New PHIA Survey Data Show Critical Progress Towards Global HIV Targets
New findings released today by the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR), CDC and ICAP at Columbia University from the Population-based HIV Impact Assessments (PHIA) show that country, global, and US-supported HIV efforts have made critical progress toward achieving an AIDS-free generation.
Combining household visits with key questions and cutting-edge technologies, PHIA surveys are the first to directly measure all of the above: national HIV incidence, pediatric HIV prevalence, and HIV viral load suppression in some of the countries most affected by the HIV epidemic. Under the leadership of each country’s Ministry of Health, survey teams travel door to door to implement these surveys in 13 PEPFAR-supported countries mostly in Sub-Saharan Africa – the region that is most severely impacted by HIV. These countries include: Cameroon, Cote d’Ivoire, Ethiopia, Haiti, Kenya, Lesotho, Namibia, Malawi, Swaziland, Tanzania, Uganda, Zambia, and Zimbabwe. PHIA survey results from each country will become available as they’re completed over the next few years.

The new findings also validate what have only previously been predicted in models: that global HIV efforts are accelerating country progress toward achieving epidemic control. They also shine a light on the specific populations that need greater attention and services to meet their needs. Specifically, they show us that more attention is needed to reach more young people with HIV, especially adolescent girls and young women, to help them stay on their treatments. More work is also needed to reach adult men with HIV testing since they are less likely than women to know their status.
In collaboration with partners, CDC’s Division of Global HIV & TB is playing a key role in designing and implementing the PHIA surveys — lending expertise in epidemiology, laboratory science, program services, and workforce training. The surveys will provide critical information on the state of the HIV epidemic and help shape future HIV policies and programs.
Statement from Shannon Hader, MD, MPH, Former Director of CDC’s Division of Global HIV & TB
“The Population-based HIV Impact Assessments are a powerful new tool in that they paint the clearest picture to date of the HIV epidemic in several sub-Saharan countries. New findings from Malawi, Zambia, and Zimbabwe validate what we have only been able to previously predict in models – that our global efforts are having a measurable impact in countries with some of the most severe HIV epidemics.
These data suggest that, in the areas surveyed, we are making encouraging progress towards global targets for people on HIV treatment and virally suppressed.
At CDC, saving lives through public health impact is our core mission. We believe data is a foundation that helps us do that more effectively. These surveys allow us to harness the power of data for greater insights on where to focus our collective efforts and resources going forward. This ultimately helps save more lives.
The Population-based HIV Impact Assessments would not have been possible without the leadership and support from the country governments and ministries of health, funding and support from the U.S. President’s Emergency Plan for AIDS Relief, technical expertise and implementation supports from ICAP at Columbia University and our CDC experts on the ground in collaboration with local partners.”
Stories from the Field
CDC is playing a key role in providing technical and scientific expertise to country partners in creating and implementing the PHIA surveys to mark progress and inform next steps to save more lives. Following are brief profiles that highlight different approaches countries are taking to bring PHIA surveys to communities nationwide:

The Malawi population-based HIV impact assessment was led by the Government of Malawi through the Ministry of Health, conducted with funding from the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) and technical assistance through the U.S. Centers for Disease Control and Prevention (CDC). The survey was implemented by ICAP at Columbia University in collaboration with local partners.
Singing the praises of Zimbabwe
Zimbabwe was the first country to launch the population-based HIV impact assessment (PHIA). The PHIA is the first household survey in Zimbabwe to directly measure national HIV incidence, pediatric HIV prevalence, and viral load suppression, and use of services. The survey provides the sharpest picture to date of the HIV epidemic in the country. In Zimbabwe, survey teams visited approximately 15,000 households across the country to interview consenting participants and provide them with HIV counseling and testing, as well as syphilis testing.
In Zimbabwe, the song, “Knock, Knock, Knock,” was recorded by leading Zimbabwean poets and musicians to share the importance of the PHIA surveys with communities across the country. The song played frequently on the radio and reached cities and rural areas helping to inform communities about the house to house surveys that were happening across the country. “The ZIMPHIA song is a great example of the creative, collaborative approaches to public health promotion that CDC likes to support,” said Beth Tippett Barr, CDC Country Director, Zimbabwe. “It reflects a strong engagement with our national partners.” The success of the effort was evidenced by the nearly 12,000 people who participated in the survey from 2015-2016. Zimbabwe’s creativity and success to date in effectively responding to the HIV epidemic is a model for others working to pave the way toward an AIDS-free generation.

Supporting the next generation of HIV surveillance in Zambia
CDC began work in Zambia in 2000. The country had previously implemented many strategies to address the HIV epidemic, but there was not enough quality data to guide national decision-making and planning. For almost a decade, CDC has worked with the Zambian government and multilateral donors to improve disease surveillance throughout the country. CDC’s earliest involvement was through surveillance which focused on sentinel surveillance and AIDS cases.
Most recently, CDC has been providing technical support to the Government of the Republic of Zambia to establish the next generation of disease surveillance. These surveys focus on improving and expanding existing surveillance methods and include bio behavioral, HIV-case, sexually transmitted infection (STI) and morbidity and mortality surveillance. One example of these surveys is the Zambia population-based HIV Impact Assessment (ZAMPHIA)External
CDC Zambia is excited about the potential of working alongside our partners to bring together these surveillance strategies to better serve the needs of the country and address the HIV epidemic. The Zambia population-based HIV impact assessment was led by the Government of Zambia through the Ministry of Health, conducted with funding from the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) and technical assistance through the U.S. Centers for Disease Control and Prevention (CDC). The survey was implemented by ICAP at Columbia University in collaboration with local partners.

PHIA surveys are one part of CDC’s broader efforts, through PEPFAR, to ensure people with HIV know their status, are linked to treatment, and are virally suppressed – with the ultimate goal of preventing new infections and saving more lives.
