A notícia, que podemos ler na BBC, dá conta dos resultados de investigações de cientistas franceses. Dizem estes que os povos que hoje vivem em ex-colónias governadas por Roma têm menos probabilidade de desenvolver um gene protector da sida:
"In countries inside the borders of the empire for longer periods, such as Spain, Italy and Greece, the frequency of the CCR5-delta32 gene, which offers some protection against HIV, is between 0% and 6%.
Countries at the fringe of the empire, such as Germany, and modern England, the rate is between 8% and 11.8%, while in countries never conquered by Rome, the rate is greater than this."

Não se pode dizer que não são observações engraçadas, mas há quem tenha outra teoria (com menos piada): "Others argue the difference is linked to a far larger event, such as the spread of bubonic plague or smallpox."
