The correct answer is - 6%
AIDS is a disease that is very devastating, especially because there hasn't been found a cure for it so far. The disease is not equally distributed throughout the world, but it is mostly represented in the so called ''third world countries'' in Africa, while the number/percentage in the highly developed countries is relatively low.
It is estimated that around 6% of the people with AIDS are living in Western and Central Europe, and North America, which accounts for approximately 2,2 million people.
It is not 100% sure how big the number is actually because lot of people don't know that have it, some because they don't suspect it, some because they do not have the conditions in order to be examined.
