Please read this most recent article by Asaf Bitton at Ariadne Labs here in Boston. He offers an informed opinion in a time of uncertainty. I’d rather follow his advice and hope that it is not necessary than not follow it and discover he was right.  Excerpt:

No kid playdates, parties, sleepovers, or families/friends visiting each other’s houses and apartments

This sounds extreme because it is. We are trying to create distance between family units and between individuals. It may be particularly uncomfortable for families with small children, kids with differential abilities or challenges, and for kids who simply love to play with their friends. But even if you choose only one friend to have over, you are creating new links and possibilities for the type of transmission that all of our school/work/public event closures are trying to prevent. The symptoms of coronavirus take four to five days to manifest themselves. Someone who comes over looking well can transmit the virus. Sharing food is particularly risky — I definitely do not recommend that people do so outside of their family.

We have already taken extreme social measures to address this serious disease — let’s not actively co-opt our efforts by having high levels of social interaction at people’s houses instead of at schools or workplaces. Again — the wisdom of early and aggressive social distancing is that it can flatten the curve, give our health system a chance to not be overwhelmed, and eventually may reduce the length and need for longer periods of extreme social distancing later (see what has transpired in Italy and Wuhan). We need to all do our part during these times, even if it means some discomfort for a while.
