Both novel coronavirus pneumonia and bacterial pneumonia are infectious diseases of the respiratory system that are characterized by inflammation of the lungs. The causative agent of novel coronavirus pneumonia is the novel coronavirus, and the causative agent of bacterial pneumonia is bacteria, which can be Streptococcus pneumoniae, Legionella, and others. Novel Coronavirus Pneumonia must have the opportunity to be infected by the Novel Coronavirus, such as contact and entry into an infected area. Bacterial pneumonia may tend to be contracted when the body’s resistance is weaker or when it is infected by bacteria. The clinical manifestations may all be characterized by coughing, fever or the development of dyspnea. Viral pneumonia or novel coronavirus pneumonia begins with the lungs may show multiple ground-glass shadows in the outer bands of the lungs. Novel coronavirus pneumonia is treated primarily with antiviral, and bacterial pneumonia is treated primarily with antibiotics and anti-inflammatory drugs. New coronavirus pneumonia may have an incubation period from infection to onset, such as almost two days or two weeks of incubation process, while bacterial pneumonia from infection to onset within a few days will occur, the incubation period is relatively short. The new coronavirus pneumonia is contagious, after being infected itself is contagious, medical personnel should be strictly protected. Bacterial pneumonia is less likely to be contagious to healthy people. Bacterial pneumonia can be effectively controlled with effective antibiotic treatment, while new coronavirus pneumonia, if it is severe or critical, often requires more aggressive treatment, and the effective treatment also depends on its own antiviral treatment, along with the recovery of its own immune system, in order to be able to effectively control the disease.
