How long it takes to recover from pneumonia cough is related to the causative pathogen, physical quality and other factors, and the exact time varies from person to person. Pneumonia is a respiratory disease and its symptoms mainly include fever, cough, sputum and chest pain. After a clear diagnosis, if effective anti-inflammatory, cough and expectorant treatment is given in time, the cough symptoms can be gradually relieved in 1-2 days, but the time of complete remission is also related to the infecting pathogen. In the case of pneumonia with common pathogens, recovery usually takes about 1 week, while in patients with poor health it may take about 2 weeks, and the cough symptoms usually disappear after recovery. In pneumonia with pathogens such as mycoplasma and chlamydia, the cough can take up to 3-4 weeks to heal. In the case of chronic bronchitis, emphysema, and in children or elderly patients with low physical fitness, the cough lasts for a relatively long time, in some cases for 1-2 months or more. In addition, patients are advised to maintain good lifestyle habits during the illness, keep warm and avoid getting cold to prevent recurrence of symptoms.
