Spread through respiratory secretions
Strep throat is spread through contact with respiratory secretions from an infected person. This can happen when someone coughs, sneezes, or talks. Respiratory secretions are tiny droplets of fluid that contain the bacteria that cause strep throat. When an infected person coughs or sneezes, these droplets can be sprayed into the air, where they can be inhaled by someone else. Strep throat can also be spread by sharing food or drinks with an infected person, or by touching something that has been contaminated with the bacteria and then touching your mouth, nose, or eyes.
Strep throat is most contagious during the first few days of illness. However, a person can remain contagious for up to 2 weeks, even if they are no longer showing symptoms. This is why it is important to stay home from school or work if you have strep throat, and to take antibiotics exactly as prescribed by your doctor.
There are a number of things you can do to help prevent the spread of strep throat:
- Cover your mouth and nose when you cough or sneeze.
- Wash your hands frequently with soap and water.
- Avoid sharing food or drinks with others.
- Clean and disinfect surfaces that may have been contaminated with respiratory secretions.
- Stay home from school or work if you have strep throat.
By following these simple steps, you can help to prevent the spread of strep throat and protect yourself and others from infection.
