Reply To: 2 cases in my wifes family & relative in past 12 months

GBS is not inherited, it is acquired, although there may be a genetic predispisition to it. The incidence in North America is about 1.5 to 2.0 per 100,000 annually, according to Parry and Steinberg. It is believed to be triggered by an infection and there may be many different infective agents. Often, the cause is ideopathic, because the infection need not have clinical symptoms to lead to GBS.
