Key result
Poliomyelitis virus appears in ~80% of intestinal discharges among affected household members.
The study demonstrates widespread distribution of poliomyelitis virus among members of affected households.
Highlights potential household transmission via asymptomatic shedding; leaves open modern surveillance and contact-tracing implications.
A study of 4 households attacked by poliomyelitis provided evidence of widespread distribution of virus in the members of these units. There were 20 members in these households; 16 had poliomyelitis virus in their intestinal discharges; 7 had virus in the oropharynx.
