Circumcision is also a kind of surgery, so it is also checked for AIDS, in fact not only for AIDS, but also for hepatitis B, hepatitis C and syphilis. Because these are common infectious diseases, as long as the surgery is done, these infectious diseases will be checked, because it is possible to get infected with these diseases, so it is important to be checked for these infectious diseases before the surgery. Otherwise, if there is an infection after the surgery, there is no way to clarify whether the patient was infected during the surgery or before the surgery. Therefore, screening for these infectious diseases should be routinely performed for any surgery to avoid the possibility of medical disputes when the infection eventually occurs and it is not clear when the patient was infected. Of course, the vast majority of patients who undergo surgery are not infected with these diseases.
