syphilis window

The window period is the time between infection and laboratory detection of a disease. The window period for syphilis is usually six weeks, meaning that if the patient is positive for syphilis, it means that the patient has been infected at least six weeks ago. If the patient is negative at this time, it can only represent that the patient was not infected with Treponema pallidum 6 weeks ago, and cannot represent the symptoms of the last 6 weeks. It must be checked after 6 weeks of infection, otherwise it is meaningless and cannot explain any problems.
