Doctors Suspect Zika in Paralysis Spike


An affliction that causes paralysis and even death is on the rise in South America. Doctors believe it could be linked to the Zika virus.

Guillain-Barre is an autoimmune disorder that strikes after an infection, such as the flu.

Patients become extremely weak and sometimes lose the ability to move. About one-fifth of them die.

The World Health Organization says cases are on the rise in Brazil, Colombia, El Salvador and Venezuela -- countries that have been hit hard by the mosquito-born Zika virus.

So far, no link has been established, but doctors believe hundreds of cases of Guillian-Barre are associated with Zika.
