Early is the completion of the CDC's 15 day plan which was announced on March 16th: https://www.whitehouse.gov/wp-content/uploads/2020/03/03.16.... https://www.cdc.gov/coronavirus/2019-ncov/community/15-day-p...

So around March 30th?

I don't know Reuter's opinion of 'too early', but reducing quarantine before the current exponential growth has stopped and before hospitals are not overwhelmed seems like a bad idea.
