Meta-analysis confirms Zika link to Guillain-Barre Syndrome

According to a recently released study, sufficient evidence now exists to conclude that the mosquito-borne Zika virus triggers Guillain-Barre Syndrome (GBS). The study, published in the journal PLOS Medicine, reviewed all Zika literature published on or before May 30, 2016. In total, a panel of experts assessed evidence of causality in 36 studies that looked at Zika and GBS.

As a reminder, Guillain-Barré syndrome (GBS) is a disorder in which the body's immune system attacks part of the peripheral nervous system. Weakness and tingling sensations in the legs and arms are usually the first symptoms GBS. These symptoms can last a few weeks or several months. Most people fully recover from GBS, though some people have permanent damage.  Death from GBS is very rare.
