Genuine question. Googling has not helped.

I and my family have been in self isolation for over a week now. No one has come in, no one has left the house. So there is no human contact.

Once a day we pick up groceries from outside. We leave the bag hanging outside the house for a day before opening and using it, discarding the outer bag. The contents inside, if vegetables/fruits, are thoroughly washed before use. Hands are washed.

Q1: What is the real risk of us contracting the coronavirus from the surface of these packages? I know the risk is non-zero, but like, in percentage terms, how many COVID-19 cases are being detected without direct contact with a COVID-19 patient?

Q2: Can I step out, early morning at 5am when there is no one else outside, and take a walk? The AQI is good, the weather is decent, and I am turning into a pumpkin. What is the risk of contracting the infection from a walk in the open air. I will maintain over 2 meters distance from all humans.

I ask because, by the end of this week, we would have been in isolation for two weeks. So we would know for sure that there was no COVID-19 within my family. But outside, things are bad, and the lockdown will only extend beyond 31 March. A morning walk outside for me and the kids, and more packages/things coming in from outside, will improve the quality of our lives.
