The World Health Organization (WHO) has recently raised alarms regarding the global prevalence of genital herpes, revealing that over 846 million people aged 15 to 49, more than one in five individuals in this age group worldwide are living with the infection.
This staggering statistic is part of a comprehensive report released by WHO on December 11, 2024, which also estimates that approximately 42 million people acquire a new genital herpes infection annually, equating to about one new case every second.
What is Genital Herpes?
Genital herpes is primarily caused by two types of herpes simplex virus (HSV): HSV-1 and HSV-2. HSV-1 is traditionally linked to oral herpes but can also result in genital infections through oral-genital contact. HSV-2, however, is more commonly associated with genital herpes, transmitted primarily through sexual contact.
The WHO report highlights the recurring and often painful nature of symptomatic genital herpes. While many infections remain asymptomatic, individuals who exhibit symptoms often experience genital sores and blisters, requiring regular medical intervention and impacting daily life.
Genital herpes imposes a massive economic burden, with global costs exceeding $35 billion annually. These expenses include direct healthcare costs, lost productivity, and the social costs associated with stigma and reduced quality of life.
Stigma and Awareness
Dr. Meg Doherty, Director of WHO’s Global HIV, Hepatitis, and Sexually Transmitted Infections Programmes, emphasized that managing herpes could also indirectly reduce HIV transmission. The overlapping transmission pathways between the two infections make addressing herpes a critical public health strategy.
Despite its prevalence, Dr. Sami Gottlieb, a WHO Medical Officer, noted that stigma surrounding genital herpes often inhibits open discussions and proactive prevention measures. “Breaking this silence through awareness campaigns is crucial to improving the lives of millions globally,” Gottlieb stated.
While condoms significantly reduce the risk of transmission, they are not entirely foolproof. To minimize spread, individuals with active outbreaks are advised to abstain from sexual activity. Furthermore, antiviral medications, such as acyclovir and valacyclovir, are effective in reducing outbreak frequency and severity but do not cure the infection.
The WHO report advocates for comprehensive HIV testing for individuals with genital herpes symptoms, alongside the potential use of pre-exposure prophylaxis (PrEP) to prevent HIV transmission.
Global Prevalence and Statistics
The sheer scale of genital herpes infections highlights its global reach:
- 3.8 billion people under 50 are infected with HSV-1 globally.
- 520 million people aged 15–49 are affected by HSV-2.
- More than 205 million people experience symptomatic episodes annually.
Women are disproportionately affected due to biological factors, with higher transmission rates observed from male partners.
