An epidemiological study about viral hepatitis
Viral hepatitis remains a public health threat in Hong Kong. The major interest of this epidemiological study would be the distribution and determinants of viral hepatitis in Hong Kong population. This study is expected to provide updated information for public health policy formulation by identifying risk factors and targets for disease control and prevention.
As most people with hepatitis are unaware of their infection status, testing for viral hepatitis is the gateway for access to appropriate prevention and treatment services. Getting tested for prompt disease management could not only maintain the health of an individual, but also reduce its public health burden by minimizing the transmission potential in the community.
This is a territory-wide cross-sectional household survey on two types of vaccine-preventable viral hepatitis, namely hepatitis A and hepatitis B.
All members in selected households are invited to complete a questionnaire and submit blood samples to the Research Team for serology testing. Blood samples could be taken in person at the research centre or by submitting self-collected dried blood spot testing kits.
Aim and objectives
This study aims to enhance the capability of public health authorities by assessing the susceptibility and transmission potential of hepatitis A and B in the general population in Hong Kong.
The objectives are to:
- determine the population-level seroprevalence of hepatitis A and B in Hong Kong,
- examine the risk factors, vaccination history and intention to get vaccinated against viral hepatitis, and
- assess the transmission potential of hepatitis A and B in the general population by mathematical modelling.
