I am so comforted by the facts that I was tested at least three times in my life to determine if I had any non-symptomatic venereal disease and none was found. Also, I was treated with antibiotics for other diseases that would have wiped out any lingering venereal infections anyway. 4nos might want to be screened just for his own self-confidence, because he certainly exhibits symptoms of what a concerned care-giver might not be able to eliminate as possibly arising from tertiary syphilis here every day.
