A total of 9/158 (6%) pediatric patients had fever as the only sign, 6/158 (4%) had gastroenteritis, and 1 (1%) had myelitis and AFP (a 2-year-old girl with no underlying diseases but not fully recovered with quadriplegia and respiratory failure requiring home tracheotomy mechanical ventilation and feeding through gastrostomy). This evidence concerns the gene AFP and myelitis.
