Transmission HPV is most commonly transmitted through penetrative sex. While HPV can also be transmitted via non-penetrative sexual activity, it is less transmissible than via penetrative sex. There is conflicting evidence about the effect of condoms on transmission of low-risk HPV. Some studies have suggested that they are effective at reducing transmission. Other studies suggest that condoms are not effective at preventing transmission of the low-risk HPV variants that cause<unk> s. The effect of condoms on HPV transmission may also be sex-dependent; there is some evidence that condoms are more effective at preventing infection of males than of females. The types of HPV that cause<unk> s are highly transmissible. Roughly three out of four unaffected partners of patients with<unk> s develop them within eight months. Other studies of partner concordance suggest that the presence of visible<unk> s may be an indicator of increased infectivity; HPV concordance rates are higher in couples where one partner has visible<unk> s. Latency and recurrence Although 90% of HPV infections are cleared by the body within two years of infection, it is possible for infected cells to undergo a latency (quiet) period, with the first occurrence or a recurrence of symptoms happening months or years later. Latent HPV, even with no outward symptoms, is still transmissible to a sexual partner. If an individual has unprotected sex with an infected partner, there is a 70% chance that he or she will also become infected. In individuals with a history of previous HPV infection, the appearance of new<unk> s may be either from a new exposure to HPV, or from a recurrence of the previous infection. As many as one-third of people with<unk> s will experience a recurrence. Children Anal or<unk> s may be transmitted during birth. The presence of<unk> -like lesions on the<unk> s of young children has been suggested as an indicator of sexual abuse. However,<unk> s can sometimes result from autoinoculation by<unk> s elsewhere on the body, such as from the hands. It has also been reported from sharing of swimsuits, underwear, or bath towels, and from non-sexual touching during routine care such as diapering.<unk> s in children are less likely to be caused by HPV subtypes 6 and 11 than adults, and more likely to be caused by HPV types that cause<unk> s elsewhere on the body ("cutaneous types"). Surveys of pediatricians who are child abuse specialists suggest that in children younger than 4 years old, there is no consensus on whether the appearance of new anal or<unk> s, by itself, can be considered an indicator of sexual abuse.
