I just want to send a BIG round of applause for the outstanding work you done thus far in getting enrolled HCWs to return for follow-up and in recruiting new enrollees during M12. I know this has not been easy but, with the exception of a couple sites, thus far your numbers are excellent. I realize that where participation has been less than optimal, it likely represents some unique challenges at those sites. When the dust clears, I would like to have some time to discuss the barriers encountered and possible solutions so that we can be optimally prepared for the next round of testing as well as maintaining momentum for the remaining study activities.
