when he returned home doctors found out he had worms

it is a often lethal screw worm which is not supposed to infect humans

it is lethal in 33% of cases (for humans, not for livestock)

but infections are very rare

the worm lives mostly in south america only, and not in the southernmost parts, it is accustomed to warmth

this is a pig/cow/dog parasite and unfit for humans, the worm cannot even reproduce inside a human body but it can still wreak havoc

Nixon said the risk for public health is minimal as it is very unlikely the man spreas worms further

it could become a problem if he infects a dog or a pig or something with his worm but its very unlikely occurence
