ICD-10: A38.9

Scarlet fever, classified under the ICD-10-CM code A38.9, is a bacterial infection primarily caused by group A Streptococcus (Streptococcus pyogenes). This condition is characterized by a distinctive rash and is most commonly seen in children, although it can affect individuals of any age. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description of Scarlet Fever

Etiology

Scarlet fever is caused by the same bacteria that lead to strep throat. The bacteria produce a toxin that results in the characteristic rash and other symptoms associated with the disease. It is important to note that scarlet fever is contagious and can spread through respiratory droplets or direct contact with an infected person's skin lesions.

Symptoms

The clinical presentation of uncomplicated scarlet fever typically includes:

• Fever: Often high, usually above 101°F (38.3°C).
• Sore Throat: Accompanied by redness and swelling.
• Rash: A red, sandpaper-like rash that usually begins on the neck and face before spreading to the rest of the body. The rash may appear within 12 to 48 hours after the onset of fever.
• Strawberry Tongue: The tongue may appear red and bumpy, resembling a strawberry.
• Flushed Face: The face may appear flushed with a pale area around the mouth.

Diagnosis

Diagnosis of scarlet fever is primarily clinical, based on the presence of the characteristic rash and accompanying symptoms. A throat culture or rapid antigen detection test may be performed to confirm the presence of group A Streptococcus.

Treatment

Uncomplicated scarlet fever is typically treated with antibiotics, such as penicillin or amoxicillin, which help to eliminate the bacteria and prevent complications. Symptomatic treatment may also include fever reducers and throat lozenges to alleviate discomfort.

Complications

While uncomplicated scarlet fever generally has a good prognosis with appropriate treatment, complications can arise if left untreated. These may include rheumatic fever, kidney inflammation (post-streptococcal glomerulonephritis), and other infections.

   - A characteristic red rash develops within 12 to 48 hours after the onset of fever. The rash typically starts on the neck, underarm, and groin before spreading to the rest of the body. It has a sandpaper-like texture and may be more pronounced in skin folds (known as "Pastia's lines")[2][3].

4. Strawberry Tongue:
   - The tongue may appear red and bumpy, often referred to as "strawberry tongue," which is a classic sign of scarlet fever[4].

5. Other Symptoms:
   - Additional symptoms may include headache, abdominal pain, nausea, vomiting, and general malaise. Lymphadenopathy (swollen lymph nodes) in the neck is also common[2][3].

Patient Characteristics

• Age:

• Scarlet fever predominantly affects children, particularly those between the ages of 5 and 15 years. However, adults can also contract the disease, especially if they are in close contact with infected children[3][4].

• Seasonality:

• The incidence of scarlet fever tends to increase during the late winter and early spring months, aligning with the peak season for streptococcal infections[3].

• Socioeconomic Factors:

• While scarlet fever can affect individuals from any socioeconomic background, outbreaks are more common in crowded living conditions, such as schools and daycare centers, where the bacteria can spread easily[4].

• History of Streptococcal Infections:

• A history of recurrent streptococcal throat infections may predispose individuals to scarlet fever, as the same bacteria are responsible for both conditions[2][3].
