Case Report: We describe a 69 year-old female who became ill with poli
o after having changed the nappies of her grandchild who, six weeks ea
rlier, had been vaccinated with oral live-vaccine against polio. Anamn
esis and neurological status with limp paralysis in both legs oblige,
with their implications, that the patient be isolated initially. Proof
of poliomyelitis was to be found, in addition to typical medical find
ings, in the virus analysis in the stool, determined by polymerase cha
in reaction and in the discovery of antibodies from the serum by means
of a neutralisation test. The neurological disorder could not be trea
ted medically. The main priority was intensive physiotherapy. With wal
king aids the patient had only limited walking ability three months la
ter. Conclusion: Discussed are: the meaning of anamnesis and specific
diagnosis of illness and immune deficiency, the morbidity and necessit
y for certain protection against children recently vaccinated with liv
e-vaccine, also the provision for an individually structured plan for
vaccination after satisfactory information.
