Pneumonia is a respiratory tract infectious disease that requires the timely selection of antimicrobial drugs and anti-inflammatory treatment, as well as the choice of symptomatic treatment medications. Symptoms of pneumonia include fever, headache, nausea, sore throat, cough, expectoration, chest pain, and difficulty breathing. The pathogens causing the infection vary, and so do the antibiotics used to treat them. For common bacterial infections, penicillin antibiotics or cephalosporin antimicrobial drugs can be selected. During an acute fever phase, antipyretic analgesics may be chosen or physical cooling methods may be employed.
