Looking through the bbc website I found a story about Eyam, in Derbyshire which interested me, I'd forgotten about this until seeing the story, and if you get chance when this is all over have a ride up there and a look around the village.
If you haven't heard about it, look it up, you may find similarities to today.
Basically at the time of the great plague - around the 14C was it? England was being ravaged by the plague, London especially was hard hit. When the virus infected the people of Eyam they took steps to self isolate, not allowing anyone into or out of the village for around a year, it devastated the population and there were claims and beliefs they found a cure for it...it's unlikely they did but scientists are looking again to see whether things like self isolation had a positive effect on controlling or eradicating the plague.
If anyone is interested it makes good reading as to how one village coped with the catastrophe and it's helping scientists now work out the efficacy of control and treatment; it's also worth noting the plague virus is still with us, albeit mainly in North Africa.
