[Futurama] How did Fry go 11 years in the future without catching a cold

Bonus Question: Why aren't people whom arrive from the 2000s quarantined after being unfrozen so they don't spread the cold?

By the year 3000, a lot of diseases and viruses have likely been eradicated... Especially with the couple of "refreshes" we've seen the Earth go through in the time lapse during Fry's slumber.

Fry comes from the 20th Century... An era rampant with viruses, bugs, diseases, etc.  

Fry's immune system is better equipped at fighting multiple viruses at once, but when there's fewer viruses to fight off it's even BETTER at handling them than before.
