Researchers at the University of Hong Kong of China and Albert Einstein College of Medicine in the United States concluded that the human papillomavirus, known as HPV, Kill people through sex 500,000 years ago.
The study, which was published by the journal PLOS Pathogens, explains that the virus evolved along with the ancestors of man and divided into two branches at the same rate as Neanderthal and Sapiens, about 80 thousand years ago.
"Understanding the evolution of papillomavirus should provide us important biological revelations and suggest new mechanisms by which human papillomavirus causes cervical cancer, "the findings state.
Scientists have explained that HPV is a group of microbes, of which There are 200 types, including 40 genitalia. In this latest scenario, they are contagious through sexual intercourse.
While in most cases, infections are cured in a few years, some patients may develop cervical cancer. This is the fourth most common among women: every year, there are 2,500,000 people dead all over the world. HPV can also cause rectal cancer, oral cancer, vulvar cancer and penis.
Researchers focused on the study the HPV 16 genome, the most common and deadly and other papillomaviruses present in non-human primates. In this way they were able to analyze – thanks to molecular watches – their diversity and the way they evolved.
The results showed that HPV viruses followed a "very early divergence model within the receptor, followed by a co-development between the virus and the host." That is, initially differentiated and then coexisted with each host.
Experts also pointed out that the presence of Subtype 16 in Asia shows that Neanderthals have transferred this virus to modern non-African people through reproductionas they moved east.
Vaccination campaigns
The Ministry of Health, along with the provinces, leads to a painstaking awareness campaign about the disease. The vaccine is free and compulsory for all 11-year-olds born after 2000. If the program started before the 14th, it is necessary to divide the two at least six months.
