Etiology
- Group A strep pharyngitis is an infection of the oropharynx caused by S. pyogenes. S. pyogenes are gram-positive cocci that grow in chains (see figure 1). They exhibit β-hemolysis (complete hemolysis) when grown on blood agar plates. They belong to group A in the Lancefield classification system for β-hemolytic Streptococcus, and thus are called gr...
Clinical Features
- Group A strep pharyngitis is an acute pharyngitis that commonly presents with 1. Sudden-onset of sore throat 2. Odynophagia 3. Fever Other symptoms may include headache, abdominal pain, nausea, and vomiting — especially among children. Patients with group A strep pharyngitis typically do not typically have cough, rhinorrhea, hoarseness, oral ulcers, or conjunctivitis. These …
Transmission
- Group A strep pharyngitis is most commonly spread through direct person-to-person transmission. Typically transmission occurs through saliva or nasal secretions from an infected person. People with group A strep pharyngitis are much more likely to transmit the bacteria to others than asymptomatic pharyngeal carriers. Crowded conditions — such as those in schools, …
Risk Factors
- Group A strep pharyngitis can occur in people of all ages. It is most common among children 5 through 15 years of age. It is rare in children younger than 3 years of age. The most common risk factor is close contact with another person with group A strep pharyngitis. Adults at increased risk for group A strep pharyngitis include: 1. Parents of school-aged children 2. Adults who are often …
Diagnosis and Testing
- The differential diagnosis of acute pharyngitis includes multiple viral and bacterial pathogens. Viruses are the most common cause of pharyngitis in all age groups. Experts estimate that group A strep, the most common bacterial cause, causes 20% to 30% of pharyngitis episodes in children. In comparison, experts estimate it causes approximately 5% to 15% of pharyngitis infe…
Special Considerations
- Clinicians should confirm group A strep pharyngitis in children older than 3 years of age to appropriately guide treatment decisions. Giving antibiotics to children with confirmed group A strep pharyngitis can reduce their risk of developing sequela (acute rheumatic fever). Testing for group A strep pharyngitis is not routinely indicated for: 1. Children younger than 3 years of age 2…
