A SIMPLE THEORY AND A PROPOSAL ON H.I.V IN AFRICA

This piece of news said that in South Africa while around the world a vast majority of AIDS victims are men, Africa has long been the glaring exception because nearly 60 percent are women. And while there are many theories, no one has been able to prove one. The scientists think that they may have found a new explanation. It is far too soon to say the explanation is biologically plausible and if it is proved correct a low-cost solution has the potential to prevent thousands of infections every year. 

I hope that this are true because in the first world AIDS be in control but in the third world AIDS aren't be in control.
