The recovery time for bacterial pneumonia is related to the causative organism, the severity of the disease, and the patient’s own resistance, and is usually about 2 weeks. Pneumonia caused by Streptococcus pneumoniae is usually cured in 2 weeks with penicillin treatment; pneumonia caused by Staphylococcus aureus is cured in 2-4 weeks with semi-synthetic penicillin or cephalosporin treatment; pneumonia caused by Klebsiella pneumoniae is cured in 2 weeks with aminoglycoside antibiotics. Usually for non-resistant bacterial infections, the cure time is 1-2 weeks; for severe pneumonia it is more than 2 weeks when it is cured; for severe pneumonia due to drug-resistant bacterial infections, the treatment time is about 4 weeks. If the patient’s resistance is weak, the recovery time will be extended accordingly. In addition, patients should also choose a high-protein, high-calorie, and high-vitamin diet during treatment, while paying attention to rest, drinking plenty of water, and avoiding getting cold.
