Whether eating and living together will infect syphilis needs to be further analyzed according to the specific situation. If one party suffers from syphilis and there is no sexual contact between the two parties during the period of living together, generally there will be no syphilis infection or a smaller chance of infection; if there is sexual contact with a syphilis patient, there is a greater chance of infection.1. No infection or a smaller chance of infection: When living in separate rooms with a syphilis patient, there is no sharing of rooms, washing and disinfecting intimate clothing separately, not sharing bath towels, toilets, nail clippers, etc., there is generally no syphilis infection. If you live in the same room, but there is no sexual contact, there is a shared toilet, bath towels and other acts, there may be a certain chance of infection, but smaller; 2, the chance of infection is greater: sexual contact with syphilis patients is the main reason for infection with syphilis spirochetes, during the same food and living together, if the cohabiting parties occur without protective measures of sexual contact, or the two sides share sex toys, may make the skin mucous membrane break, at this time the infection The chances of syphilis are higher.
