Recent studies show that the strain of the VNG-1 virus, which causes herpes on the face, emerged some 5,000 years ago in the bronze age, when large-scale migrations to Europe took place.

Herpes has been history for millions of years, and many species, ranging from bats to corals, are affected by various forms of the virus, but despite its prevalence, it is difficult to find examples of ancient infections.

A study published in Science Advances says that the spread of facial herpes coincided with the emergence of new cultural practices — kissing as manifestations of their feelings.

The facial herpes virus can hide in its master for the rest of its life and be transmitted in oral contact, so mutations have been slow for centuries and millennia.

Each type of primate has a form of herpes, so the authors assume that the virus has accompanied the human race since it left Africa.

But about 5,000 years ago, there was an event that caused one strain of herpes to spread more than the others, and perhaps the number of infections increased because of the kisses, the authors concluded.
