That the Seattle doctor thought that the Wuhan statistics 80% mildly ill, 14% hospital-ill, 6-8% critically ill were generally on the mark, suggests to me that she is working in an area with a lower than average age. I understand that the average age in Seattle is 35 and I’d assume that there were districts within Seattle filled mainly with professionals who are not in close regular contact with their parents.
The average age in Madrid is rather higher than in both Seattle and Wuhan, and close links with the elderly are generally maintained (grandparents are a vital part of Spain’s childcare arrangements). Same is true in Italy.
Knowing this, the emergence of data from Madrid showing that the statistics have been 60% mildly ill, 30% Hospital-ill and 10% critically ill shows that the experience of Seattle may not be replicated in other cities, towns and regions across America. Particularly not once ICUs have been filled.

Testing has been performed widely (even if not exhaustively) throughout the community in Madrid, so the data isn’t terribly skewed towards the demographic most likely to succumb to complications. The testing protocols changed today, so this will no longer apply, but it did hold until earlier today.
