Sir: You state that homosexuals, along with drug users, are

'almost alone' in being at risk from Aids. It should be stressed that this statement applies only to male homosexuals; lesbians appear to be, in practice, immune. It is evident why this should be so and indicates that there is a curious hierarchy of risk among the sexual- ly active. What it means is that if you have to sleep with someone, it should always be a woman.
