Task: Question Answering
Input (English): Background Paragraph: While people have been able to prevent certain viral diseases by vaccinations for many hundreds of years, the development of antiviral drugs to treat viral diseases is a relatively recent development. Antiviral drugs are medications used specifically for treating the symptoms of viral infections. The first antiviral drug was interferon , a substance that is naturally produced by certain immune cells when an infection is detected. Over the past twenty years the development of antiretroviral drugs (also known as antiretroviral therapy, or ART) has increased rapidly. This has been driven by the AIDS epidemic. 
Story: The Doctor studied two teams of people. Team N had no viral infections, while Team W had many people with HIV among its members. Obviously, team N had fewer health issues. 
Question: Which team had fewer people receiving indirect benefits from the fight against the AIDS epidemic?
Output (English): team N.
