Viral pneumonia is more common in winter and spring, and can be sporadic or epidemic. The main clinical manifestations are fever, general pain, dyspnea and pulmonary infiltration in a few cases. Viral pneumonia is related to virus virulence, infection route, host age and immune status.

Influenza virus is the most common virus that causes viral pneumonia, and there are parainfluenza virus, cytomegalovirus, adenovirus, rhinovirus and coronavirus. Diagnosis depends on etiological examination, including virus isolation, serological examination and virus antigen and nucleic acid detection.

The disease can be prevented and controlled, and indoor air circulation should be maintained in prevention, avoiding closed unventilated public places and crowded places, and wearing masks when going out. Clinically, symptomatic treatment is the main treatment, and bed rest is needed. If you have the above symptoms, especially persistent fever, you should go to a medical institution in time.
