Strep throat is a highly contagious infection that spreads through direct contact or respiratory droplets when an infected person sneezes or coughs near you. But it is curable and preventable if you follow simple prevention steps. However, if you leave it untreated it not only increases the risk of spread but also leads to serious illnesses. So, always take treatment whenever you notice the symptoms of strep throat and save others from this infection. Learn how strep throat spreads in this article. Log on to for a consultation.

Is strep throat contagious?

Yes, strep throat is very contagious, because it can pass from person to person through close contact especially when the infected person coughs, sneezes, or makes direct contact. You can have a strep throat infection when:

  • You breathe the infected droplets from the air.
  • Touch something that these droplets land on, such as a table, or doorknob, and rub your mouth, eyes, and nose.
  • Share personal items with the infected person such as a fork, towel, glass, nail cutters, and toothbrush.
  • Kiss a person who is infected.
  • If you touch the sores of the person who is infected or encounter fluid from the sores.

When you get an infection, it takes 2 to 5 days to show symptoms after you get exposed to the bacteria. In some cases, infected people don’t have symptoms or get sick, however, they are not as highly contagious as the ones with symptoms. You will stay contagious for a month if not treated. People who take antibiotics within 24 hours after the infection stop being contagious.

High-risk population

Some people are more vulnerable to infections.

Anyone can develop strep throat, but certain conditions can increase the likelihood of contracting this common infection, like:


Children are more likely than adults to get strep throat. It is most common in youngsters aged 5 to 15. It is quite unusual in children under the age of three.


Adults who are more likely to get strep throat include:

  • Parents with children at school
  • Adults who frequently interact with children


The most common risk factor for sickness is close contact with another person who has strep throat. For example, if someone has strep throat, the bacteria are commonly passed on to other members of the household.

Infectious diseases tend to spread among big groups of people. Crowded environments can increase the likelihood of contracting group A strep. Among these options are:

  • Schools
  • Nursery facilities
  • Military training grounds

Strep throat during pregnancy

If you suspect you have strep throat during your pregnancy, consult your doctor as soon as possible to discuss treatment options. Your doctor may prescribe antibiotics and closely monitor your treatment regimen. Improve your understanding of how to manage strep throat while pregnant.

Group A streptococcus, the bacteria that causes strep throat, is not the same as group B streptococcus, which is found around the vagina or rectum. While group B streptococcus can be transferred to a baby at birth, it is not the same bacteria that causes strep throat.

Strep throat complications

If neglected, strep throat can lead to significant consequences:

  • Bacteremia (sometimes known as “blood poisoning”) occurs when germs enter the bloodstream.
  • The inflammation of the membranes that surround the brain and spinal cord (meningitis).
  • Pneumonia (caused when the bacteria that cause strep throat enter the lungs).
  • Peritonsillar abscess (a pus-filled abscess that occurs behind the tonsils).
  • Rheumatic fever (an inflammatory condition that affects the joints, heart, and skin).
  • Post-streptococcal reactive arthritis (a type of inflammatory arthritis that affects more than one joint).
  • Poststreptococcal glomerulonephritis (kidney inflammation).
  • PANDAS is a pediatrics autoimmune neuropsychiatric illness related to streptococci that causes rapid changes in a child’s mobility, personality, or behavior following a strep bacterial infection.
  • Streptococcal toxic shock syndrome is a rare but devastating bacterial illness.
