Prevalence data from sources such as population surveys can be a useful complement to case based surveillance data for hepatitis C. Case-based surveillance has limitations as most diagnosed cases are chronic in nature and detection of cases depends largely on testing practices. Prevalence data can therefore contribute towards a fuller understanding of the epidemiology of hepatitis C.

This key provides the non-specialist with reference material to help recognise an invasive mosquito species and gives details on the morphology to help with verification.
The seroincidence calculator utilises the combination of serum antibody levels (lgG, lgM, and lgA) at a given point in time to estimate the time since seroconversion, which in turn gives an estimate of annual 'force of infection' in the tested population.
