Those numbers probably aren't knowable at this time. Over the last day I've seen stories that claim person to person transmission is twice as likely as previously thought but transmission via an object is much less likely than previously thought. Wouldn't be surprise if tomorrow there were stories claiming the exact opposite. It feels like we're both drowning and dying of thirst when it comes to information. But this crisis has not really been going on for very long. We have become so accustomed to getting information instantly that it's going to feel like an eternity before we get data that we are confident in strongly.
