query: How do you cure Scarlet fever?
passage: Scarlet fever
Antibiotics to combat the streptococcal infection are the mainstay of treatment for scarlet fever. Prompt administration of appropriate antibiotics decreases the length of illness. Peeling of the outer layer of skin, however, will happen despite treatment.[7] One of the main goals of treatment is to prevent the child from developing one of the suppurative or nonsuppurative complications, especially acute rheumatic fever.[16] As long as antibiotics are started within 9 days, it is very unlikely for the child to develop acute rheumatic fever.[13] Antibiotic therapy has not been shown to prevent the development of poststreptococcal glomerulonephritis.[14][7] Another important reason for prompt treatment with antibiotics is the ability to prevent transmission of the infection between children. An infected individual is most likely to pass on the infection to another person during the first 2 weeks.[18] A child is no longer contagious (able to pass the infection to another child) after 24 hours of antibiotics.[13]

Serologic testing looks for the antibodies that the body produces against the streptococcal infection including antistreptolysin-O and antideoxyribonuclease B. It takes the body 2–3 weeks to make these antibodies so this type of testing is not useful for diagnosing a current infection. However, it is useful when assessing a patient who may have one of the complications from a previous streptococcal infection.[12][16]
