The commercial unavailability of a vaccine against HSV is hampering the global herpes simplex virus treatment market. There is no approved treatment for HSV infection, but some antiviral agents are used in symptomatic disease treatment to avoid further complications. Despite being one of the leading infectious disease, there is no approved vaccine for HSV because the herpes virus is more evasive and complicated than other such infections. So, developing a vaccine for this condition has is still a challenge.

Type Insights

The Herpes Simplex Virus-1 (HSV-1) segment accounted for the largest market revenue share of 83.73% in 2023 and is estimated to be the fastest-growing segment over the forecast period. The segment dominance is attributed to the increasing prevalence of HSV-1 infection among population. According to the WHO 2022 report, nearly 3.7 billion individuals worldwide under 50 years (67%) have HSV-1 infection. Most HSV-1 infections are acquired during childhood. Moreover, the market is driven by the increasing risk associated with the transmission of HSV-1. The infection may transmit via contact with virus through saliva, sores, or even through genital area through oral-genital contact.

Famciclovir and valacyclovir have higher prescription rates than acyclovir due to their greater oral bioavailability and lower dose frequency.
