If you think that you have been in contact with a person who has a STD, you can get checked out at a local private physician's office or at Public Health.
Most STDs can be treated with antibiotics. To kill STD germs, do exactly what your health care provider recommends. Be sure to use all of your medicine. You also must tell your sexual partner(s). If they are not treated, they can spread the STD. They might even give it to you again!
