AIDS (Acquired Immune Deficiency Syndrome) is a fatal disease that destroys the immune system. More than four out of five AIDS cases in the United States so far have been homosexual or bisexual men or drug users. Not all those who are infected with the AIDS virus, now 【C1】______one and a half million Americans, will 【C2】______ the disease, but scientists assume that 【C3】______ of the virus can spread it to others through sexual 【C4】______or exchange of blood or other bodily fluids. 【C5】______ about the spread of the disease has brought demands for testing to 【C6】______ evidence of infection. But proposals for testing have been 【C7】______ with a storm of questions and counterproposals from health officials, advocates of civil rights, and 【C8】______ fight activists. Should testing of people at special risk be 【C9】______ or mandatory(强制性的) ? How wide should testing be? What uses will be 【C10】______ of the results? If the secret is disclosed, is there a danger 【C11】______ people discovered be carriers will lose their jobs, housing, and access 【C12】______ public places? At a meeting in Feburary 1987, participants in a 【C13】______ sponsored conference on the control of AIDS 【C14】______ that testing should be voluntary and accompanied by safeguards to protect the 【C15】______ of those who are tested. The consensus,【C16】______ , was ruined by disagreements about definition of terms. One participant pointed 【C17】______ that 'mandatory' , ' routine'.'standard''required''and'confidential'were being used in different ways. As AIDS 【C18】______ more victims--by 1991health officials estimate that more than 50,000 Americans will die 【C19】______ AIDS each year public anxiety will mount and the demand for 【C20】______ testing and control may grow. State Laws written in the 1920s and 1930s to limit the spread of sexually transmitted diseases may not be adequate to protect against AIDS. But it remains unclear whether new laws requiting mandatory testing would produce sufficient health benefits to justify possible violations of civil rights. 【C1】
