A survey of hepatitis B and C prevalence amongst the homeless community of Prague.
BACKGROUND
Viral hepatitis B (VHB) and C (VHC) are a major health concern worldwide, with 170 million people chronically infected and at risk of liver cancer, cirrhosis or liver failure. Since no vaccination is available against VHC it is important to understand how to prevent future infection. The modes of transmission include intravenous drug use (IDU), blood products, tattooing and, to a lesser extent, sexual intercourse. Homelessness is a risk factor of VHB and VHC because of the environments and behaviours associated with homeless communities such as poor hygiene, nutrition and high levels of IDU. The aim of this project was to determine the prevalence of VHB and VHC and its risk factors amongst homeless community of Prague, Czech Republic.


METHODS
Ninety-eight individuals of the Prague homeless community were interviewed and tested for VHB and VHC infection markers.


RESULTS
The prevalence of both VHB and VHC was 26.5%. The major risk factors in this population were past and present IDU, young age and sharing the paraphernalia used by intravenous drug users (e.g. spoons, foils and filters).


CONCLUSIONS
With the exception of age, all these risk factors could all be targeted in order to combat the major public health concern that VHB and VHC poses to the homeless community of Prague.
