A cold can cause pneumonia because it is an upper respiratory tract infection. A more severe cold or poor health of the patient can spread pathogens to the lower respiratory tract and can lead to the development of a lung infection. Fever is only a clinical symptom that is part of the body’s stress response, so fever does not usually lead to pneumonia. The antecedent symptomatic manifestation of many pneumonia patients is a cold. These patients should be treated with active anti-inflammatory therapy, and sensitive antibiotics can be selected based on the patient’s sputum bacterial culture and drug sensitivity test results, and can also be combined with antiviral drugs and cold medications.
