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.
Viral hepatitis is a common form of liver disease that affects roughly 1% to 2% of the United States population. It is caused by a diverse group of hepatotropic agents that lead to liver inflammation and cell death. Five hepatitis viruses have been well characterized: hepatitis A (HAV), B (HBV), C (HCV), D (HDV), and E (HEV). HAV, HBV, and HCV are the most frequent causes of viral hepatitis in the United States (Table 1). HDV infection is rare in the United States, except among HBV-infected individuals.
