Aspergillosis is a condition caused by aspergillus mould. There are several different types of aspergillosis. Most affect the lungs and cause breathing difficulties.
How you get aspergillosis
Aspergillosis is usually caused by inhaling tiny bits of mould. The mould is found in lots of places, including:
- soil, compost and rotting leaves
- plants, trees and crops
- damp buildings
- air conditioning systems
You cannot catch aspergillosis from someone else or from animals.
Aspergillosis is rare in healthy people
You're usually only at risk of aspergillosis if you have:
- a lung condition – such as asthma, cystic fibrosis or chronic obstructive pulmonary disease (COPD)
- a weakened immune system – for example, if you have had an organ transplant or are having chemotherapy
- had tuberculosis (TB) in the past
Symptoms of aspergillosis
Symptoms of aspergillosis include:
- shortness of breath
- a cough – you may cough up blood or lumps of mucus
- wheezing (a whistling sound when breathing)
- a high temperature of 38C or above
- weight loss
If you already have a lung condition, your existing symptoms may get worse.
What happens at your appointment
Your GP will check for an obvious cause of your symptoms, like a chest infection or asthma.
If they're not sure what the problem is, they may refer you to a specialist for tests such as:
- X-rays and scans
- blood tests or tests on a sample of mucus
- allergy tests
- a bronchoscopy – where a thin, flexible tube with a camera at the end is used to look in your lungs
Treatment for aspergillosis depends on the type
Treatment usually helps control the symptoms. If it's not treated or well controlled, there's a risk it could damage your lungs.
|Allergic bronchopulmonary aspergillosis (ABPA) – an allergy to aspergillus mould||steroid tablets and antifungal tablets for a few months (possibly longer)|
|Chronic pulmonary aspergillosis (CPA) – a long-term lung infection||long-term (possibly lifelong) treatment with antifungal tablets|
|Aspergilloma – a ball of mould in the lungs, often linked to CPA||surgery to remove the ball if it's causing symptoms|
|Invasive pulmonary aspergillus (IPA) – a life-threatening infection in people with a weakened immune system||antifungal medicine given directly into a vein in hospital|
You cannot always prevent aspergillosis
It's almost impossible to completely avoid aspergillus mould.
But there are things you can do to reduce your risk of aspergillosis if you have a lung condition or weakened immune system.
