When you or your child has a sore throat, it can be hard to tell if it might be something that needs medical intervention, like Strep throat. Strep throat is an infection caused by group A Streptococcus (GAS). When you confirm (by throat swab in the lab) that GAS is present, your child needs 10 days of antibiotics. If the test is negative, it’s unlikely you need any Rx medical treatment! More below:Sore Throat Tonsillitis refers to tonsils that are inflamed. Inflamed tonsils (and even when they have white stuff on them) doesn’t necessarily mean your child needs antibiotics. If enlarged tonsils make it hard to swallow or changes the sounds when your child breaths, they need to see a pediatrician. Pharyngitis refers to an inflamed throat. Most episodes of pharyngitis are caused by infections from viruses. Some are caused by other bacteria that live in the throat that aren’t as problematic as GAS and don’t require antibiotic treatment. Viruses, bacteria, allergens, environmental irritants (such as cigarette smoke), and chronic postnasal drip can all cause a sore throat. Most tonsillitis & pharyngitis will typically resolve on their own without prescription treatment. Try acetaminophen or ibuprofen for pain, throat lozenges, warm beverages, gargling salt water and get lots of rest. In time, sore throats typically improve in a few days. Strep throat is an infection caused by a specific type of bacteria, Streptococcus. Infections from the bacteria can be minor or severe. When your child has Strep throat, their tonsils are usually very inflamed, they likely have a fever and swollen lymph nodes in the front of the neck, a BAD sore throat, and sometimes a headache. Many children complain of lots of pain with swallowing. Strep throat symptoms typically come in isolation from other “cold symptoms.” With typical strep, most children do not have cough, runny nose or hoarseness (changes in your voice that makes it sound breathy, raspy, or strained). No one can diagnose strep throat just by looking at your throat. Instead, healthcare professionals use two tests to see if group A Strep bacteria are causing a sore throat. A “rapid strep test” involves swabbing your throat and gives results quickly, usually in about 15-20 minutes. The test is accurate about 95% of the time meaning only 1 in 20 people (5%) who have a negative test actually may have the infection. If the rapid test is positive, your doctor or provider will prescribe antibiotics. If the test is negative, your healthcare professional may likely send the swab for a full throat culture (to catch the 5% that falsely didn’t show an infection). A throat culture involves sending a throat swab to a lab for 1-2 days to see if bacteria grow from the sample. If it turns positive, then your child should be treated with an antibiotic for 10 days.
Great information from the American Academy of Pediatrics on the differences between a sore throat and strep.
