HC Deb 18 April 1956 vol 551 c89W
Mr. Peter Freeman

asked the Minister of Health whether he will give a list of host factors which he is advised may predispose to poliomyelitis.

Mr. Turton

I am advised that there is little by way of direct evidence as to the host-factors predisposing to poliomyelitis but that, if infection with poliomyelitis exists or shortly follows, excessive muscular exertion or such local injury as tonsillectomy or certain injections may slightly increase the risk of paralysis.
