This sounds like the beginning of a movie. Specifically a “this is how the zombie apocalypse begins” movie.

‘Unbearable’ smelling passenger that caused plane’s emergency landing dies from tissue necrosis

Short from: Russian rock musician went to the Canary Islands for vacation, picked up some sort of “beach infection.” On the flight from the islands to Amsterdam, he began to smell so bad that nearby passengers started to hurl. Crew moved him to the bathroom to try to control the smell; the plane was diverted to Portugal. Stinky guy removed by medical professionals, and later died of the “beach infection.” Unclear how “later” later actually was… hours or days, undefined.

What’s surprising to me isn’t that a guy caught some sort of horrible disease on an island. What surprised me is just how fast it apparently worked; one gets the feeling that when he boarded the flight he might not have smelled so bad, but within a few hours he was so fragrant that his stank was sickening others.

Yikes.
