Two contacts of patients with poliomyelitis were shown to have viremia. In both instances type 1 virus was found in the stool and in the blood. Neither of these contacts showed detectable neutralizing antibodies to the virus at the time the serum specimens were collected. It was because they were excreting virus and were without detectable antibodies that they (as well as six other similar persons) were studied for the possible presence of viremia.
