The United Nations on Saturday announced a new campaign to dramatically increase the number of people on HIV antiretroviral treatment by 2015.

The program, titled Treatment 2015, aims to combat HIV by increasing the number of people on antiretroviral treatment from 10 million to 15 million in 2 years.

“Reaching the 2015 target will be a critical milestone,” said Michel Sidibe, executive director of the Joint UN Programme on HIV/AIDS (UNAIDS). “Countries and partners need to urgently and strategically invest resources and efforts to ensure that everyone has access to HIV prevention and treatment services.”

Ambassador Eric Goosby, who currently serves as the United States global AIDS coordinator, said increasing access to antiretroviral treatment is critical to achieving the goal of zero new infections. People on the therapy have decreased viral loads, making them far less likely to infect others.

Officials are focusing their efforts in 30 countries which account for 9 out of 10 people who are in need of antiretroviral therapy but who currently do not have access. Those countries include Angola, Brazil, China, Cameroon, Central African Republic, Chad, Colombia, Cote d'Ivoire, Democratic Republic of the Congo, Ethiopia, Ghana, India, Indonesia, Kenya, Lesotho, Malawi, Mozambique, Myanmar, Nigeria, Russian Federation, South Africa, South Sudan, Thailand, Togo, Uganda, Ukraine, United Republic of Tanzania, Vietnam, Zambia and Zimbabwe.
