Several months ago,I was planning to visit a friend who was in the hospital because of AIDS.(1)________________________.The doctor is a professor of medicine at New York University Medical center.He said, “You are more dangerous to him than he is to you,you might have a cold or some minor infection that would be very serious for him if he caught it,because he has no ability to protect himself.The risk to you is almost nonexistent.”(2)________________________________________.Though a great deal has to be learned about AIDS,our information is increasing quickly.Doctors now think they understand how it spreads,they can test whether someone has been exposed to the disease,and they know how to prevent its spread to others.(3)_____________________________________________.Indeed, the key to catching AIDS lies in two areas of contact.They are sex and sharing intravenous drug needles.But people can control them.Research indicates that worries of this sort are based on nothing.
I asked the doctor whether I should adopt any measures to protect myself.
it was only known several years ago and still as misfined to the public AID is frightening.
though the public attention has been focused on ? of casual contact with AIDS ? , medical authority disagree that disease is not easy to catch.
