Hans Rosling, a professor of global health at Karolinska Institut, focuses on dispelling common myths about the so-called developing world and its relationship with HIV/AIDS.

In Hans Rosling’s TED Talk, he used very interesting and vivid graphs to explain how HIV spread throughout the past twenty-five years. The rate of those effected by HIV is not about poverty and undeveloped, although there are many reasons why one’s living conditions makes one more susceptible to the virus. An often understated fact, Rosling notes that even countries with a good economy and peaceful environment may be hard to drop the population of HIV-infected persons, because with good healthcare, HIV carriers can live ten to twenty years longer than those living in places with less access to effective healthcare.
