CDC on the Frontlines: The Leaders, Experts, Innovators, and Change Makers Transforming the Global HIV Epidemic

Since its launch, the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) has helped save more than 17 million lives. As a key implementing agency of PEPFAR, CDC is at the forefront of the global response to HIV – bringing scientific know-how and on-the-ground expertise to bear in the fight against one of the world’s deadliest infectious diseases. At CDC, the core of our expertise is our people – the experts, partners and changemakers transforming the global HIV epidemic. These are their stories – and their impact.

Global Health Security Agenda

In today’s tightly connected world, a disease threat anywhere is a disease threat everywhere.

The Global Health Security Agenda (GHSA) is a global effort to strengthen the world’s ability to prevent, detect, and respond to infectious disease threats. Over the course of the first 5 years of GHSA implementation, CDC-supported countries have strengthened public health readiness to contain outbreaks at their source. Threats remain, and sustained focus on global health security is critical to protecting the United States and the world from dangerous diseases and outbreaks.

Neglected Tropical Disease Day

The impact of mass drug administration and progress towards elimination of lymphatic filariasis (LF), a debilitating neglected tropical disease (NTD), is measured by community surveys. CDC was instrumental in developing the World Health Organization’s (WHO’s) monitoring guidelines for LF elimination efforts and has been providing technical assistance around the world ever since.

CDC Tanzania: Working Together to Save Lives

The Centers for Disease Control and Prevention (CDC), under the U.S. Mission to Tanzania, established an office in 2001 to support HIV/AIDS prevention, and expanded through the U.S. President’s Emergency Plan for AIDS Relief in 2003. CDC works in Tanzania to strengthen tuberculosis prevention efforts for people living with HIV; enhance laboratory, surveillance, and workforce capacity to respond to disease outbreaks through the Global Health Security Agenda; and implement interventions for malaria prevention and control under the U.S. President’s Malaria Initiative.

CDC Around the World

World Tuberculosis Day

CDC has been working around the world for more than 60 years.

Disease knows no borders. In today’s interconnected world, diseases can spread from an isolated, rural village to any major city in as little as 36 hours. The U.S. cannot protect its borders and the health of its citizens without addressing diseases elsewhere in the world. CDC works 24/7 to protect Americans and save lives around the world by detecting and controlling outbreaks at their source. In addition, CDC helps other countries increase their ability to prevent, detect, and respond to health threats on their own.
