When sinusitis is caused by a viral infection (like a cold or flu), the same germs that cause it can spread from one person to another, usually through coughing and sneezing.1-2

Sinusitis can also be caused by bacteria, which grows in the sinuses when extra mucus builds up.People with bacterial sinusitis should avoid direct contact with others, to prevent the spread of germs.2

It’s important to protect yourself and others against infection by practising good health and hygiene habits.3

Healthy habits to avoid spreading germs

Cold or flu viruses are usually spread from person to person in tiny droplets produced when someone with the virus coughs, sneezes or talks.4 People who breathe in these droplets can catch the virus.4

Did you know? A person with flu can spread it to people standing up to 1.8 m
(6 feet) away from them!4


To avoid catching or passing on a virus, follow common sense and good hygiene:3

  • Always cover your mouth and nose when you cough or sneeze.
  • Wash your hands regularly with soap and water, to protect yourself from germs.
  • Use sanitiser to clean your hands if soap and water aren’t available.
  • Avoid touching your mouth, nose or eyes with unwashed hands.
  • If you get a cold or flu, stay home from work or school to avoid spreading germs.
  • People who are sick should avoid close contact with others.

A virus can also spread to someone if they touch a surface or object that has germs on it and then touch their nose, mouth or eyes without washing their hands.4

Is sinus congestion contagious?

Sinus congestion isn’t an infection or a virus, it’s a symptom.5,6 Congestion is a "blocked", full or heavy feeling caused by inflammation, and it can lead to a build-up of extra mucus in the sinuses and nasal passages when you have a cold, the flu or allergies.5,6 So, congestion itself isn’t contagious, but some of the causes of congestion (like a cold or flu virus) are contagious.1
