Our paper on the second plague pandemic is now finally published:
www.pnas.org/doi/10.1073/...
We present 11 new Y. pestis genomes from around Europe and introduce a new approach to refine the dating of ancient genomes that helped us to contextualize 75 plague genomes of the Second Pandemic.

I hope that other researchers will now go back through their ancient genomes and find more carriers of integrated HHV6 viruses, as this is the first peek at an exciting global story.

It's tough to do molecular clock estimates on how fast these viruses mutate, because they can switch back and forth between evolving at the human mutation rate (relatively slow) and their own viral mutation rate (faster). Ancient DNA can currently only give us minimum ages for these viruses.

These viruses infect ~70% of adults, but between 0.5-3.5% of people worldwide actually have a 6A or B virus *in their genome*, hiding in a telomere, inherited from an ancient ancestor. We can see these ancient integration events were already present in Europe hundreds of years ago - minimum.

This work is likely just the start of better understanding the deep history and spatio-temporal dynamics of these importance viruses.

There are likely many more HHV-6A/HHV-6B to be found in ancient human genomes to further support direct calibration of the age of integrated viral clades and acquired HHV infections.

Ancient genomes show that these viruses have been co-evolving with human populations across Europe, dating from early Italy to medieval England, Belgium, and Russia; underscoring a deep, ongoing host-virus history.

Through screening of ~4,000 archaeological human samples, this work reconstructed 11 ancient genomes of HHV-6A and HHV-6B. These viruses still infect many of us today.
