Very high

 

Moderate to severe asthmatics are deemed to be at high risk - use this as your starting point and stratify depending on dose of medication.

 

Very high risk includes those using a combination inhaler including a long-acting bronchodilator at a high daily steroid dose

 

Elevate to next level if smoker/vaper

Around 10% of the population have clinician-diagnosed asthma, and around 10% of those who have diagnosed asthma fall into this 'severe asthma' category.

This means around 1% of the population have severe asthma, and the current suggested fatality rate for COVID-19 is 0.2% for people under age 40. This adds useful perspective to the likely risk from severe asthma, as this is only one of the possible co-morbidities increasing the risk of death in the under 40s.

Asthma

On blue inhaler/salbutamol/Ventolin plus daily steroid inhaler in lower dose than above

 

Daily combination inhaler on dose lower than above
High

Emerging evidence suggests that asthma is not as high a risk as initially thought. These tables may therefore overestimate risk.

Interstitial lung disease and pulmonary fibrosis

MRC breathlessness score 2 and below, none of the above treatments
High  
 Lymphangioleiomyomatosis (LAM) Very high or high Likely to be at least high once a patient has presented clinically, and may well be advised to shield if at an advanced stage or if substantially immunosuppressed.

MRC Dyspnoea Scale 5

too breathless to leave the house, or breathless when dressing/undressing

Very high  

MRC Dyspnoea Scale 4

Stops for breath after walking 100yds or after a few minutes on level ground

Very high  

MRC Dyspnoea Scale 3

Walks slower than most people on the level, stops after a mile or so, or stops after 15 minutes walking at own pace

Very high or High

 

MRC Dyspnoea Scale 2

Short of breath when hurrying on a level or when walking up a slight hill

High or increased

 

MRC Dyspnoea Scale 1

Not troubled by breathlessness except on strenuous exercise

Increased  

Other respiratory infection

Past TB

Increased

https://www.europeanlung.org/en/QA-covid-19 

post-TB lung damage often puts you at a higher risk of picking up chest infections and so you might be at slightly higher risk of having a chest infection if you were infected with COVID-19

Other respiratory infection

Current viral infection

Unclear, may be increased

https://www.europeanlung.org/en/QA-covid-19

individuals can get Covid19 in the presence of other URTI – no data on whether the effect will be increased

Other respiratory infection

Past infection, recovered

Low once well and after 7 days

https://www.europeanlung.org/en/QA-covid-19 

Previous infections do not increase the risk of more severe infections in future unless the previous infections were due to other diseases (such as severe heart or lung conditions, diabetes or conditions or drugs that suppress the immune system)

Sarcoidosis

Stage III or IV

MRC breathlessness score 3 or more

Two or more exacerbations or flare-ups in past year requiring steroids or antibiotics

Regular daily oral steroid

Home oxygen therapy

FVC <80%, TLco <60%

Pulmonary hypertension
