Overview

Aspergillosis is a condition caused by aspergillus mould. There are several different types of aspergillosis – most affect the lungs and cause breathing difficulties.

Title
Aspergillosis

Types
  1. Allergic bronchopulmonary aspergillosis (ABPA) – an allergy to aspergillus mould.
  2. Chronic pulmonary aspergillosis (CPA) – a long-term lung infection.
  3. Aspergilloma – a ball of mould in the lungs, often linked to CPA.
  4. Invasive pulmonary aspergillus (IPA) – a life-threatening infection in people with a weakened immune system.
Symptoms

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.

Causes

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
  • Dust
  • Damp buildings
  • Air conditioning systems

You can't catch aspergillosis from someone else or from animals.

Most people who breathe in the mould don't get ill

Diagnosis

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

Treatment usually helps control the symptoms. If it isn't 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

 

Risks

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've had an organ transplant or are having chemotherapy
  • Had tuberculosis (TB) in the past
Self-help

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.

Do

  • Try to avoid places where aspergillus mould is often found, such as compost heaps and piles of dead leaves
  • Close your windows if there's construction work or digging outside
  • Wear a face mask in dusty places
  • Consider using an air purifier at home – devices filters are best

Don't

  • Dry your laundry in your bedroom or living areas, if possible – ideally dry it outside or in a tumble dryer
