Sorry to hear that Richard... but don't say I didn't tell you so !
You have no immunity.. don't let anyone near you with a sniffle. Be vigilant that staff are gloving and gowning!
At home... hand sanitizer at each access to your home. DO NOT let anyone past that dispenser without using it... no matter how many times they say "I'm just here for a quick hello". If they're not healthy they don't come in the door...period... that includes family so be sure they have alternative places to stay if they become the slightest bit ill.
If people have dry hand issues there is a moisturizing sanitizer mfg by Gold Bond. We had to bring it up from the USA.. but recently saw it in the Rexall Drug Store in Mount Sinai.
