Basically it is the first major flu strand that could become a pandemic, since about 40 years(Hong Kong flu of 1968). The most deadly flu pandemic, was the Spanish flu of 1918. It affected about 20% of the world's population at the time, and killed anywhere from 20-100million people. With the medication of today, it shouldn't be a problem though.
