Secondary pneumonia generally refers to all pulmonary inflammatory complications in the case of systemic or pulmonary diseases, which may be caused by the spread of microorganisms in the original lesions outside the lung into the lung, while the original diseases cause the decline of systemic or pulmonary resistance, and the secondary pneumonia caused by the invasion of resident bacteria in the body into the lung tissue is more common.
