Open mouth with a so called strawberry tounge that hints at scarlet fever. Scarlet fever is an infection caused by bacteria (Steptococci) that occurs mostly in children.
The typical symptoms are caused by a toxin that is produced by a phage inside the bacteria. The illness leaves immunity against the toxin, but another infection with streptocicci can occur.
Scarlet fever begins suddenly with high fever and sore throat and maybe other uncharacteristic symptoms. On the second day the rash and the strawberry tounge appear. The tounge seems swollen and the mucosa reddened.
Feared complications are a septic course of the disease and long term damage from the toxins and heart - rheumatic fever, kideny - glomerulonephritis.
