NOTE :—P. Paralytic N.P. Non-Paralytic.
Much has been made of the possible connection of paralytic
cases with recent inoculation for Diphtheria or Whooping Cough
immunisation and more especially in regard to the combined antigen.
This fact has not been established or confirmed from the cases
in this aroa. Most inoculations for Diphtheria and/or Whooping
Cough immunisations are carried out between the age of 8 months
and 1 year and in the paralytic cases in the ' 1 to 3 yeais ' age group
only one case occurred within two months of immunisation and oven
in this instance the area of paralysis was not in the region of the site
of inoculation.
In the age group ' 5 to 10 years ' one paralytic case occurred in a
child some 4 months after immunisation but here again owing to
the length of time between immunisation and the onset of the
paralysis there was, ostensibly, no connection.
However, in the one paralytic case occurring in the ' under 1
year ' age group there appeared to be a possible connection between
recent inoculation and the area of paralysis and this instance was
reported to the Ministry of Health in accordance with the Chief
Medical Officer's letter of June, 1950.
For further elucidation of the Greenwich epidemic, the following
table has been introduced giving all relevant information in respect
of confirmed cases of Poliomyelitis together with a summary of
possible and apparent relationships.
