This is some of the reasons I get prepared. I make my own colloidal silver and have food grade H2O2 also have the Dr Bob Beck machine for electrifying the blood. Most all these virus have a life cycle and than die away on there own.
We live in a 'global village' nowadays. It could happen.... And all too easily.
I remember when England held the rugby World Cup some years back. People came from all over the world - and brought their viruses with them.
The same when the EU expanded to include Eastern Europeans and many of them came here looking for work and opportunity.
If it spreads to Nigeria and Gambia we would be in trouble. Then because of the number of travellers, business and holiday, it could break out and go global.
But lets hope not ...
