A mathematical model proves that Bieber fever is one of the catchiest diseases of our time.
Imagine: you’re the parent of an adolescent Justin Bieber fan. At some point, the musical heartthrob has probably struck fear into your heart — the fear that your child is in the clutches of an unhealthy obsession.
What would possess someone to buy up Bieber toys, read Bieber fan fiction, watch Bieber movies, and sleep in Justin Bieber pajamas? The clinical term for this condition is Bieber fever, and according to a Canadian mathematical model, you’re right to be afraid. It’s even more contagious than the measles, one of the fastest-spreading diseases on earth.
