Strep Pharyngitis (Strep Throat)
Strep pharyngitis, commonly known as strep throat, is a bacterial infection caused by Group A Streptococcus. It typically affects school-aged children and spreads easily through coughing, sneezing, or shared utensils.
At The Medical Group of New Jersey, our pediatricians provide quick, accurate testing and targeted antibiotic treatment to relieve symptoms, prevent complications, and reduce the spread of infection. With prompt care, most children recover fully within a few days.
Symptom Onset & Initial Evaluation
Symptoms often begin suddenly and can be more intense than a typical viral sore throat. Common signs include:
- Sudden sore throat and painful swallowing
- Fever and swollen glands in the neck
- Red, inflamed throat with white patches or streaks of pus
- Headache, stomach pain, or nausea
- Fatigue and loss of appetite
Unlike viral sore throats, strep infections usually do not cause cough, runny nose, or hoarseness.
During your visit, your pediatrician will review recent exposures (such as classmates or siblings with strep) and perform a gentle throat examination to look for inflammation or enlarged tonsils.
Diagnosis
Accurate diagnosis helps ensure appropriate treatment and prevents unnecessary antibiotic use. Testing typically includes:
- Rapid strep test: Provides results in minutes to confirm Group A Streptococcus.
- Throat culture: May be sent to the lab if the rapid test is negative, but suspicion remains high.
At The Medical Group of New Jersey, our pediatric offices offer on-site testing for fast, same-day results, so children can begin treatment and return to school as soon as safely possible.
Treatment & Ongoing Management
Once strep throat is confirmed, treatment is straightforward and highly effective.
Antibiotic Therapy
- A full course of antibiotics (usually penicillin or amoxicillin) is prescribed to eliminate infection and prevent complications such as rheumatic fever.
- For penicillin-allergic children, alternative antibiotics (like azithromycin or cephalexin) are used safely.
Symptom Relief
- Acetaminophen or ibuprofen can ease sore throat pain and reduce fever.
- Encourage hydration—warm fluids like broth or tea can soothe discomfort.
- Soft foods and rest support faster recovery.
Children typically start feeling better within 24 to 48 hours of starting antibiotics.
Prevention & Family Guidance
To prevent reinfection or spread to others:
- Replace your child’s toothbrush after 24 hours of antibiotic use.
- Wash hands frequently and avoid sharing utensils or drinks.
- Keep children home from school or daycare until at least 24 hours after starting antibiotics and once they are fever-free.
- Clean frequently touched surfaces like door handles and phones.
Your pediatrician at The Medical Group of New Jersey will also provide guidance for families with multiple children, especially when exposure risk is high.
Follow-Up & Long-Term Outlook
Most children recover completely within a few days. A follow-up visit is typically not required unless symptoms persist, worsen, or recur.
Call your pediatrician or seek urgent medical care if your child experiences:
- Ongoing fever after 48 hours of antibiotics
- Difficulty swallowing or breathing
- New rash, which may indicate scarlet fever or a medication reaction
With timely diagnosis and treatment, strep throat rarely causes complications. Preventive hygiene and consistent pediatric follow-up ensure your child remains healthy and protected from recurrence.
