The disease hepatitis, “hepatitis”, which lately in the media were mentioned, is often underestimated. It is an out-of viruses called acute non-suppurative hepatitis. Originally known 2 species of pathogens, the hepatitis A virus (HAV) and hepatitis B virus (HBV). 2 Virus, which initially could not assign, now called hepatitis C virus (HCV) and hepatitis E virus (HEV). There is probably a lot more of them. On an infection people react differently. First signs of disease occur as to the flu – fatigue, pain and fever. As a result, you can also similar rheumatism symptoms, loss of appetite and jaundice observed. Hepatitis B is well studied molecular biology. If the HB virus in anheftet a liver cell, it reaches through Membranver-MELT into the interior. Immediately, the virus estate with the help of enzymes brought reproduced and the coded instructions executed.

The viruses multiply in the liver cells is very strong in the blood serum of infected patients, the virus concentration at about one billion milligrams per liter rise in the number of virus molecule can amount to over 1000 billion. The propagation speed, and some mechanisms are reminiscent of the HIV virus that cause AIDS. Many patients survive the infection, the liver is working properly again later. About ten percent of the sufferers are the virus but do not let go. Chronic hepatitis can be very fast on the destruction of liver tissue (cirrhosis) and subsequently lead to death. For chronically infected patients can be found viruses in the blood, saliva, in the seminal fluid and in tissues. Pregnant women can the virus before or during birth to their child pass. This infection remind ways to spread AIDS and hepatitis is actually in the same way as HIV transmitted in the past by poorly controlled blood. Under drug addicts the intended non-sterile syringes and other HIV-risk groups are usually a high contaminated with hepatitis viruses. Cirrhosis and liver cancer in these populations clearly widespread.

In 1970, when the world population was about 3.5 billion, because we calculated an accurate assessment 175 million infected people – that is still 5 percent. In China, Southeast Asia, Africa and large parts of some indigenous populations in Greenland was found infection rates of up to twenty percent. As allready told infected have a high risk of developing liver cancer. It is estimated that worldwide annually at least half a million people die from liver cancer, most of them associated with hepatitis.
