Hi
I don't know if this helps at all but I heard a news report saying that flu had peaked and cases were now on the decline. I don't know about norovirus but I do know that before Christmas it was said that it would peak in January or February. The good thing ( if there is a good thing) about norovirus as opposed to flu is that it is easier to protect yourself against it with good hand hygiene. With colds and flu people seem to try to play the hero and struggle on going to work which makes life much harder for those of us that are trying to avoid it.
The end is in sight lol.
