Are You Contagious? What You Need to Know about Bacterial Sinus Infections

April 2, 2025
5 Minute Read

We all know the dread that erupts when you find out someone at school or the office has come down with a case of something super contagious, like the flu or strep. It feels like no matter what you do, you’ll be the next case.

With bacterial sinus infections, many patients don’t actually know whether this particular condition is spreadable or not. These types of infections aren’t that uncommon, and usually aren’t hard to treat, However, knowing what you do and don’t need to do to avoid getting an infection is crucial!  The WOW Healing Care blog is back to make sure you have all the information you need.

What Is a Bacterial Sinus Infection?

A sinus infection, also known as sinusitis, occurs when the tissue lining the sinuses becomes inflamed. Sinus infections can be caused by viruses, bacteria, or even fungi. While viral sinus infections are more common, bacterial sinus infections are typically a little more severe and may require antibiotics to clear up.

Symptoms of a Bacterial Sinus Infection

Symptoms of a bacterial sinus infection often include:

  • Thick, discolored nasal discharge (often yellow or green)
  • Facial pain or pressure, especially around the eyes, forehead, and cheeks
  • Nasal congestion
  • Reduced or lost sense of smell
  • Cough or throat irritation
  • Fatigue
  • Fever (in some cases)

These symptoms can overlap with viral sinus infections, but bacterial infections tend to last longer and may worsen after an initial improvement.

Are Bacterial Sinus Infections Contagious?

The short answer to the question “are bacterial sinus infections contagious?” is generally no. Bacterial sinus infections are not considered contagious in the same way that viral infections, like the common cold, are.

Wait a Minute. Why not?

The bacteria that cause a sinus infection typically originate from within your own body. When the sinuses become blocked, bacteria that normally live harmlessly in the nasal passages can multiply and cause an infection. Since this process involves bacteria that are already present in your body, you generally cannot “catch” a bacterial sinus infection from someone else..

Having said this, it’s important to note that while bacterial sinus infections are not contagious, the viral infections that can lead to sinusitis are. For example, if someone with a cold sneezes or coughs near you, you could catch the cold virus. In some cases, a viral infection can develop into a bacterial sinus infection, though that doesn’t happen super frequently.

Preventing Sinus Infections and Promoting Wellness

Although bacterial sinus infections aren’t contagious, it’s still crucial to maintain good health practices to reduce your risk of developing any sinus infection. Dr. Edwards favorite health advice is always preventative! Here are some wellness tips for preventing sinus infections and managing symptoms:

  1. Practice Good Hygiene
  • Wash your hands regularly: Frequent handwashing is one of the most effective ways to prevent the spread of viruses and bacteria.
  • Avoid touching your face: This can prevent germs on your hands from entering your body through your nose, mouth, or eyes.
  • Stay away from sick individuals: If someone around you has a cold or the flu, try to minimize contact to avoid catching their virus.

  1. Keep Your Sinuses Clear
  • Use a saline nasal spray: Saline sprays can help keep your nasal passages moist and clear of irritants.
  • Try a humidifier: Keeping the air in your home moist can help prevent your nasal passages from drying out. Drier nasal passages are more prone to infection, so the humidifier can mitigate dryness that naturally occurs with weather changes.
  • Stay hydrated: Drinking plenty of water helps keep the mucus in your sinuses thin, and thin mucus drains more easily.
  1. Boost Your Immune System
  • Eat a balanced diet: Include plenty of fruits, vegetables, and whole grains to support a healthy immune system.
  • Get regular exercise: Physical activity can help strengthen your immune system and reduce any inflammation you have.
  • Manage stress: Chronic stress can weaken your immune system, making you more susceptible to infections. Practice stress-reducing activities like meditation, yoga, or deep breathing, or just engage in things you love for a great endorphin release!
  1. Seek Medical Attention When Necessary
  • Consult with a healthcare provider: If you suspect you have a sinus infection, it’s a great idea to see your provider. They can determine whether antibiotics or other treatments are necessary.
  • Follow prescribed treatments: If antibiotics are prescribed, be sure to take the full course as directed, even if you start feeling better. This ensures that the infection is fully cleared and reduces your risk of antibiotic resistance.

When You Do Have a Bacterial Infection, Do…

Here are some tips to best manage your symptoms when you have a bacterial sinus infection:

  1. Understand When Antibiotics Are Necessary

Remember, antibiotics cannot treat viral infections. Overusing antibiotics can lead to antibiotic resistance (this is not ideal, so only use them when prescribed by your provider!). But antibiotics do effectively fight off bacterial sinus infections.

  1. Give Your Body the Nutrients It Needs

Incorporate probiotics like yogurt, kefir, or supplements to help maintain a healthy gut flora, especially if you’re taking antibiotics. Also make sure you’re eating a healthy diet low in processed foods and high in whole foods. A balanced diet can boost your immune system!

  1. R&R

Make sure you get plenty of sleep—your body needs lots of rest to effectively fight off an infection. Drinking water will also help your body flush out toxins (bonus points for adding electrolytes to your water!).  

        4. Stay Informed and Proactive

Stay proactive with your health by scheduling regular check-ups with your healthcare provider, especially if you’re prone to sinus infections. Make sure you understand the difference between viral and bacterial infections and seek appropriate care accordingly.
