Those with elderly relatives please BEG them to stay safe, to keep away from crowds, busy environments, planes, anything with people, for a good while, until this first wave passes and we have a hold on the situation
Perhaps they can be left to make their own decisions. A friend of my mother's who is 97 nearly 98, said she'll carry on going out and if she gets it she gets it. She'd rather die now than end up in a home.
