Strep throat and other sore throat infections share overlapping symptoms, making diagnosis tricky without professional testing. Doctors point to specific red flags that suggest bacterial strep rather than viral causes.
Classic strep throat symptoms include sudden severe throat pain, fever above 101 degrees Fahrenheit, swollen and red tonsils often covered with white or yellow patches, and swollen lymph nodes in the neck. Many patients experience body aches and headache. Notably, strep typically does not cause cough, congestion, or runny nose, which distinguishes it from common cold viruses.
The distinction between strep and COVID-19 matters for treatment. Strep throat causes abrupt onset sore throat and fever, while COVID-19 develops gradually and often includes respiratory symptoms like cough and shortness of breath. COVID-19 patients may lose taste or smell, a symptom rare in strep infections.
Only a rapid strep test or throat culture can confirm strep throat. These tests involve swabbing the back of the throat. The rapid test produces results within minutes, though it occasionally misses cases. A throat culture takes longer but provides definitive diagnosis and is performed when rapid testing is negative but strep remains suspected.
Antibiotic treatment requires confirmed strep diagnosis. Taking antibiotics without testing promotes antibiotic resistance and offers no benefit for viral sore throats. Treatment typically involves penicillin or amoxicillin taken for the full prescribed course, usually 10 days.
Home care alleviates symptoms while waiting for test results or during treatment. Throat lozenges, warm salt water gargles, and over-the-counter pain relievers reduce discomfort. Staying hydrated and resting support recovery.
Untreated strep can progress to complications including rheumatic fever, which damages heart valves, and
