Syphilis
If people do certain things, they are more likely to get syphilis. Medical professionals say that these people should get tested regularly. For example, the CDC says that men who have sex with men should be tested at least every year. Getting tested regularly helps prevent syphilis from being spread. If a person is tested and finds out that they have syphilis, they are more likely to get treatment, and will not accidentally spread syphilis to other people.
