In late 2015, the World Health Organization released its estimate for the prevalence of the herpes virus. It concluded that approximately 67% of people under 50 were infected with HSV-1, the strain of the virus that causes cold sores on the lips and can also be spread to the genitals. Most carriers of HSV-1 catch the virus from mouth-to-mouth contact early in life. The herpes virus is literally older than humanity itself, and thus far, scientists haven't discovered a cure. However, considering how common it is, the stigma that often accompanies it seems largely unwarranted.
