There is no specific value for the treatment time of lung abscesses infected by Enterococcus faecalis, but the treatment time is relatively shorter for patients with milder conditions, and longer for patients with more severe conditions. If the patient’s condition is mild, the area of bacterial infection is small, the abscess is relatively light, and the patient’s physical condition is good and there are no other concurrent diseases. The treatment will be relatively simple, the prognosis of the treatment is better, and the duration of the disease will be shortened. If the patient’s condition is more serious, the scope of abscess has been expanded to involve the surrounding tissues of the lungs, and the patient’s own physical condition is poor, it is easy to be complicated by complications such as pyothorax and hemoptysis. At this time, the treatment will be relatively complicated, the therapeutic effect and prognosis are uncertain, and the recovery time may become long. To sum up, how long does it take to treat lung abscess infected by Enterococcus faecalis need to be judged according to the patient’s own condition, not generalized, and it is recommended that the patient go to the hospital in time for treatment, and the specific time should be based on the doctor’s advice.
