This table shows direct medical cost results for specific attack rates across by various at risk groups for all states combined. The costs are in millions of 2016 United States dollars [estimate (range: more conservative-less conservative)]; US = ultrasound. CNS = central nervous system disorders. GBS = Guillain-Barré Syndrome.
