To sound out prevalent opinions among health authorities in Europe con
cerning the control and prevention of congenital toxoplasmosis (CT), a
questionnaire was sent to the 28 WHO member countries in Europe. The
questionnaire was returned by 23 countries. Only 7 countries recommend
systematic screening of pregnant women. The reasons given by the 14 c
ountries which do not recommend systematic screening are diverse: reco
mmendations are in preparation, unfavourable cost-benefit return, abse
nce of satisfactory treatment, programme not possible, incidence level
too low, etc. 11 countries have a surveillance system for CT, of whic
h only 3 are among the countries which recommend systematic screening.
However, the absence of a multidisciplinary approach does not permit
proper surveillance of cases. It appears from this survey that control
of CT is undertaken in a very heterogeneous manner in Europe and no c
ountry has a programme whose impact on CT can be measured. So far, the
European experience does not permit conclusions either in favour of o
r against a programme for the systematic screening of CT. However, cos
t-benefit analysis plays a very important role in determining whether
such a programme should be implemented. Parameters such as the securit
y of diagnosis (standardization of methods, quality and experience of
the laboratories) and the monitoring of cases (definition, multidiscip
linary approach to the surveillance and long-term treatment of patient
s, national collection of case reports, evaluation of the programme) a
re indispensable for the implementation of an effective surveillance s
ystem.
