How long does it take to cure an Escherichia coli infection is related to the patient’s personal constitution, the severity of the disease and other factors, usually it can be cured in about 1~2 weeks, or it may take longer in severe cases. Escherichia coli, also called E. coli, is a normal flora in the human intestinal tract, which usually does not lead to disease. However, if the patient has an imbalance of intestinal flora or low immunity, E. coli will grow abnormally, leading to gastrointestinal infections, and urinary tract infections such as urethritis and cystitis, and may also induce pneumonia in newborns. After the emergence of E. coli infection usually need to apply antibiotics for anti-infection treatment, commonly used antibiotics include cephalosporin, norfloxacin, etc., the specific use of which antibiotics should be based on the results of the sensitivity of the rational choice. How long will it take to cure the disease is related to the patient’s physical condition and the severity of the disease, and cannot be generalized. If the patient’s physical condition is better, the condition is milder, the treatment is more timely, usually in 3~7 days can be effectively controlled; if the patient’s condition is more serious, the physical condition is worse, the time needed will be relatively longer, may need 1~2 weeks, or even longer. Patients with Escherichia coli infection are advised to seek timely medical attention and actively receive treatment to avoid delays.
