this is all the business of big pharma companies and some countries. First they produce viruses/diseases then medicines to cure them, then medicine to cure side-effect of medicines. for example cure for swine-flu was produced before 2-3 years from virus. So to sell the medicine the virus was produced and was spread in country whose economy was the raising. The country was targeted, & then they have to purchase medicine from this BIG country. And loose there economy. We can also see example of Brazil how one neighbouring country gave them obesity through food. GMO
