AIDS was first recognized as a disease in 1981. During the two decades since
that discovery, there has been continuing controversy as to the cause of this
illness and thus to the appropriate treatment and prevention strategies.

Your assignment is to read the following web sites that argue both sides of the
issue and then write an editorial supporting your point of view.



You may support either side or argue that we need more information. Provide the
data/evidence that you think is most compelling and indicate what actions in the
fight against AIDS should be taken based on your position and what the
consequences of supporting the opposing positions would be. You may use other
resources if you wish.

This editorial must be typed. It should be no longer than one page. Spelling and
grammar count. Please identify yourself only by your student ID.
