What a horrible disease to suffer from, hopefully this will become a national notifiable disease very soon. I hope the government puts more money into finding a cure for this disease and hopefully a cure is found in the next ten years or so. The pesticide could be in the food chain such as when crops are sprayed or weeds sprayed and then the wind blows the pesticides into fields where livestock earth the grass.
If the victims of this disease live in cities and don’t have contact with pesticides, then that looks like it could be a possibility.
