My friend, healthy 38 year old man, has had a fever of over 40 degrees since Sunday and very sick but could not be admitted to hospital because temperature was not at 41. Wednesday morning was struggling to breathe - his wife called an ambulance - it took 5 hours to get to him. Central London. The paramedics said is likely covid but because his oxygen was ok they still wouldn't take him to hospital. He nearly died last night - the ambulance finally took him to hospital early this morning and he is now in ICU under general anaesthetic hooked up to machines and fighting for his life. This is a healthy young man. Please please isolate - this thing is very real and randomly lethal.
