Are sinus infections contagious, and when is medical treatment required in Europe?

Sinus infections explained: viral vs bacterial sinusitis, transmission risk, symptom duration, and prescribing criteria.

In this episode, we clarify whether sinus infections can spread from person to person and how doctors distinguish contagious viral illness from non-contagious inflammation.

You’ll learn:

• The difference between viral sinusitis and bacterial sinus infection

• Why viral upper respiratory infections are contagious

• Why bacterial sinusitis itself is usually not directly contagious

• Typical symptoms: facial pain, nasal congestion, thick discharge, reduced smell

• When symptoms lasting more than 10 days may suggest bacterial infection

• Red flag signs such as high fever, swelling around the eyes, or severe headache

• Situations where antibiotic requests may be declined if criteria are not met

We explain how doctors assess symptom duration, fever pattern, facial tenderness, discharge colour, and complication risk during an online consultation in the EU. Most sinus infections are viral and improve without antibiotics.

This episode reflects the clinical standards used by Mobi Doctor, where ENT-related consultations are reviewed by a registered physician in line with EU prescribing guidance.
