A comet is made up of material that gets evaporated easily by the Sun, so comets lose mass with each passage around the Sun. As much as one percent of their masses can be blown away. Comets may start out very icy, but this is not how they'll look for long, since the ice is the first thing to go.
Classified as toxic or drug-induced (idiosyncratic) hepatitis, non viral hepatitis is an inflammation of the liver. Most patients recover from this illness, although a few develop fulminating hepatitis or cirrhosis.
The name of each type of viral hepatitis condition corresponds to the virus that causes it. For example, hepatitis A is caused by hepatitis A virus (HAV), hepatitis B is caused by hepatitis B virus (HBV), and hepatitis C is caused by hepatitis C virus (HCV). Scientists do not know exactly how these viruses actually cause hepatitis.
