ZAMPHIA is a scientific assessment of the progress made against HIV/AIDS in Zambia. It is also helping expand HIV prevention measures and assisting those who test positive to obtain the treatment they require. 


The ZAMPHIA survey is an example of what is known as a population-based HIV impact assessment, or PHIA. PHIAs have been conducted across Africa with technical assistance from the US Centers for Disease Control and Prevention (CDC).


To find out more about PHIAs, and what has been done in the larger PHIA context, read this bulletin from the CDC, entitled “New PHIA Survey Data Show Critical Progress Towards Global HIV Targets.” 

ZAMPHIA staff have been reaching out in communities to help set the record straight and facilitate greater knowledge of the survey. There are still many unanswered questions, and we have assembled these FAQs and other materials to help clear up the confusion.

NOTICE: The ZAMPHIA Survey's field-based activities will begin in the second quarter of 2021. The activities will be implemented under strict adherence to COVID-19 guidelines. Please stay safe.
