[The incidence of viral hepatitis A in the Hradec Králové Region in the Czech Republic in the last decade].
OBJECTIVE
Viral hepatitis A continues to occur in the Czech Republic due to the high susceptibility of the population and existing opportunities for the transmission of the disease. The aim was to describe and analyse the incidence of viral hepatitis A in the Hradec Králové Region in the Czech Republic in 2005-2014, including the study of two outbreaks that required a different approach of field epidemiologists.


METHODS
In 2015, a retrospective analysis was carried out of the data on the incidence of viral hepatitis A in Hradec Králové Region in 2005-2014. The EPIDAT system where cases of infectious diseases and data from epidemiological investigations are reported was used as a data source for the purposes of the present analysis. In addition, two final reports on epidemic outbreaks of viral hepatitis A from 2014 were assessed.


RESULTS
The incidence of viral hepatitis A at the regional level follows, to a certain extent, the pattern of the incidence of this disease at the national level. The highest number of cases was reported in 2010 due to a country-wide epidemic. The most affected age groups were children, adolescents, and young adults. The incidence of viral hepatitis A in individual years has a significant effect on the emergence of local outbreaks.


CONCLUSIONS
The incidence of viral hepatitis A in the Czech Republic has a fluctuating trend, at both the national and regional levels. The highest incidence of viral hepatitis A was observed in the younger and middle-age categories. The high susceptibility of these population groups suggests the importance of vaccination against viral hepatitis A that confers specific personal protection.Key words: viral hepatitis A - incidence - outbreak - Czech Republic.
