Clinical Features of Scarlet Fever (Scarlatina)

Does the patient have pharyngitis or other infection caused by Streptococcus pyogenes?

Did a diffuse erythematous rash appear after the onset of fever and localized signs of infection?

Does the rash blanch on pressure?

Did the rash start on the upper chest and then spreads distally?

Are the palms and soles spared from the rash?

Are skin folds dark red in color (Pastia's lines)?

Is the face flushed with circumoral pallor?

Does the tongue show a whitish coating or a beefy red appearance?

Does the skin have a sandpaper-like feel when rubbed?

During recovery has the patient developed a diffuse skin desquamation?

Is there another condition that can explain the findings better?
