Strep throat is a common bacterial infection that primarily affects the throat and tonsils. It’s caused by the bacterium Group A Streptococcus (GAS). Understanding the various aspects of strep throat can help in recognizing its symptoms, ensuring timely diagnosis, and adopting effective treatment and prevention strategies.
Causes
- Bacterial Infection: Strep throat is caused by the Group A Streptococcus bacteria. Unlike most sore throats, which are viral, this is a bacterial infection.1211
- Transmission: The bacteria are highly contagious and spread through respiratory droplets from coughing, sneezing, or close contact with an infected person.1216
Symptoms
- Common Symptoms: These include sore throat, pain when swallowing, fever, red and swollen tonsils, sometimes with white patches or streaks of pus, and swollen lymph nodes in the neck.12
- Other Symptoms: Headache, stomach pain, nausea, vomiting, and rash (scarlet fever) are also common, especially in children.1216
Diagnosis
- Physical Exam: A healthcare provider will look for signs of strep throat during a physical examination.3
- Rapid Antigen Test: This test can quickly detect strep bacteria from a throat swab.37
- Throat Culture: If the rapid test is negative but strep throat is still suspected, a throat culture may be done to confirm the diagnosis.37
Treatment
- Antibiotics: Penicillin or amoxicillin is commonly prescribed to treat strep throat. It’s crucial to complete the full course of antibiotics to prevent complications.34
- Symptom Relief: Over-the-counter pain relievers like ibuprofen or acetaminophen can help relieve throat pain and reduce fever. Home remedies such as gargling with salt water and staying hydrated are also beneficial.45
Prevention
- Hygiene Practices: Regular handwashing, not sharing personal items like utensils, and covering the mouth when coughing or sneezing can help prevent the spread of strep bacteria.258
- Isolation: Infected individuals should stay home from work or school until they have been on antibiotics for at least 24 hours to reduce the risk of spreading the infection.58
Complications
- Rheumatic Fever: Untreated strep throat can lead to rheumatic fever, a serious condition that can affect the heart, joints, nervous system, and skin.212
- Poststreptococcal Glomerulonephritis: This is a kidney disease that can occur after a strep infection.2
- Scarlet Fever: Characterized by a red rash, this can occur in some cases of strep throat.216
Risk Factors
- Age: Strep throat is most common in children aged 5 to 15 years but can affect people of all ages.211
- Close Contact: Being in close contact with someone who has strep throat increases the risk of getting infected.211
