What Is Strep Throat?
Streptococcal pharyngitis — commonly called strep throat — is a bacterial infection of the throat and tonsils caused by Streptococcus pyogenes (Group A Streptococcus). It accounts for 20–30% of sore throat cases in children and 5–15% in adults, and is one of the most common reasons patients seek urgent medical care. Unlike viral sore throats caused by rhinovirus or adenovirus, strep throat requires antibiotic treatment to prevent serious complications.
Left untreated, Group A strep can progress to serious conditions including rheumatic fever, which can permanently damage heart valves, and post-streptococcal glomerulonephritis, a form of kidney inflammation. These complications are entirely preventable with a timely course of antibiotics — making prompt diagnosis and treatment critically important.
At Innocre Telehealth, our board-certified provider, evaluates your symptoms, reviews your history, and can prescribe antibiotics directly to your pharmacy during your same-day video visit. Our clinical evaluation follows evidence-based guidelines from the Infectious Diseases Society of America (IDSA).
Common Symptoms of Strep Throat
Sudden-onset, intense pain that worsens with swallowing
High fever is a classic hallmark distinguishing strep from viral illness
Odynophagia — painful swallowing — is prominent with bacterial pharyngitis
Erythematous tonsils, often with exudate visible on the surface
Whitish or yellowish tonsillar exudate strongly associated with Group A strep
Tender anterior cervical lymphadenopathy is a key diagnostic criterion
Absence of cough is a classical Centor criterion suggesting bacterial rather than viral cause
Systemic symptoms including headache, nausea, and general malaise are common
How Innocre Treats Strep Throat Online
During your telehealth visit, your provider will conduct a structured clinical assessment using validated scoring tools such as the modified Centor score (McIsaac criteria), which weighs fever, tonsillar exudate, lymphadenopathy, absence of cough, and patient age to estimate the probability of Group A strep infection. You may be asked to open your mouth and illuminate your throat with a flashlight for visual inspection.
If clinical criteria support strep throat, antibiotic therapy will be prescribed directly to your preferred pharmacy. The first-line treatment for Group A streptococcal pharyngitis per IDSA guidelines is amoxicillin (500 mg twice daily for 10 days for adults) or penicillin V. For patients with confirmed penicillin allergy, azithromycin (a 5-day Z-pack course) or cephalexin are appropriate alternatives. Pain and fever can be managed with acetaminophen or ibuprofen.
It is important to complete the full antibiotic course even when you feel better after 2–3 days, as incomplete courses can allow bacterial persistence and increase resistance risk. Patients typically become non-contagious within 24 hours of starting antibiotics and can resume normal activities if fever has resolved.
⚠️ When to Go to the Emergency Room
Seek emergency care immediately if you or a family member experiences any of the following:
- •Difficulty breathing or stridor — any obstructed airway is a life-threatening emergency requiring 911
- •Drooling or inability to swallow saliva — may indicate epiglottitis or a peritonsillar abscess requiring drainage
- •Severe neck stiffness with fever — this combination raises concern for bacterial meningitis, a neurological emergency
- •Muffled "hot potato" voice with one-sided throat swelling — classic signs of peritonsillar abscess requiring in-person drainage
- •Trismus (jaw locking) or inability to open the mouth — may signal deep space neck infection requiring urgent surgical evaluation
