Syphilis

Syphilis is a sickness caused by a little critter called a bacteria. This bacteria spreads from person to person through close contact - like touching or having intimate relations with someone who has it.

When the bacteria goes into your body, it can make you feel sick for a while. Some people might get a sore like a boo-boo where the bacteria goes in, but sometimes you won't even notice anything at first.

If the bacteria isn't treated, it can be very bad for you. It can harm your brain, heart, and other important parts of your body.

Doctors can give you medicine to help the boo-boo go away and stop the bacteria from hurting your body. It's important to see a doctor if you think you might have syphilis. And remember, the best way to avoid getting sick is to not have close contact with people who have syphilis.
