Is syphilis saliva contagious?

Syphilis is a chronic sexually transmitted disease caused by Treponema pallidum. The only source of syphilis infection is syphilis patients, mainly through sexual, vertical transmission and other ways to spread. Other ways refer to transmission through other ways than sexual, including direct contact, indirect contact, etc.: direct contact has kissing, breastfeeding, etc. Saliva if direct or indirect contact is possible. Indirect contact is also one of the other routes. It refers to contact with articles of daily use that cause infectious damage to the patient, such as clothing, towels, cutlery, cigarette holders, etc. Syphilis can also be transmitted vertically. Pregnant women with syphilis may infect the fetus through the placenta. The most important route of transmission of syphilis is sexual contact. Untreated patients are most infectious within a year of infection, with large numbers of Treponema pallidum on the surface of skin and mucosal lesions, which are easily transmitted through skin and mucosal lesions during sexual contact.
