Not for if under strict quarantine but I found this information useful regarding how the virus is spread for if, as a family, we find ourselves in the position of experiencing the symptoms but can't get tested and are self caring and isolating at home.

Catching it is not that easy (if we are careful) and we can kill it quite easily (provided we try). Frequent, careful hand washing, as we now all know, is the most effective way to stop the virus being transmitted, while a solution of ethanol, a solution of hydrogen peroxide or a solution of bleach will disinfect surfaces. To be considered at high risk of catching the coronavirus you need to live with, or have direct physical contact with, someone infected, be coughed or sneezed on by them (or pick up a used tissue), or be in face-to-face contact, within two metres, for more than 15 minutes. We’re not talking about passing someone in the street.
So I'd still take the children out in our small front and back gardens, they'd be far enough away from neighbours and passers by. Drive to the shops, practise good hand and tissue hygiene, if not stopping to chat to anyone and going through self serve wouldn't be in prolonged contact.
Within the house we can't isolate from each other as a family, the six of us live in our three bed end terrace with one bathroom, children share bedrooms. So accept if one of us gets it we all will to some degree as with all viruses we pick up (a lot of which come home from school...).
