Both HIV and syphilis tests are performed by drawing blood for HIV antibodies and syphilis antibodies. Generally, if the HIV antibody is positive, further retesting at the CDC is required at this time. If the test is positive twice, the diagnosis of HIV infection is usually made. For such cases, patients need to go to the CDC for drug antiviral treatment in a timely manner. In addition, for patients who are positive for syphilis, blood sedimentation and other tests are also required if they are in the acute phase. If the diagnosis is made in the acute stage, active treatment with antibacterial drugs, such as long-acting penicillin injections, is required if necessary. However, if the syphilis has been infected before, the lifelong antibodies are usually positive and it is not necessarily an acute infection. Therefore, patients should distinguish whether the infection is acute or whether the antibodies are formed as a result of the infection. Generally, after the formation of antibodies, the patient’s syphilis is mostly in the quiescent phase and does not show the acute phase.
