After a few days, the rash and fever disappeared and she is now back in school. Her principal's daughter developed the exact same symptoms and was taken to the doctor. She has scarlet fever and is on antibiotics. My question is: my friend doesn't have a family doctor. Can her daughter still have scarlet fever, even without symptoms (except cold symptoms). Will it go away without antibiotic treatment? What about developing into rheumatic fever? Any help will be appreciated. Missy Answer: The combination of Strep throat and the rash associated with it is called Scarlet Fever. The treatment is antibiotics (usually Penicillin or similar antibiotic if the child is Penicillin allergic). It is quite possible that the child did have Scarlet Fever, however, the immune system has a wonderful capacity for containing the illness. In other words, antibodies where produced in response to the bacteria, almost like treating itself. This does not mean that we should ignore symptoms and hope that the body takes care of it. Rheumatic Fever can occur when a Strep/Scarlet Fever is not treated. Although symptoms may disappear, it may affect certain organs such as the heart, it's valves and blood vessels. The results of untreated infection may not appear until much later in life. It would be in the best interest to encourage a visit a physician for your friends daughter, even if all her symptoms are gone. A quick test for Strep can be performed in the office. Rheumatic Fever is not as common today as it was years ago. This is because of earlier treatment. Also see: My 10 year old daughter is incredibly prone to insect bites. Even when no one else is getting bitten, they seem to go for her! Any suggestions? My 12 year old daughter experiences difficulty sleeping due to fear of the dark and being alone. Is this normal?
