Sinus Infection Contagious? Yes and No. Read Why

Sinuses are air passages located behind the nose, below the eyes and on the cheekbones. Sinus infections can be attributed to colds and allergies. 

When mucus starts to form on the lining of the sinus, bacteria starts to build up and would eventually cause infection. When infected, it can cause headaches and pain on the part of cheek, eyes or the upper teeth.


Sinus Infection Without Congestion

Sinusitis infection without congestion can happen when there is just a minimal amount of mucus allowing the passage

of air. It can also be possible in the absence of polyps that cause blocking of the air passage. Polyps are swollen skin that appears like grapes and causes blocking of the air and sometimes it can also block the part of the nose responsible for smelling.

What Sinus Infection is Contagious?

Before answering this question, let’s try to discuss the two types of sinusitis infection and try to differentiate it from each other. Sinus infection can be categorized as Viral and Bacterial.

Viruses are contagious.

It can transfer to one person to another during its active point. It may be easily transferred but how it affects the next person is variable. If the person has a stable and unshakeable immune system, he will surely not be affected. Remember that colds can be transferred from one person to another during cold seasons. The immune system can also be paralyzed when it is unusually cold.

The possibility of catching colds and developing cough is high during winter. Given the fact that a cold season can contribute more to the risk of being sick easily, the infection can also build faster during this time.

Bacterial sinus infection is not contagious because, unlike viruses, bacteria can be contained. It cannot be transferred by air.


Basic Prevention Measures Against Sinus Infection and Colds

dangerSome people might be wondering if they can catch sinusitis infections like colds. The answer to this is variable. Again, it all boils down to the status of your immune system.

Sinusitis infections often follow a cold when not taken cared of immediately.

Colds can weaken your immune system. If the person has a weak immune system, it is remarkably easy for bacteria and viruses to penetrate. Most of the time this infection is a result of one’s diet. Fried and starchy foods can cause infection.


If a person wants to stay away from any types of sickness, he has to be healthy. Observing a strictly healthy diet is extremely beneficial. To build your defenses from colds, cough and other allergies that can lead to sinusitis infection, he has to eat foods rich in vitamin A. Avoid too many carbohydrates and dairy products.

Eating a small amount of meat especially when fried will also lessen the possibility of having sinus infections. Water therapy is also the best solution to wash out bacteria and mucus on the throat when cold is starting to form.


Doctors always say that prevention is better than cure. Now, the person is already aware of the things that cause sinus infection, check your diet and start changing it to a more conscious and healthier one.

Always bring a hand sanitizer and make it a habit to wash your hands regularly. This way he can be sure that he is eliminating all sorts of sickness causing germs and bacteria.

Sinusitis is particularly common and is not serious, but he should not take it for granted. Remember that deadly illnesses sometimes start from a simple complication until it becomes a real threat.

      I have the same problem & have suffered for years. My allergist turned me on to Neil Med extra strength sinus rinse, using the spray bottle twice a day and it works so well. Give it a try…I’m sure you will be amazed. In addition to that, I take an antihistamine (Xyzal) daily & use Flonase steroid spray twice a day, after my sinus rinse. My sinuses are so much better!!
