Both patients developed flexic type of pure motor weakness in all four limbs without bladder bowel involvement, following 2 to 3 days of fever and malaise. Higher mental functions were normal. Serum potassium level was very low; 2-2.5 m mol/l. Non-structural protein (NS(1))-antigen and immunoglobulin M-antibody for dengue were positive in both patients.
