答案 AIDS When AIDS first emerged, /no one could have predicted how the epidemic would spread across the world /and how many millions of lives it would change. /There was no real idea what caused it/ and consequently no real idea how to protect against it. /Now we know from bitter experience/that AIDS is caused by the virus HIV, /and that it can destroy families, communities and continents. /However, experience has also shown us that the right approaches can and do result in lower national HIV infection rates/ and less suffering for those affected by the epidemic.
