One new case of acute hepatitis B and two chronic versions of the same disease. This number is reported by recent data from the State Institute of Public Health (SZÚ) in Prague in August. There are dozens of cases in the Czech Republic. However, the virus not only in the Prague Basin has not been new since prehistoric times, according to the mentioned research.
In prehistoric times, however, any treatment of a sick member of the tribe would fall on the shaman in the cave, not on the surgery. The occurrence of the virus is confirmed by expertise of skeletal remains from prehistoric burial grounds. Experts studied dozens of samples of prehistoric inhabitants of Europe, Asia and America, who lived ten and a half thousand to 400 years ago.
“As part of the research, we worked with twelve samples from five localities in Prague, Central Bohemia and Pardubice,” Michal Ernée, an archaeologist from ARUP, introduced the domestic part of the research. The researchers subjected two samples from Ďáblice, dating from the Early Bronze Age, to demanding expertise.
In the summer, scientists will open historical sites and present a Hussite seat in Prague
From the vicinity of the capital, researchers studied fragments from Brandýs nad Labem, Hostivice and Vliněvsi in the Mělník region. These were people living in Eneolithic cultures of bell-shaped cups and string pottery. In Brandýs, similarly to Ďáblice, these were fractions, the origin is dated to the Early Bronze Age.
Prehistoric connection with HIV
However, researchers from ARUP point out that this is not the only place where our ancient predecessor suffered from hepatitis B at dawn.
“From the territory of Bohemia, we have documented the occurrence of hepatitis B on several other skeletons, the oldest of which belongs to the Eneolithic culture of the Rivnice region and is dated to around 3,000 BC,” explained Michal Ernée.
The hepatitis B virus is highly resistant, surviving in a drop of dried blood for several weeks.
The results of the study mapped the way in which the virus spread in prehistoric times and its changes. “At the same time, however, they revealed unexpected patterns and overlaps to this day,” pointed out Eliška Zvolánková, a spokeswoman for the Academy of Sciences of the Czech Republic. The findings of the research show that the virus was present in Europe 10,000 years ago. That is, even before agriculture began to spread here. The scientist was surprised.
“We think of many human pathogens that they appeared after the agricultural way of life was used and spread. However, hepatitis B apparently affected the prehistoric populations of hunter-gatherers, “said Johannes Krause, director of the Department of Archaeogenetics at the German Planck Institute, which is at risk of research.

Even the virus has undergone changes in ancient history. “In the second half of the 2nd millennium BC, a sudden decline in the diversity of hepatitis B variants,” the research concludes. All prehistoric variants, which then appeared in our latitudes, belong to the new lines. And they still prevail today.
It doesn’t have to be absolutely true. “But one of the original prehistoric variants seems to have survived – it has evolved into a rare genotype that has been ‘reborn’, apparently during the spread of HIV,” the study said. Whether this is really the case, I have to confirm further research.
Hundreds of sunken objects were discovered by archaeological research a few years ago in Ďáblice. The oldest of this localities appears to be a funeral district from the turn of the Stone and Bronze Ages, ie the period before 2,000 BC , ”The archaeologists report.
During the research of one of the localities in Hostivice, the researchers found 455 objects and 1,630 stake pits. In addition to storage pits and production facilities, they discovered a grave with the remains of an adult.
They found another grave in a common residential pit. For the most interesting discovery from Brandýs, experts are looking for a storage pit with the broken skeletons of two people. The site in Vlinevs is one of the most interesting of its kind, studied by archeology from the ARUP. They documented 304 graves and 57 housing estates containing human remains.
