Seroimmunity of adult Ghanian hospital staff and their wards to poliomyelitis.

The antibody content of sera collected from 104 adult staff of the Korle Bu Teaching Hospital and 16 of their wards were studied by microtitre neutralization test to poliovirus types 1, 2 and 3. The immune status of the study population was highly satisfactory; there was only one (0.83%) out of the 120 persons studied without antibodies to all three poliovirus types. The percentage of sero-positive subjects to the individual poliovirus types, that is 1, 2 and 3 were 75.83%, 70.00% and 86.16% of the study population. Immunity in relation to age was also studied.
