Perianal (say "pair-ee-AY-nal") strep is an infection of the skin around the anus. This is the opening where stool leaves the body. The infection causes a bright red rash around the anus. It can sometimes spread into the genital area. The rash is moist and much redder than diaper rash.
The infection is caused by bacteria called streptococcus. This is the same bacteria that causes strep throat. The area is often infected when your child or another person gets the bacteria on his or her hands and then touches the area.
This infection can spread easily, so you and your child will need to be careful not to spread it to others. You can do this by washing your hands with soap and water after touching the affected area. Make sure your child washes his or her hands with soap and water after touching the rash, too.
Your doctor will prescribe antibiotics. He or she may also prescribe an ointment or cream.
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if your child is having problems. It's also a good idea to know your child's test results and keep a list of the medicines your child takes.
