Hepatitis

Six different viruses are now known to cause hepatitis—hepatitis A, B, C, D, E and G. Hepatitis A, B and C account for almost 95% of all cases of viral hepatitis. The other strains are uncommon.

Hepatitis E virus capsid, molecular model. This virus causes the disease hepatitis E in humans. Transmitted by faecal-oral contact, this virus causes low-level liver inflammation that can become more severe. In viruses, the capsid is the protein shell that encloses the genetic material. A capsid consists of subunits called capsomeres that self-assemble to form the shell seen here. Here, this shell, approximately spherical in shape, has icosahedral symmetry. One of the functions of the capsid is to aid the transmission of the viral genetic material into host cells. The cell mechanisms are then used to produce new virus particles.
