Bacterial infections in children can take anywhere from a week to half a month to treat, as children’s bodies and the extent of their illnesses vary, so it’s not possible to generalize. Bacterial infections are usually treated according to the location of the infection. If the condition is mild and the child cooperates with his or her doctor, he or she will recover in a week or so. If the condition is more serious and treatment is not timely, recovery may take longer, perhaps half a month or more. In addition, if there are other symptoms, further treatment is needed, such as coughing, coughing up phlegm, etc., must follow the doctor’s instructions to take the phlegm and cough drugs, such as aminoglutethimide hydrochloride, acetylcysteine and so on. If accompanied by high fever, sweating and other symptoms, must follow the doctor’s instructions anti-infection, rehydration therapy, such as cefixime and other antibiotics for anti-infection treatment. Because of the different specific conditions of individuals, the recovery time will be different, parents need to have patience and actively cooperate with the doctor’s treatment, and strive for early recovery. All of the above drugs should be used under the guidance of a doctor to avoid the adverse consequences of self-medication.
