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.
Several different viruses, named the hepatitis A, B, C, D, and E viruses, cause viral hepatitis. All of these viruses cause acute, or short-term, viral hepatitis. The hepatitis B, C, and D viruses can also cause chronic hepatitis, in which the infection is prolonged, sometimes lifelong. Chronic hepatitis can lead to cirrhosis, liver failure, and liver cancer.
