You might know Ryan Lewis for his work with Macklemore on hit songs like "Thrift Shop" and "Can't Hold Us." In addition to being an award winning musician, Lewis is busy working to bring quality and affordable healthcare to those who need it most.

It is an issue close to his heart. Ryan Lewis' mother Julie was infected with HIV through a blood transfusion while giving birth 30 years ago. The 30/30 Project is marking her three decades of survival by raising money to build health centers around the world that will provide care for at least the next 30 years.

Anderson Cooper spoke with Ryan and Julie Lewis about the impact HIV has had on their family.
