Casey's insights aim to inform readers about the potential consequences of these changes and the importance of understanding the broader implications for our planet.

Hepatitis delta virus which causes severe acute and chronic liver disease was discovered following the detection of a novel antigen-antibody system in hepatitis B virus carriers. Currently, HDV is classified as a subviral satellite of hepatitis B virus. However, unlike other satellite viruses, the dependence of HDV on HBV is limited solely to the provision of an envelope of hepatitis B surface antigen for virus assembly. Research into the molecular virology of the HDV life cycle has revealed a fascinating collection of biology. These insights are now beginning to be translated into new potential treatment strategies. There are currently still an estimated 15 million HDV carriers worldwide.
