What is Scarlet Fever?

Scarlet fever, also known as scarlatina, is a bacterial illness that affects some people who have strep throat. It is characterized by a bright red rash, which can appear on the skin all over the body.

Symptoms of Scarlet Fever

The symptoms of scarlet fever typically begin with a fever and sore throat. The illness may also be accompanied by chills, vomiting, abdominal pain, and malaise (a general feeling of being unwell). A distinctive pink-red rash appears on the skin, which can feel like sandpaper to the touch.

Causes of Scarlet Fever

Scarlet fever is caused by an infection with bacteria called group A streptococcus. This is the same type of bacteria that causes strep throat. The illness is highly contagious and can spread quickly among children in schools or other close-knit communities.

Treatment of Scarlet Fever

Fortunately, scarlet fever is easily treated with antibiotics. Prompt medical attention is essential to prevent complications and ensure a full recovery.

Key Facts about Scarlet Fever

• Age group affected: Scarlet fever mainly affects young children.
• Contagiousness: The illness is highly contagious and can spread quickly among children in schools or other close-knit communities.
• Treatment: Scarlet fever is easily treated with antibiotics.
• Complications: If left untreated, scarlet fever can lead to complications such as kidney disease, rheumatic heart disease, and pneumonia.

Common Signs and Symptoms of Scarlet Fever

Scarlet fever, also known as scarlatina, is a bacterial infection caused by Group A Streptococcus (GAS). The first signs and symptoms to appear are usually fever and sore throat. Here are the common signs and symptoms of scarlet fever:

• Fever: A high temperature, typically above 101°F (38.3°C) [1]
• Sore Throat: A red, sore throat is a hallmark symptom of scarlet fever [2][6]
• Rash: A red, bumpy rash that feels rough like sandpaper appears on the skin, often starting on the chest and spreading to other areas [1][3][7]
• Swollen Neck Glands: Enlarged lymph nodes in the neck can be a symptom of scarlet fever [4]
• Loss of Appetite: Many people with scarlet fever experience a decrease in appetite [4]
• Nausea or Vomiting: Some individuals may feel queasy or vomit due to the infection [5][9]

Other Possible Symptoms

In addition to these common symptoms, some people may also experience:

• Chills
• Headache
• Stomach pain
• Coated white tongue (in children)
• Strawberry-like color of the tongue (in children)

It's essential to seek medical attention if you or your child is experiencing any of these symptoms. A healthcare professional can diagnose scarlet fever through a physical examination and laboratory tests.

Diagnostic Tests for Scarlet Fever

Scarlet fever, also known as scarlatina, is a bacterial infection caused by Group A Streptococcus (GAS). The diagnosis of scarlet fever typically involves a combination of clinical evaluation and laboratory tests. Here are some of the diagnostic tests used to confirm the presence of scarlet fever:

• Physical examination: A thorough physical examination is essential in diagnosing scarlet fever. This includes looking for symptoms such as a sore throat, fever, headache, and a characteristic rash (1).
• Throat culture: A throat culture is a laboratory test that involves taking a sample from the back of the throat to check for the presence of Group A Streptococcus bacteria (2). This test can confirm the diagnosis of scarlet fever.
• Rapid antigen detection test: A rapid antigen detection test, also known as a rapid strep test, is a quick and simple test that involves taking a sample from the back of the throat to check for the presence of Group A Streptococcus antigens (3). This test can help confirm the diagnosis of scarlet fever.
• Urinalysis: Urinalysis may be performed to rule out other conditions or complications associated with scarlet fever, such as kidney problems (4).
• Liver function tests: Liver function tests may also be performed to check for any liver damage caused by the infection (4).

Treatment Options for Scarlet Fever

Scarlet fever, also known as scarlatina, is a bacterial infection caused by Group A Streptococcus (GAS). The primary goal of treatment is to eliminate the bacteria and alleviate symptoms. Here are some key points about drug treatment for scarlet fever:

• Antibiotics: Antibiotic therapy is the recommended treatment for scarlet fever. Penicillin or amoxicillin is typically prescribed as the first-line antibiotic, with a 10-day course being the standard duration [2][3].
• Penicillin V: Oral penicillin V is another commonly used antibiotic to treat scarlet fever [4].
• Amoxicillin: Amoxicillin is often prescribed in liquid or tablet form for children and adults alike [5].
• Antistreptococcal antibiotic levels: Treatment aims to provide adequate antistreptococcal antibiotic levels for at least 10 days to effectively eliminate the bacteria [6].

Additional Information

It's essential to note that treatment for scarlet fever is aimed at eliminating the bacterial infection, not just alleviating symptoms. In some cases, additional medications may be prescribed to help manage symptoms such as fever and throat pain.

The differential diagnosis of scarlet fever involves considering other conditions that can present with similar symptoms, such as a rash and fever.

Conditions to consider:

• Viral exanthems: These are skin rashes caused by viral infections, which can be similar in appearance to the rash seen in scarlet fever [6].
• Kawasaki disease: This is a rare condition that affects children and can cause a rash, fever, and swelling of the lymph nodes [6].
• Staphylococcal toxic shock syndrome: This is a life-threatening condition caused by bacterial toxins, which can present with a rash, fever, and other systemic symptoms [6].
• Allergic reactions: Certain allergic reactions, such as an allergic reaction to a medication or food, can cause a rash and fever that may be similar to scarlet fever [7].

Other considerations:

• Streptococcal pharyngitis: This is an infection of the throat caused by group A beta-hemolytic streptococci (GABHS), which can present with symptoms similar to scarlet fever, including a sore throat and rash [8].
• Mononucleosis: This is a viral infection that can cause a rash, fever, and other systemic symptoms, which may be mistaken for scarlet fever [8].

Key diagnostic factors:

• A scarlatiniform rash (a rash that resembles the one seen in scarlet fever) is a key diagnostic factor for differentiating scarlet fever from other conditions [7].
• Fever above 100.4°F (38.0°C) is also an important diagnostic factor [7].

It's essential to note that scarlet fever is caused by infection with group A beta-hemolytic streptococci (GABHS), and a definitive diagnosis can be made through laboratory tests, such as throat culture or rapid antigen testing.
