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, right approaches can and do result in lower national HIV infection rates / and less suffering for those affected by the epidemic.
