(Throat Infection,Strep,Streptococcal Pharyngitis)
Strep throat is a common bacterial infection, accounting for about 15% of all sore throats that get diagnosed in the doctor's office.
It's called "strep" throat because the bacterium that causes it belongs to the class known as group A streptococcus (GAS). Although strep throat can occur any time during the year, late winter and early spring are considered to be peak seasons for strep throat infections.
Sore throat is one of the leading complaints that bring people to the doctor's office, and the majority of adults with sore throats are treated with antibiotics, though fewer than half of the people given antibiotics actually have bacterial infections. Most of the rest have viral infections that are not affected by antibiotics.
When used appropriately, antibiotics are very helpful in fighting infection. However, antibiotics used inappropriately can be bad for you, killing harmless bacteria that may be keeping dangerous bacteria out of your intestines. It is important to learn about appropriate (and unnecessary) antibiotic use, which includes not pressing a doctor for antibiotics when the doctor says they aren't needed.
Streptococci are everywhere – many people carry it on their skin and throat. They don't always cause disease: that is, they don't always cause strep throat infection. However, streptococci are infectious. They are passed around in the same way as cold viruses, by coughing, sneezing, or getting mucus or saliva on the hand, then touching other people. They are less contagious than a cold virus, however.
Symptoms and Complications
- fever (greater than 38°C or 100.4°F), chills, and sweating
- nausea and vomiting (sometimes)
- sore throat
- swollen tonsils and lymph nodes in the neck
- white patches on the tonsils
- joint pain
- severe abdominal pain
- stiff neck
- sudden high fever
Streptococcal pharyngitis, as strep throat is formally known, causes these symptoms:
Coughing, runny nose, stuffiness, and sneezing aren't associated with strep throat and are usually signs of a viral infection. It's also rare for streptococcus to invade the larynx (voice box), causing hoarseness – this is far more likely with a virus. Of course, it's possible to have both viral and bacterial infections at the same time.
After exposure, it takes about 24 to 72 hours for the bacteria to incubate in the body, or become great enough in number before symptoms are seen.
Before the discovery of antibiotics, strep throat often led to serious complications. The most dangerous of these was rheumatic fever. In rheumatic fever, the immune system inflicts serious damage on the vital heart valves. This can leave a person vulnerable to a certain type of heart problem later in life. Fortunately, this is a very rare occurrence today.
Other possible complications include immune overreaction in the joints (arthritis) or in the kidneys (glomerulonephritis). The bacteria can also travel up tubes that link the throat to the middle ears (the eustachian tubes). This is especially likely in young children, whose ear tubes aren't yet fully developed. This causes otitis media, which is an infection of the middle ear. The bacteria may also get into the lining of the brain and cause meningitis.
All of these complications are extremely rare, except otitis media. A few children develop a chronic pattern of recurring throat and ear infections.
The syndrome known as scarlet fever is a fairly rare, usually mild complication of strep throat, and is essentially nothing more than strep throat accompanied by a temporary red rash. The rash is most prominent on the abdomen and the sides of the chest. Some skin may peel when it subsides.
If complications do appear, they often come 1 to 6 weeks after the strep throat infection. Call a doctor if you see any of these symptoms:
Making the Diagnosis
We've all opened our mouths and said "aaah" at some point. That's a simple test for strep throat. Usually, if bacteria are present, the uvula (the punching-bag-shaped object hanging at the back of the mouth) and the tonsils are red and inflamed and dotted with pus deposits. Another finding may be tiny reddish-blue spots called petechiae on the roof of the mouth.
Even doctors can't always tell a bacterial infection from a viral infection by the symptoms alone. The standard test is a throat swab to gather bacteria from inside the throat, to be sent to a lab or tested in the doctor's office using a special kit. Many doctors' offices, and even some pharmacies, use rapid tests that can provide results in less than 15 minutes.
Treatment and Prevention
- Anyone taking antibiotics should finish the prescription even if symptoms are gone.
- Children with the illness shouldn't go to school until they've been on antibiotics for at least 24 hours.
- Children should be taught to cover their nose and mouth if they cough, for example, by coughing into their sleeve or into a tissue.
- If you're taking antibiotics, consider replacing the "good" bacteria in your digestive tract. You can do this by eating yogurt containing live Lactobacillus acidophilus. It is also available in a pill form. Ask your health care provider if taking Lactobacillus acidophilus is appropriate for you.
- People with strep throat and those around them should wash their hands frequently.
- People with strep throat should discard their old toothbrush and use a new toothbrush after being on antibiotics for 24 hours.
The vast majority of streptococcal throat infections will go away on their own even without treatment, and the chance of rheumatic fever or meningitis is small even if you don't go to the doctor. The main reason to use antibiotics is to prevent these very rare but serious complications; not to treat the throat symptoms. The majority of sore throats do not get seen by a doctor, yet hardly any of these untreated patients develop complications.
You can help manage symptoms such as pain caused by sore throat with over-the-counter products like acetaminophen* or ibuprofen.
The most commonly used antibiotics to treat strep throat are from the penicillin class of antibiotics. They are available by prescription and come as oral tablets, capsules, or liquid suspensions. They are prescribed for a period of 5 to 10 days. Be sure to mention to your doctor if you have allergies to any medications.
Most of the people given oral antibiotics for sore throat don't have bacterial infections, so they can't possibly benefit from these medications. They can, however, be harmed by antibiotics. You shouldn't take antibiotics for a sore throat unless you've had a bacterial infection properly diagnosed or unless otherwise instructed by your doctor. However, if you are treated with antibiotics, finish the course of treatment! This will help to prevent antibiotic resistance.
