European Center for Disease Control present this new
technology during the World Health Day in which the year’s theme was food
safety.
On this occasion, ECDC launches the sero-incidence
calculator tool for human Salmonella and
Campylobacter infections and
publishes the ‘Surveillance report on the seven priority food- and waterborne
diseases in the EU/EEA, 2010-2012’.
Campylobacteriosis and salmonellosis are the two
leading gastrointestinal diseases reported in the European Union. However, the
reported number of cases represents only a small fraction of all infections
that actually occur.
As a consequence, an ECDC funded project has developed a
tool which provides additional information. The tool utilizes the measured
combination of serum antibody levels (IgG, IgM, and IgA) at a given point in
time and estimates the time since sero-conversion. This in turn gives an
estimate on the frequency of exposure to Salmonella and Campylobacter in the
tested population.
This tool builds upon an EU-wide study [1] on sero-incidence
of salmonellosis which produced estimates showing tenfold differences by
country in the frequency of exposure to Salmonella.
The sero-incidence tool
enables the calculation of estimates for monitoring the effects of control programs
as they provide more accurate information on the pressure of infection to
humans in EU/EEA countries. Despite the decrease in the number of reported
salmonellosis cases, this tenfold difference shows that continued surveillance
and vigilance remains of utmost importance.
The
‘Surveillance report on the seven priority food- and waterborne diseases in the
EU/EEA 2010-2012’ is the second dedicated epidemiological report for
non-typhoidal salmonellosis, typhoid and paratyphoid fever, campylobacteriosis,
Shiga toxin/vero-cytotoxin-producing
Escherichia coli (STEC/VTEC) infections, listeriosis, shigellosis and
yersiniosis.
For most of the gastrointestinal diseases, the
case-fatality rate was below 1%, except for listeriosis, for which the average
case-fatality rate was 16% between 2010 and 2012. Of special concern are Listeria infections among the elderly,
where case numbers have increased sharply, particularly in men over 65 years of
age.
