Men have genital human papillomavirus (HPV) are at increased risk of reinfection with the same HPV type, according to a study published in the journal PNAS.
After analyzing the data of over 4 thousand men who are not vaccinated against HPV, in Florida, Mexico and Brazil from 2005 to 2009, the researchers also found that among men infected with HPV type 16, the risk of re-infection in a year has increased 20 times in two years – 14 times.
The results were also relevant for sexually active men and for those who are not married, which suggests that men re-acquire the virus from another sexual partner, said the researchers from University Medical center Chicago.
The study highlights the importance of vaccination to prevent the spread of HPV in young people before they become sexually active. Vaccination can potentially prevent the occurrence of reinfection in men of older age who has already contracted the virus.
“Vaccination of boys prior to exposure to HPV can be an effective way to reduce the burden of HPV infection. Vaccination of men who have already been infected, it can also be effective,” said the authors.
As you know, there are more than 200 types of HPV. The study authors noted that vaccination protects against four to nine of the most common types that cause the development of diseases.
