![]() The potential for non-sexual HPV infection HPV can remain infectious in a typical room environment for days further increases the possibility for non-sexual transmission. A couple of studies detected abundant HPV DNA on the fingertips of individuals with anogenital infections, providing a potentially important vehicle for self-inoculation and inoculation of partners. Several studies have provided evidence for a route of vertical transmission HPV from mother or child. While the actual number of non-sexual transmission of HPV is unknown, and will be difficult to determine, there is a risk for non-sexual transmission. Often the potential for non-sexual infection by HPV is ignored or dismissed by healthcare professionals. While HPV is commonly known to be transmitted by sexual contact, the public is unaware of the risk of HPV infection through non-sexual transmission. Nearly all cases of cervical cancer are the result of HPV infection, as well as a significant number of anogenital and oropharyngeal cancers. Human papillomaviruses (HPV) are responsible for over 5% of human cancers worldwide. Our results suggest that healthcare facilities using endocavitary ultrasound probes need to strongly consider disinfection methods that are effective against HPV. While HPV is highly resistant to OPA, high-level UVC radiation offers an effective disinfection practice for ultrasound probes. ![]() The automated Antigermix S1 device showed excellent efficacy against HPV16 and HPV18 whereas OPA showed minimal efficacy. Infectivity was determined by the abundance (qRT-PCR) of the spliced E1^E4 transcript in infected recipient cells. Hypochlorite was included as a positive control for viral deactivation. Efficacy testing were performed with the automated device, Antigermix S1 device (UVC radiation at 253.7nm) and 0.55% OPA in quadruplicate with matched input, neutralization, and cytotoxicity controls. Stocks of infectious authentic HPV16 and HPV18 virions were dried onto carriers with a 5% (v/v) protein soil or 4ppm hard water. In our present study we analyzed efficacy of using high-level ultra-violet C (UVC) radiation against HPV16 and HPV18 using a hard-surface carrier test. ![]() we have previously shown that HPV is resistant to some high-level disinfectant (HLD). It has been demonstrated that these probes can remain contaminated with high-risk HPV even when approved disinfection protocols have been performed. The cavities examined, vaginal canal and cervix, anal canal, and oral cavity are all areas commonly infected with the human papillomavirus (HPV), thus making them susceptible to contamination by HPV. Endocavitary ultrasound probes are part of a commonly used procedure in the clinical arena.
