Epidemiological
surveillance
Epidemiological surveillance is effective in controlling
epidemic diseases. Quality basic data and its application in
quick and appropriate decisions are key elements of any
healthcare system. The role of epidemiological surveillance
is essential in planning, managing, allocating and
mobilizing resources, in early detection and reaction to
epidemics, as well as in the assessment of prevention
programs and their impact.
Most countries are in the process of decentralizing
healthcare, which implies that local decision-makers have
functional knowledge of health data. The CCISD has created
epidemiological surveillance centers, both at the regional
and national level, in six West African countries (Burkina
Faso, Benin, Côte d’Ivoire, Guinea, Mali and Niger), has
trained the agents and supplied computer equipment. The
agents have become more and more apt at collecting,
analyzing and presenting the data, as well as providing fast
and concrete feedback. Due to the success of this project,
more than 100 epidemiological surveillance centers have
adopted this type of intervention.
To extend epidemiological coverage in these countries,
additional centers are being planned for the second phase of
the Project.
The CCISD is attempting to progressively introduce the
peripheral data/analysis process in the NHISs. Known as
“integration”, this process also includes networking,
Internet data and experience sharing, as well as
distribution of training and information material. The
integration process pertains to diseases which are at the
height of healthcare concerns. Integrated disease
surveillance is a newly adopted strategy of member countries
of the WHO.
