Can I get a health certificate if I have syphilis?

You can't get a health certificate if you have syphilis. Syphilis is a common sexually transmitted disease, caused by Treponema pallidum infection. At the initial stage, syphilis is characterized by painless ulcer of pudendum, which usually begins to appear from 10 to 3 months after infection. The incubation period is 2 ~ 3 weeks. Syphilis is a chronic sexually transmitted disease caused by Treponema pallidum. It can invade skin, mucous membrane and many other tissues and organs.
