The list of pre-existing conditions for "social distancing measures" for those under 70 is somewhat larger than the media are reporting.

We are advising those who are at increased risk of severe illness from coronavirus (COVID-19) to be particularly stringent in following social distancing measures.

This group includes those who are:

• aged 70 or older (regardless of medical conditions)
• under 70 with an underlying health condition listed below (ie anyone instructed to get a flu jab as an adult each year on medical grounds):
  • chronic (long-term) respiratory diseases, such as asthma, chronic obstructive pulmonary disease (COPD), emphysema or bronchitis
  • chronic heart disease, such as heart failure
  • chronic kidney disease
  • chronic liver disease, such as hepatitis
  • chronic neurological conditions, such as Parkinson’s disease, motor neurone disease, multiple sclerosis (MS), a learning disability or cerebral palsy
  • diabetes
  • problems with your spleen – for example, sickle cell disease or if you have had your spleen removed
  • a weakened immune system as the result of conditions such as HIV and AIDS, or medicines such as steroid tablets or chemotherapy
  • being seriously overweight (a BMI of 40 or above)
• those who are pregnant

At least there isn't the French decree where you have to self-issue a "street pass" in order to go outside.
