Your viruses could reveal your travel history, and much more.


The genomes of two distinct strains of the virus that causes the common lip cold sore, herpes simplex virus type 1, have been identified within an individual person --an achievement that could be useful to forensic scientists for tracing a person's history. The research also opens the door to understanding how a patient's viruses influence the course of disease.

Most people harbor HSV-1, frequently as a strain acquired from their mothers shortly after birth and carried for the rest of their lives. The new discovery was made with the help of a volunteer from the United States. The research revealed that one strain of the HSV-1 virus harbored by this individual is of a European/North American variety and the other is an Asian variety -- likely acquired during the volunteer's military service in the Korean War in the 1950s.

"It's possible that more people have their life history documented at the molecular level in the HSV-1 strains they carry," said Derek Gatherer, a lecturer in the Division of Biomedical and Life Sciences at Lancaster University in the United Kingdom and a member of the research team, which also includes scientists at Georgia State University, the University of Pittsburgh, and Princeton University.
