How increased pertussis vaccination coverage is changing the epidemiology of pertussis in Italy.
2005
Abstract The epidemiology of pertussis in Italy is described by using data from the statutory notification system and from seroepidemiology studies. Starting from the 1990s, the incidence of pertussis in Italy has shown a sharp decline and is now at the lowest level ever reached. During this time period vaccination coverage has increased from 88% in 1998 to 95% in 2003. In 1996–97, the prevalence of subjects with levels of IgG antibodies against PT greater than 2 EU/ml was 77.6%. The increase in vaccination coverage will probably change the pattern of disease transmission and increase the number of susceptible adults, unless administration of booster doses to adolescents and adults is consi…
European Sero-Epidemiology Network: standardisation of the assay results for pertussis
2003
A standardisation process was developed in order to compare and harmonize serological results of pertussis toxin (PT) antibody measurements performed by laboratories using different technical procedures for detection. This involved the development of a common panel, of sera by a designed reference centre, the distribution of the panel to each participating laboratory for testing with their routine methods, the comparison of the obtained results to those of the reference centre, and the calculation of standardisation equations by regressing the quantitative results against those of the reference centre. As a cut-off indicative of protection against pertussis has not yet been defined, a parti…

El Gran Catharro de 1580 ¿gripe o pertussis?
2005
The gran Catharro (1580) is considered the first influenza epidemic. The analysis of various testimonies of the time may offer some doubts about whether or not it was so; and data strongly support that it was a pertussis epidemic.
