问题     On the surface, AIDS appears to have barely touched Asia so far, and the few cases reported involve mainly foreigners, female and male prostitutes (妓女) and imported blood. But complacency could be a fatal error. Experts have no doubts that the reported cases represent only the tip of an epidemic iceberg; many more people are infected than cases reported, in part because the virus takes five to seven years from infection to develop into AIDS.
    Says Dr. Jonathan Mann, director of the Special Program on AIDS of the World Health Organization: "AIDS is knocking on the door of Asia. "
    Yet because AIDS is occurring later in Asia than in other continents, Asians can benefit from the knowledge gained at a heavy price elsewhere: AIDS can be transmitted through heterosexual as well as homosexual contact and prevention through education is the key—indeed the only—defense so far available. In the words of Dr. Mann, "the opportunity for protection of Asia against widespread dissemination of HIV"—the AIDS virus—"is obvious and may be vital to the future of the continent. "
    In contrast to Asia, Africa had no warning at all when the disease began to appear there. Today, several million men, women and children may already be affected. Here is a Reader’s Digest report on the African crisis, followed by detailed information on AIDS and how it can be prevented.
It can be inferred from the passage that______.

选项 A、nothing had been known of AIDS before it was found in Africa
B、Asians have suffered little as they all have good education
C、foreigners in Asia may be the most vulnerable to AIDS
D、other continents will fall victims of AIDS very soon
