The importance of double lung infection is related to the place of onset and the severity of the disease. Mild community-acquired pneumonia generally has a shorter duration of illness and a quicker recovery. Hospital-acquired pneumonia is more severe and has a longer duration.
Community-acquired pneumonia is pneumonia that occurs outside of the hospital, and clinical improvement generally precedes imaging improvement, with most chest radiographs fully absorbed within 6 weeks. Recovery from simple mild to moderate pneumonia usually occurs in 5 to 7 days. Those with severe or combined other complications have a longer course.
Empiric broad-spectrum antibiotic therapy should be initiated as soon as possible for hospital-acquired pneumonia, and the course of therapy is usually 10 to 14 days, which can be prolonged by severe or immunocompromised or drug-resistant organisms, and up to 4 to 8 weeks in the case of a combined lung abscess or pus thorax.
The prognosis of patients with double-lung infection is also related to factors such as advanced age, multilobar involvement, bacteremia, and severe comorbidities, etc. It is recommended to go to the hospital as soon as possible and cooperate with the doctor for standardized treatment to strive for early recovery.
