I told my relatives to wait. Wait and see what happens to the others first. Confusion and disorientation are side effects of increased immune system activity. Just like how it's harder to function mentally when you have the flu. You get brain fog, and the brain cannot process data. You are physically and mentally exhausted, yet sleep offers no rest. Arthritis patients (an autoimmune disease,) also experience these effects during an arthritis flare up. It becomes unsafe to drive cars, etc.
