ICD-10: A38.1

Scarlet fever, clinically known as scarlatina, is an infectious disease primarily caused by group A Streptococcus bacteria, which also lead to other conditions such as strep throat. The ICD-10-CM code A38.1 specifically refers to "Scarlet fever with myocarditis," indicating a serious complication where the infection affects the heart muscle.

Clinical Description of Scarlet Fever

Symptoms

Scarlet fever typically presents with a distinctive rash, fever, and sore throat. Key symptoms include:
- Rash: A red, sandpaper-like rash that usually begins on the neck and face before spreading to the rest of the body.
- Fever: High fever, often exceeding 101°F (38.3°C).
- Sore Throat: Accompanied by redness and swelling, often with white patches on the tonsils.
- Strawberry Tongue: A swollen, red tongue with a bumpy texture.

Pathophysiology

The disease is caused by the release of toxins from the Streptococcus bacteria, which lead to the characteristic symptoms. The infection can also trigger an inflammatory response that may affect various organs, including the heart.

Myocarditis in Scarlet Fever

Definition

Myocarditis is the inflammation of the heart muscle, which can occur as a complication of scarlet fever. This condition can lead to serious cardiovascular issues, including heart failure, arrhythmias, and even sudden cardiac death if not promptly treated.
