Is Strep Throat Infectious?

Strep throat infection is a bacterial infection that causes inflammation and pain in the throat. This is the common cause of streptococcal bacteria in group A. Strep throat infection can affect children and adults. But it is most commonly seen in children between 5 and 15 age range. Sneezing and coughing can infect an individual person.



Strep throat infection can vary from person to person. Some people may experience mild symptoms such as sore throat, while others may have more severe symptoms such as fever and difficulty in swallowing. Common symptoms of Strep throat infection are:

  • High fever

  • Sore throat (redness in throat with white tatch)

  • Headache

  • Chillily shake

  • Loss of appetite

  • Swollen lymph nodes

  • Difficulty in swallowing

Strep throat symptoms typically show up within five days after you get the bacteria into your body.


Every sore throat is not the result of a strep infection. Other diseases may also cause this symptom. These include colds, sinus infections, post-nasal drainage, and acid reflux. Throat inflammation, which is caused by other medical conditions, often heals itself in a few days, even if it not is treated.


If you are suffering from a long-term sore throat, your doctor will check your throat and see whether there are signs of inflammation or not. Your doctor will also check your neck for lymph nodes and ask for other symptoms. If your doctor suspects strep throat infection she or he can do a quick strep test.


This test determines whether the cause of sore throat is a strep infection or another bacterium / microbe. Your doctor will touch behind your throat with a long cotton swab and take a sample. Then your doctor sends your sample to the lab to search for bacterial symptom.
