Here's an informative thread from Zeynep, who you should be following for sound advice and useful information regarding the virus situation.
Sunshine and fresh air is very important for immunity and overall well-being. Ordering everyone to remain holed up in their home for months on end is counter-productive.
Do go outside, it's good for you. But take care to avoid close contact, and wear a mask if you need to interact with anyone. (Unless, of course, you're sick or under quarantine orders, then just tough it out for two weeks or until you get the all clear.)
