Determine the term Poliomyelitis - Brian diseases
Poliomyelitis is an acute infectious disease caused by a virus that has a special affinity for the motor neurons of the spinal cord and sometimes for the motor neurons of the cranial nerves. The loss of these motor neurons causes paralysis and wasting of the muscles. If the motor neurons of the respiratory centers are attacked, death can result from asphyxia. The occurrence of the disease was sporadic and sometimes epidemic until the Salk and Sabin vaccines were developed in the 1950s and 1960s. Since then, poliomyelitis has been well controlled.
