Before we answer the question whether sinus infections are contagious or not, its imperative we look at what a sinus infection really is. Technically, a sinus infection, also known as sinusitis is not an infection by itself but an inflammation or swelling of tissues that line the sinuses.
Such swelling or inflammation happens when fluid (mucus) fills and blocks the sinuses. Viral infections, such as the common cold can block sinuses and cause them to swell up. Secondary bacterial and fungal infections can cause the swelling as well.
Can You Transmit a Sinus Infection to Others?
If the cause of your sinusitis is a viral infection such as the common cold (in most cases it is), then it’s possible that you may pass the virus to another person. The virus will most likely cause cold to the other person, but not necessarily a sinus infection.
What about a Bacterial Sinus Infection?
According to medical practitioners, sinus infection in most people starts as viral infection then progresses to a bacterial infection after seven to ten days. Bearing in mind that the bacteria causing the infection stay in the sinuses, it’s highly unlikely that the infection can be transmitted from one person to the other.
Which are the Symptoms to Look Out for?
Common sinusitis symptoms include;
· Sore throat
· Mucus drenching the throat behind the nose
· Pain across the cheekbone, inner corner of one or both eyes and below one side of the nose
· Sinus headaches
· Ear pain and foul breath
So, are sinus infections contagious? From the above explanation, the answer is a definite no. Even the infections which may be prompted by nasal tumors, allergies or other conditions such as fibrosis are not contagious at all. Most sinus infections require no treatment. However, should you experience the highlighted symptoms for more than a week, don’t hesitate to see a doctor for further medical attention.
