I think I found something important.    But I will let you be the judge.  And I would love to hear from any epidemiologists that read my blog. The number of COVID cases is increasing in Oregon and Washington, while most of the other states are seeing declining or stable COVID caseloads.  The increases are sufficiently worrying that Governor Inslee may reverse the opening of the State.

Extraordinarily serious decisions are being made without key information:  how many individuals have active infections?  How many have had the virus and now have immunity?  What percentage of infected individuals have few or no symptoms?  Who is currently infected and needs to be quarantined?  Is the current reduction in cases in Washington and elsewhere mainly the result of social distancing or the herd immunity of an increasing number of individuals that have had the virus? For all these questions, we do not know the answer.  Our best medical scientists and epidemiologists, including a highly respected group at the University of Washington, are making projections of the future progressio
