Theoretically, true, but practically speaking, there are few death certificates filled out "unknown" as a cause of death. Certainly not a million out of 2.4 million deaths a year to match the 2 million unexplained deaths since 2008 mentioned in the article.

Except this news story is about some "unexplained lung disease". With all the attention focused on H1N1 and every cough and sneeze lately, could we really have missed this many people dying from some lung disease? Well, maybe if they were all driving a certain Japanese brand of car when they crashed driving themselves to the hospital...ooooooh, that's a juicy new conspiracy theory!
