More than 3.7 billion people under the age of 50 are infected with herpes simplex virus type 1, which in most cases causes “cold sores” around the mouth, according to the first global estimates of the infection by the World Health Organization (WHO).

The new estimates published today in the journal PLOS ONE also note that the herpes simplex virus type 1 is an important cause of genital herpes.

Herpes simplex virus is categorized into two types: herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2).

Both are “highly infectious and incurable, “ and while HSV-1 is primarily transmitted by oral-oral contact and in most cases causes orolabial herpes or “cold sores” around the mouth, HSV-2 is almost entirely sexually transmitted through skin-to-skin contact, causing genital herpes.

“Access to education and information on both types of herpes and sexually transmitted infections is critical to protect young people’s health before they become sexually active,” according to Dr. Marleen Temmerman, Director of WHO’s Department of Reproductive Health and Research.

“The new estimates highlight the crucial need for countries to improve data collection for both HSV types and sexually transmitted infections in general,” Dr. Temmer-man said.
