My 19 year old son was recently on a training mission for the national guard at camp ripley minnesota. During his time there they were battling with ticks, mosquitoes, and spiders, among other insects. My son was assigned to bed rest while there due to a bug bite of some sort causing an intestinal infection. They were informed after returning that some of the soldiers were being diagnosed as having encephalitis and if any of them experienced symptoms they should be tested. So after being home 2 weeks my son is involved in a serious car accident and after 2 days of fighting passed away. The day after his death I am informed by the passenger with him that before the accident happened and the cause of the accident is because my son was having a seizure of some sort. He has never experienced a seizure before. My son just passed away yesterday but had been given blood due to his injuries. Blood was drawn before he was given blood however. Is it too late or can anything be done to find out if this was the cause of the seizure?
