English: Syphilis is a rare STI caused by a bacteria. It’s transmitted mainly through unprotected sex where mucous membranes and body fluids come in contact The disease is uncommon, but the number of infected people has increased over the past few years. Syphilis can be symptom-free, but is contagious at an early stage, which is why you should get tested if you’re in doubt. The first symptom usually is one or a few wounds where you have been infected. If the infection isn’t detected in time, it can lead to severe complications many years after a healed infection. These include symptoms from the heart and nervous system. If a pregnant person is infected, the infection can be passed on to the fetus during pregnancy. Syphilis is treatable and you can make a full recovery.
