The rash tends to spread to the extremities and can result in peeling skin on the palms of the hands. Patients present with varying severity. The key differentiating factor from other diseases with a rash such as measles and rubella is the lack of upper respiratory inflammation.

As treatment involves administration of a course of antibiotics, it is important to ensure accurate diagnosis, usually by an oral swab to confirm the presence of bacteria and avoid misdiagnosis of other viral conditions such as roseola. The recommended treatment is Penicillin as a 10-day course, however, other options are available for patients who are allergic to penicillin for example Azithromycin as a 5-day course. The dose is determined by age.
