The duration of treatment for pneumonia depends on the pathogen that infected the pneumonia, including viruses, bacteria, mycoplasma, etc. The duration of treatment is usually 10-14 days in most patients, with a few patients requiring 1 month or more. The most common clinical condition is lobar pneumonia, caused by Streptococcus pneumoniae infection. If there are no serious complications, the inflammatory shadow can gradually disappear within 10 days after proper etiologic treatment. In the case of pneumonia caused by specific pathogens, such as Legionella, the treatment time can be relatively prolonged, usually about 3 weeks. In addition to oral antibiotics, patients with prolonged pneumonia or chronic pneumonia also need to be treated with herbal tonics to clear the lungs and to strengthen the immune system, which requires a longer treatment time. In addition, patients with pneumonia should be given attention to drainage of sputum, supplementation of nutrition, and patients need to drink more water, and patients with high fever can take physical cooling methods to reduce fever.
