The Zimbabwe Population-based HIV Impact Assessment (ZIMPHIA), a household-based national survey, was conducted between October 2015 and August 2016. Preliminary results were announced in December 2016.

In Zimbabwe, the first country to conduct a PHIA survey, survey teams visited over 11,000 households, interviewed participants and provided HIV counseling and testing along with syphilis testing.

THIS offered HIV counseling and testing with return of results, collected information about household and individual characteristics and uptake of HIV care and treatment services.

The preliminary results were announced in December 2016 and the final report was released in August 2019.



Key Findings

HIV incidence among adults 15-64 years: 0.42%
HIV prevalence among adults 15-64 years: 14.1%
HIV prevalence among children 0-14 years:1.6%
Viral load suppression among adults 15-64 years living with HIV:59.6%
90-90-90 among adults living with HIV 15 years and older
(based on self-report and ARV detection data):
76.8% of adults living with HIV know their status;
88.4% of those individuals self-report being on anti-retroviral therapy (ART);
85.3% of those who report being on ART have viral load suppression.

The Economist: A report shows HIV in retreat in many African countries
The new data suggest that Africa is on the cusp of beating back HIV. But to do so it will have to redouble its efforts to educate, test and treat more people.

The Huffington Post: PEPFAR: Saving Lives And Changing The Course Of The AIDS Epidemic
We now have clear evidence from PEPFAR’s Population-based HIV Impact Assessments (PHIAs) that the epidemic is becoming controlled in older adults and babies in Malawi, Zambia, and Zimbabwe

Science: AIDS epidemic nears control in three African countries
This World AIDS Day, surprisingly good news came out of southern Africa, the region in the world that has suffered the most from HIV. A random household survey done of some 80,000 people in Zimbabwe found that more than 86% of the people on treatment had fully suppressed their virus.

Science: Southern Africa’s AIDS epidemic takes nosedive
The new data show that each of these three countries is approaching the UNAIDS 90-90-90 goal to control HIV/AIDS epidemics. UNAIDS modeling shows that epidemics will peter out if 90% of infected people know their HIV status, 90% of that group receive antiretrovirals, and 90% on treatment have undetectable viral levels.

UNAIDS: UNAIDS Welcomes Compelling Results of Progress in AIDS REsponse from Surveys Supported by the United States of America in Three Africa Countries
Upon the release of compelling new evidence of national AIDS programme successes in Malawi, Zambia and Zimbabwe, UNAIDS congratulates the countries as well as the United States of America for its consistently outstanding support to the global AIDS response.

ZimNews: ZIM AIDS Deaths Fall by 77% We Will Be Disease Free by 2030, says Mnangagwa
The VP said that according to ZIMPHIA Zimbabwe was making great strides in the fight against HIV and AIDS. "The new information from the survey will give the country information on new HIV infections, total number of people in need of treatment, and current levels of viral load."
