Worried your sore throat may be strep?


Many things can cause that unpleasant, scratchy, and sometimes painful condition known as a sore throat. Viruses, bacteria, allergens, environmental irritants (such as cigarette smoke), and chronic postnasal drip can all cause a sore throat. While many sore throats will get better without treatment, some throat infections—including strep throat—may need antibiotic treatment.

How You Get Strep Throat

Strep throat is an infection in the throat and tonsils caused by group A Streptococcusbacteria (called "group A strep"). Group A strep bacteria can also live in a person's nose and throat without causing illness. The bacteria are spread through contact with droplets after an infected person coughs or sneezes. If you touch your mouth, nose, or eyes after touching something that has these droplets on it, you may become ill. If you drink from the same glass or eat from the same plate as a sick person, you could also become ill. It is also possible to get strep throat from touching sores on the skin caused by group A strep.

A fever is a common symptom of strep throat.

Common Symptoms of Strep Throat

The most common symptoms of strep throat include:

  • Sore throat, usually starts quickly and can cause pain when swallowing
  • A fever
  • Swollen lymph nodes in the front of the neck

Other symptoms may include headache, stomach pain, nausea, or vomiting. Someone with strep throat may also have a rash known as scarlet fever (also called scarlatina).

Cough, runny nose, hoarseness (changes in your voice that makes it sound breathy, raspy, or strained), and conjunctivitis (also called pink eye) are not symptoms of strep throat and suggest that a virus is the cause of the illness.

A Simple Test Gives Fast Results

Healthcare professionals can test for strep by swabbing the throat to quickly see if group A strep bacteria are causing a sore throat. A strep test is needed to tell if you have strep throat; just looking at your throat is not enough to make a diagnosis . If the test is positive, your healthcare professional can prescribe antibiotics (medicine that kills bacteria in the body). If the rapid strep test is negative, but your healthcare professional still strongly suspects strep throat, then they can take a throat culture swab to test for the bacteria, but those results will take a little longer to come back.
