Early throat recovery suggests possible transmission risk; leaves open precise contagious period and infection control needs.
Virus was recovered from 4 of 7 throat swabs and from 3 of 9 throat washings of poliomyelitis patients collected during the first 3 days after onset of symptoms. In another series of 16 throat washings collected from 3 to 13 days after onset, virus was isolated from 2 patients 11 days after onset of disease.
