggers air sac inflammation, filling them with pus and fluids, resulting in symptoms like fever, cough, and breathing difficulties. Classified as community-acquired or hospital-acquired, diagnosis entails clinical assessment, chest X-rays, and lab tests. Treatment involves antibiotics for bacterial and antiviral medications for viralpneumonia, coupled with supportive care. Vaccination mitigates risks. Swift diagnosis and appropriate management are paramount for a positive prognosis, emphasizing the significance of early intervention in alleviating symptoms and preventing complications in individuals affected by this respiratory ailment.
