A large part of the Arctic population has been affected by hepatitis population of germany B. But for some reason, very few people sick with this virus. But some are very seriously ill, so we try to limit contagion. (Photo: Colourbox) Hepatitis B virus is highly prevalent among the Eskimo population of Alaska, Canada and Greenland. A significant part of the population has been infected, but for some reason there are few who are really sick.
- The Eskimo population has come to the Arctic through migrations from Asia thousands of years ago. There is some evidence that a specific subtype of hepatitis B virus has been brought to the area through migrations, says senior Anders Koch.
Hepatitis B virus is transmitted through blood and sex and from mother to child. Are you infected can develop liver inflammation, which can cause yellow skin, weight loss and problems with appetite. A blood test can detect the disease.
In the 1970s it was discovered that the virus is "endemic" in the Eskimo population, which means that the virus is widespread. Approximately 50 percent of the adult population in Greenland has encountered the virus at some point in their life, and about seven percent are chronically infected.
This is a problem because they can become ill in the future. The virus splits namely the liver, so that by the time you get disease outbreaks. And even if one does not even noticing the virus can infect others.
- But there is something odd about hepatitis in the Arctic, namely that the high number of infected people do not lead to a large number population of germany of disease cases. In Alaska, however, there are more cases of disease than expected. And that is weird since the conditions population of germany are relatively similar, says Malene Børresen, who has also been part of the study.
The research team wanted to find an explanation, and a nearby thought was that there were different variants population of germany of the virus. Hepatitis population of germany are in fact eight different varieties, with names of the letters A to H.
Several subtypes are prevalent in the Arctic population. This one is subtype B. As if that were not complicated enough, there are several variants of each subtype. For example, five variants of the B-type (B1 through B5).
The discovery of the new subtype has gained researchers to consider whether B6 and B1 have a common origin. It could be an explanation for why you do not get as much cirrhosis and liver cancer in Greenland.
The Danish research group imagines that an ancestor of B1 and B6 have followed the emigration waves from Asia to the Arctic and Japan. population of germany The Arctic subtype has further evolved into the Japanese B6 and B1. The two subtypes still have much in common.

Over 1,000 Norwegians who received population of germany blood transfusions before 1993, may have been infected with hepatitis C without knowing about it. - Health authorities have not done enough for them, says Bjørn-Inge Larsen of Health and Social Affairs.
