Researchers at the University of Hong Kong, China and Albert Einstein's medical medical school in the United States have found that a papiloma virus known as HPV, Kill people with sex 500,000 years ago.
A study published by the magazine PLOS pathogens, explains that the virus developed along with human ancestors and was divided into two branches at the same rate as Neanderthals and sapiens departed about 80,000 years ago.
"Understanding the evolution of the papilloma virus must bring us important biological disclosures and suggest new mechanisms by which human papillomavirus can cause cervical cancer, "described in the conclusions in more detail.
Scientists have explained that the HPV virus consists of a group of microbes from which There are 200 species, 40 of which are infected by genitalia. In this last scenario, they are infectious with sexual contact.
While in most cases infections are recovering in a few years, some patients may develop cervical cancer. This is the fourth most common among women: every year, 2,500,000 people die worldwide. HPV can also cause anus cancer, oral cancer, vulvar and penis cancer.
Researchers focused on studying the genome of the HPV 16 virus, the most common and deadly and other papilloma viruses, present in primates other than humans. In this way, thanks to molecular hours, their diversity and how they developed.
The results showed that HPVs followed "a very early divergent model within the host, followed by co-evolution between the virus and the host." This means that they were originally diverse and then co-existed with each host.
Experts also emphasized that the presence of subtype 16 in Asia indicates a Neanderthal he transmitted this virus to modern non-African peoplewhen they moved east.
The Ministry of Health together with the provinces is leading a difficult campaign to raise awareness of the disease. The vaccine is free and compulsory for all girls aged 11 years and born after 2000. If the scheme started before 14, it is necessary that the two be separated for at least six months.
