When you have a sinus infections contagious, your nasal and facial cavities become swollen and produce excess mucous. These conditions make it difficult for the sinuses to drain naturally, which is why they become infected so easily. If you have a brother, sister, or parent who has been diagnosed with chronic recurrent rhinosinusitis (CRS), you might wonder if you’re at risk of contracting this disease as well.

The good news is that no one catches CRS from someone else. Rather, it’s an inherited condition with genetic markers that are passed down from parents to their offspring. Read on to find out more about whether or not you can catch a sinus infection from someone else and what precautions you should take if you know that members of your family are prone to developing CRS.

What’s the difference between a cold and a sinus infections contagious?

Cold and flu are both viral infections that affect the upper respiratory tract. Cold is caused by rhinoviruses, while flu is caused by influenza viruses. Both viruses cause nasal congestion, sneezing, coughing, and a general low-level feeling of being unwell. Sinuses, on the other hand, are air-filled cavities located in the bones around the nose.

They are connected to the nasal cavity via vertical holes called the paranasal sinuses, which are lined with mucous membranes. When these sinuses get infected, they fill with fluid and become swollen, which causes pain and discomfort.

A sinus infections contagious can occur if you breathe in a virus that has been expelled from another person’s body, such as through sneezing. Once the virus enters your nose, it travels down the paranasal sinuses, where it multiplies and causes damage to the surrounding tissues. Sinus infections contagious can also be caused by bacteria, especially if the immune system of the infected person is compromised in any way.

How you can catch a sinus infections contagious from someone else

We’ve established that you can catch a cold or flu from someone else, and that’s also true of a sinus infection. What you need to keep in mind is that a sinus infections contagious is a bacterial infection, meaning that you can’t just “catch” it as you would a cold or flu.

The best way to explain how you can catch a sinus infection from someone else is to use an example. Say you’re visiting your grandparents and your grandpa has a sinus infection. He might not feel like himself, so he might not cover his mouth when he sneezes, which means that the bacteria from his infection will travel through the air and into your nose.

Can you be sure that you won’t get a sinus infection from someone else?

Not entirely. While there are certain ways that you can minimize your chances of catching a sinus infection, there’s no guarantee that you won’t get one. If you have chronic rhinosinusitis and your symptoms are under control, there’s a chance that you could infect others.

Since people with CRS produce large amounts of mucous, they’re at risk of contaminating the environment with their own contaminants when they blow their nose. It’s also important to note that people with CRS are contagious even when they aren’t experiencing any symptoms. This means that you could be spreading your infection even when you don’t notice anything unusual about your health.
