COVID-19 UPDATES (5/16/22)

Hello Kolvita Family,

Well, as much as we had hoped the number of positive Covid cases wouldn't rise again, we are in the middle of that trend.  In fact, at Kolvita we have seen a small spike in cases amongst our patients.  The good news is that we have kept in contact with our ICU specialists and hospitalists---and they have told us that, locally, numbers or severe cases and ICU admissions HAVE NOT increased significantly.  Hopefully this is a good sign that the vaccines, boosters, previous infections and all other safety measures are finally having the affect we want!
