If you are still wondering and questioning yourself what could be worst scenario after having one night stand, unprotected sex (vaginal, anal, oral sex) or after you have returned from holiday/weekend where you have had intercourse with a random sexual partner you should make sure to test your self on Syphilis ASAP!
If you feel ashamed by going to visit your doctor you can still test on Syphilis at home with 98% accuracy! Within 15 minutes you will get answer either your test is positive/negative.
Symptoms usually appear about two to three weeks after infection. Even after a recent exposure to the bacteria, the result may be negative, and it does not exclude the presence of infection. Thus, if the results were negative, but you still have your doubts, repeat the test after one month with a new test kit. The disease can sometimes proceed without a rash, in a so-called "hidden" form.
Think about what danger untreated syphilis causes to your health and avoid this risk. For example, uncontrollable changes may occur in your brain, nervous system and cardiovascular system. Or in case you are/will become pregnant with untreated syphilis you can infect the foetus, but the infection can also happen during childbirth.
Remember as syphilis can sometimes pass without any signs of disease or with only subtle signs, it is recommended for those who often have different sexual partners to periodically (e.g. twice a year) check themselves.
