Can you be reinfected with hpv

So, buckle up. HPV is a particular type of virus that is transmitted by skin-to-skin contact. It is known primarily as a sexually transmitted disease — through vaginal, anal, oral, and non-penetrative sex — but it is not only transmitted sexually. One of the difficulties with the virus is that it is not actually a single virus at all. The former are those associated with genital warts, whilst it is the latter group that have the potential to lead to cancer. They tend to change the way that cells multiply, for example, and, if cells replicate uncontrollably, they can develop into tumours.

However, this does not happen to everyone. The rest may not experience any symptoms at all. As such, the majority of people with HPV infections will not even know that they have it. In this respect, there is a bit of good news: HPV infections tend to clear naturally by themselves. One influential clinical trial showed that this tends to happen within a period of two years. While this is testament to the power of our immune systems, it also comes with two drawbacks.

Firstly, those of us who cannot manage to clear the infection in two years appear to be more likely to develop cancer. And secondly, the fact that many people do not know they have the virus means that it is often spread to their sexual partners. HPV virus does not come back once it has cleared — and it is very unlikely that you will catch the same type of HPV if you have had it.

Again, though, these should clear naturally. If you have genital warts, however, these can come back after treatment. Even if you successfully remove the warts themselves, this does not mean that the virus itself has disappeared. Only when the HPV has been cleared will the warts stop recurring. Just to note, by the way, if you have warts in the genital area, you are at no greater risk of HPV-related cancers. These are caused by separate strains of the virus.

There is a little bit more bad news about HPV. Viruses in general, like covid or influenza, are notoriously difficult to manage. And this is in large part because they are not strictly alive , so cannot really be killed. The most powerful tool that is used in the fight against HPV is the vaccination. Men who have sex with men are also eligible to have the vaccination up until the age of The vaccine that is used is called Gardasil, and this protects against HPV types 6, 11, 16, and Approximately 40 percent of women and 45 percent of men in the United States are infected, and it is a major cause of genital warts and cancers of the genitals, mouth and throat.

There are more than genetically-distinct HPV types; vaccines protect against four to nine of the most common, disease-causing types. Ranjeva and her UChicago colleagues, including Greg Dwyer , PhD, professor of ecology and evolution and Sarah Cobey , PhD, assistant professor of ecology and evolution, wanted to understand what allowed so many different types of HPV to coexist. They analyzed data regarding the spread of the disease from the HPV in Men study, which tracked more than 4, unvaccinated men from three cities in Florida, Mexico and Brazil over five years from to Usually, diversity of so many types of viruses happens as they compete to evolve different ways to evade the immune defenses of hosts.

The new analysis showed no evidence of such competition among HPV types, however. Instead, the diversity of HPV types may stem from recurring infections of particular types within individuals. While relatively few people are infected with any one type, the high overall HPV prevalence occurs because nearly half the adult population carries at least one type of genital HPV. The high risk of reinfection may be due to either auto-inoculation, spreading the infection by repeated contact between different sites on the body, or reactivation of a latent virus.

The results also show that men who are infected once with HPV16, the type responsible for most HPV-related cancers, are at 20 times higher risk of reinfection after one year, and 14 times higher after two years. The researchers saw the same effect in both men who are sexually active and celibate, suggesting that they are not reacquiring the virus from another sexual partner.

However, if the increased risk of reinfection is due to auto-inoculation, then another effective strategy may be to vaccinate previously infected men as well.

However, studies show that in most cases a healthy immune system will be likely to clear, or suppress, HPV eventually.

Some cases may persist for years and result in recurrent lesions, but this is not the norm. The bottom line is that most who have genital HPV DNA detected in research studies eventually test negative, often within a year or two. Still, HPV does not seem likely to always be active. Skip to content. Talking to a Partner Before discussing things with a partner think about addressing any of your own questions or issues about HPV.

This is why it is usually impossible to determine when or from whom HPV may have been contracted. A recent diagnosis of HPV does not necessarily mean anyone has been unfaithful, even in a long-term relationship spanning years. Medical Impact: The medical risks of genital HPV do exist and should not to be overlooked, but a key point is that for most people, HPV is a harmless infection that does not result in visible symptoms or health complications.

In some cases, HPV may cause cell changes that persist for years, and the cells can eventually become cancerous if not detected in time. However, regular screening such as Pap tests can almost always find abnormalities so they can be treated, if needed, before cancer occurs.
