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

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. MUKHERJEE, M., et al, A. 2016.

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. HALPIN, D. M. G., et al. 2020. Do chronic respiratory diseases or their treatment affect the risk of SARS-CoV-2 infection? Lancet Respir Med. |

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 | 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 Currently taking immunosuppresants |
