England's genital herpes cases are climbing despite an overall decline in sexually transmitted infections, marking a concerning reversal in public health progress.

The uptick defies the downward trend across most STIs, which dropped significantly in 2023 following pandemic-related testing disruptions. Health authorities attribute the herpes surge to delayed diagnoses and potential behavioral shifts in how young people approach sexual health screening.

Genital herpes, caused by the herpes simplex virus (HSV), ranks among England's most prevalent STIs. The virus remains dormant in nerve tissue after initial infection, meaning transmission can occur without visible symptoms. This asymptomatic shedding complicates prevention and contributes to underdiagnosis.

Young people face the highest infection rates across all STI categories. Testing delays during COVID-19 lockdowns left backlogs that extended well into recovery phases, allowing undetected cases to spread. As sexual activity normalized post-pandemic, transmission increased among populations with lower testing rates.

Public health officials stress the necessity of routine STI screening, particularly for sexually active individuals under 25. The UK's sexual health services recommend annual testing for young people with multiple partners or those in new relationships.

Genital herpes carries long-term health implications beyond initial infection. Recurrent outbreaks cause pain and discomfort, while infected individuals face stigma surrounding disclosure. Pregnant women with active herpes require antiviral treatment and potential cesarean delivery to prevent neonatal transmission, which risks serious neurological complications.

The rise highlights gaps in sexual health awareness and access to screening. Many infected people remain unaware of their status, perpetuating silent transmission chains. Public campaigns must target young adults with messaging about testing importance and symptom recognition.

Authorities now push expanded screening capacity and improved access to sexual health clinics. Addressing the herpes surge requires combining prevention education with normalized testing culture among younger populations.
