Scarlet fever

scarlet; fever; ;

Scarlet fever is an illness caused by bacteria (germs) that usually just cause an infection of the throat ('strep' throat). A streptococcal ('strep') sore throat is a bacterial infection of the throat and tonsils. The symptoms include fever, sore throat and tender, swollen glands in the neck.

Toxins (poisons) that are sometimes released by the bacteria may cause scarlet fever and also may cause damage to other parts of the body. Rarely the toxin may cause

  • Rheumatic fever (causing damage to the heart)
  • Glomerulonephritis (damage to the kidneys).

Quinsy - an abcess (collection of pus) next to a tonsil - may also occur.

The bacteria causing the infection need to be treated with antibiotics (often penicillin) to prevent these complications.
