Summary Introduction
To determine: Whether “drug holiday” during multidrug treatment for AIDS is a good or bad idea.
Introduction: Acquired immunodeficiency syndrome (AIDS) is a life-threatening disorder that is caused by a retrovirus called human immunodeficiency virus (HIV). This is a life-threatening syndrome because the virus interferes with the body’s ability to fight against diseases by destroying T cells of the immune system. Azidothymidine (AZT) is the common drug that is used in delaying the development of AIDS in those individuals who are infected with HIV.

- As people use more of an antibiotic, the number of bacteria that are resistant to that antibiotic increase. Which statement describes a mechanism behind this trend? (A.) People’s bodies become more resistant to antibiotics after exposure to them (B.) Antibiotic molecules get weaker over time due to natural selection (C.) The antibiotic kills sensitive bacteria, and any bacteria resistant to it multiply to take their place (D.) Bacteria take up antibiotics and integrate them into their own DNAarrow_forwardAntibiotics are a form of medicine used to treat bacterial infections. However, new bacteria are evolving that are resistant to antibiotics. When someone uses antibiotics, they often contribute in a small way to an increase in the number of bacteria that are resistant to antibiotics. How would an economist classify antibiotic use? Public health officials are concerned with the overuse of antibiotics, which leads to bacteria being resistant to antibiotics.
