Scarlet fever: guidance and data
The symptoms, diagnosis, management and epidemiology of scarlet fever (scarlatina).
Scarlet fever occurs most often in the winter and spring. Symptoms include a rash, a sore throat, flushed cheeks and swollen tongue.
Scarlet fever is caused by Streptococcus pyogenes or group A streptococci (GAS) bacteria. Occasionally these bacteria can cause severe and life-threatening diseases.
Scarlet fever is a notifiable disease in England and Wales. This means health professionals must inform local health protection teams of suspected cases.
Diagnosis and management
In many cases, doctors can diagnose scarlet fever from the symptoms alone. If you need confirmation, send a throat swab for bacterial culture to the local microbiology laboratory. In certain cases, serology may also be of value.
