“…28 Interestingly, poor case outcome for EEE was correlated with the length of the prodromal illness phase, with those patients with the shortest prodrome having the worst long-term followup symptoms. This could be because of variation in neuroinvasiveness, fitness, or virulence of different strains of virus, 29 because of host factor variability, 30 or exposure to substances that damage the blood-brain barrier and enhance neuroinvasiveness. 31 In addition to long-term health effects resulting from encephalitis or encephalomyelitis, there are case reports that include sepsis and myocarditis in addition to neurological symptoms.…”
