Sinus infections are not contagious in the same way that the common cold is. Most sinus infections are caused by bacteria, and bacteria cannot be spread through the air like viruses. However, the viruses that cause the common cold can also cause sinus infections, and these viruses can be spread through the air.
So, while you cannot get a sinus infection directly from someone else, you can get the virus that causes a sinus infection from someone else. Once you have the virus, it can travel to your sinuses and cause an infection.
Here are some tips to help prevent the spread of viruses that can cause sinus infections:
- Wash your hands frequently with soap and water.
- Avoid touching your eyes, nose, and mouth.
- Stay home when you are sick.
- Cover your mouth and nose when you cough or sneeze.
- Clean and disinfect frequently touched surfaces.
If you think you may have a sinus infection, see your doctor. They can diagnose the infection and prescribe the appropriate treatment.
