Strep throat is a bacterial infection that causes inflammation and pain in the throat. It is caused by a type of bacteria called Streptococcus pyogenes, also known as Group A streptococcus. Strep throat is common among children and teenagers, but it can affect people of all ages.
Some symptoms of strep throat can include:
- Sore throat
- Painful swallowing
- Red and swollen tonsils
- White or yellow spots on the tonsils
- Swollen lymph nodes in the neck
- Fever
- Headache
- Nausea or vomiting
- Fatigue
- Rash
A doctor can diagnose strep throat by taking a throat swab and testing it for the presence of Group A streptococcus bacteria. It is important to get an accurate diagnosis, as strep throat can lead to serious complications if left untreated.
Strep throat is treated with antibiotics, such as penicillin or amoxicillin. It is important to take the full course of antibiotics, even if symptoms improve, to ensure that the infection is fully cleared. Pain relievers, such as acetaminophen or ibuprofen, can help alleviate symptoms such as fever and sore throat.
Strep throat is highly contagious and can be spread through contact with respiratory secretions, such as saliva or mucus. To prevent the spread of strep throat, it is important to wash hands frequently with soap and water, cover the mouth and nose when coughing or sneezing and avoid sharing food or drinks.
If left untreated, strep throat can lead to serious complications, such as rheumatic fever, kidney inflammation and ear infections. It is important to seek medical attention if symptoms of strep throat persist or worsen, or if new symptoms develop.
To prevent the spread of strep throat, it is important to practice good hygiene and stay home from school or work until at least 24 hours after starting antibiotics.
You should change out your toothbrush and sterilize mouth pieces (mouthguards, retainers, etc.) 48 hours after starting treatment to avoid reinfection.
You can visit a UofL Physicians – Primary Care or UofL Health – Urgent Care Plus location if you think you may have strep throat.
