sphyillis(sti) rule in Singapore

[kisshgs]

Hi I am a foreign student in sg. One day involved in casual sex with online partner and 28 days later doctor told I got infected with syphilis .
So what are the MoM rules for syphilis which was already treated with a shot of antibiotics injection.
Do They will deport me out :'( ?

Secondly during pass conversion/renewal how to prove that syphilis is already treated as all the syphilis test give +ve result even after succesful treatment of syphillis.?

Really confused and depressed
