Syphilis spirochete resistance to the outside world is very weak, the chemicals are also very sensitive, outside the body is not easy to survive, boiling, drying, soapy water and general disinfectants (such as mercury, carbolic acid, Lysol, alcohol, 1:1000 potassium permanganate solution, etc.) is very easy to kill it, sunlight irradiation and dry environment can quickly make it die. Syphilis spirochetes generally survive outside the human body for more than 1 to 2 hours. It can survive for a few days in an oxygen-deprived environment, a few hours on damp clothing, and generally 24 hours in a blood bank. The syphilis spirochete does not tolerate high temperatures, and can die in 2 to 3 minutes at 40℃ to 60℃, and instantly at 100℃. The syphilis spirochete can be eliminated by targeting its weakness. For example, putting clothes in the sun and storing them in a dry environment; boiling and sterilizing utensils or sterilizing them with chemicals can kill the syphilis spirochete and stop its spread.
