Around two-thirds of humans, according to Smithsonian Magazine, are infected with at least one of the two types of herpes, HSV-1 and HSV-2. It's estimated that 87% of people with the latter are without clinical diagnosis. The notoriously tenacious herpes virus hides deep in the human body's central nervous system, but "molecular scissors" might be the way to splice it out. This would occur by introducing a human-made enzyme to "snip" genes at crucial points, removing the virus where it's embedded. This direct path is still being researched, however, but to learn more about what could be, head over to Smithsonian.
