Brazil, Colombia, El Salvador, and several other countries have detected more GBS cases than usual, just as French Polynesia saw a surge of GBS cases during a Zika outbreak there in 2013 and 2014, according to the World Health Organization.
In Colombia, three people with Zika-associated GBS have died, and health officials are investigating six other deaths. The country typically reports 240 or so cases of GBS each year, but had 86 in just five weeks in December and January, a few months after Zika was identified in Colombia, according to the WHO.
