Our biggest concern is that we don't want to see this at other assisted-living facilities.

It likely was brought in from outside, because it is common in the community. But we will never know for sure.

We are recommending that ill persons stay in their rooms.

They wash their hands. And if they handle patients, they wear gloves.

Almost all of the cases have been in the assisted-living wing.

We ask facilities to notify us if 10 percent of their population is affected, or if there is some other unusual situation.

I anticipate there will be more illnesses.

This is normal. By the age of 60, 60 percent of us have had it at some time in our life.

That can take up to a week. It won't be definitive until then.
