The UNAIDS 2016–2021 Strategy is a bold call to action to get on the Fast-Track to end the AIDS epidemic by 2030 and reach people being left behind. It is a call to reach the 90–90–90 treatment targets, to close the testing gap and to protect the health of the 22 million people living with HIV who are still not accessing treatment. It is a call to redress the deplorably low treatment coverage for children living with HIV. A new 2021-2030 UNAIDS Strategy is currently under development, with updated HIV targets and estimates of resources needed. 

Since 2010, new HIV infections among children have declined by 52%. AIDS-related deaths have been reduced by 60% since the peak in 2004, with 690,000 people dying from AIDS-related illnesses worldwide, compared to 1.7 million people in 2004.

In 2019, in partnership with the Global Fund, World Vision ensured 20.1 million people received antiretroviral therapy for HIV.

Tuberculosis (TB) is a treatable and curable disease, but remains the world's biggest infectious killer, with 1.4 million people dying of TB in 2019. TB is the leading killer of people living with HIV, causing one in three deaths. World Vision staff are committed to treating and identifying TB in the communities where we work. In partnership with the Global Fund to fight AIDS, Tuberculosis and Malaria, World Vision has implemented over 40 TB grants, helping to strengthen community systems that work to train community health workers, social workers, doctors and others who work directly with TB.

Communities that are most vulnerable - including children under five years old, pregnant women and those already affected by HIV and AIDS - are more susceptible to malaria. Prevention and treatment for malaria is integrated into World Vision's global health strategy. This means that, in areas where malaria is an issue, we work to assure that families – especially mothers and children under age 5 – are sleeping under a long-lasting insecticide treated bed net. We also work to strengthen health systems to make sure families have access to proper diagnosis, treatment and care. Through our water, sanitation and hygiene interventions, we work to prevent the issues that create breeding grounds for malaria-carrying mosquitoes. In 2020, with funding from the Global Fund, World Vision brought life-saving malaria prevention and treatment to more than 22.2 million people in six countries and distributed more than 13.8 million long-lasting insecticide-treated bed nets in three countries.

World Vision is a part of the CORE Group Polio Project, a multi-country and multi-partner initiative that supports organisations in working together towards eradicating polio through financial assistance and on-the-ground technical guidance. The CGPP works to improve vaccine uptake for polio and other vaccine-preventable diseases such as measles, conducts surveillance for infectious disease threats, and strengthens health systems. World Vision has partnered with the CGPP in Angola, Bangladesh, Ethiopia, India, Kenya and South Sudan.

"Core Polio is a testament to civil society's role in public health, and collective action. It is amazing really that the world does not do better to celebrate seminal achievements like the elimination of polio. It is the kind of story that gives us hope for a better future." 

Dan Irvine, Senior Director, Health and Nutrition, World Vision International

The Ebola outbreak across West Africa between 2014 and 2016 was the largest and most complex since the virus was initially discovered in 1976 (WHO). Additional outbreaks followed, with the Democratic Republic of the Congo (DRC) facing the second largest Ebola outbreak in history from 2018 to 2021. 

World Vision continues to work in communities that survived the Ebola crisis, and in communities that are still dealing with outbreaks of Ebola today. The health emergency response team reached 1.6 million people during the epidemic that took place in Sierra Leone. 

Working with World Vision's Channels of Hope Team, community health workers and faith leaders found ways to fight the epidemic and create awareness about the disease in order to avoid fatalities. Furthermore, World Vision continues to work with the faith leaders to bring hope to the families and communities that have been affected by the tragedy. Read more here.

World Vision was chosen to be a part of an initiative to bring an Ebola vaccine solution to West Africa as a member of the Ebola Vaccine Deployment, Acceptance, and Compliance (EBODAC) consortium, that worked in four countries Democratic Republic of the Congo (DRC), Rwanda, Sierra Leone and Uganda to develop strategies and tools to promote the acceptance and uptake of new Ebola vaccines, so the right persons would receive the right vaccine at the right time. EBODAC (2014 to 2021) used phone messaging, as well as clear communication methods to build trust and address misconceptions surrounding the vaccine in the community. EBODAC also built local knowledge and capacity and strengthened health systems by working with ministries of health and community health workers by providing training and preparedness activities for the potential future deployment of a licensed vaccine.


The Zika Virus, transmitted by the Aedes Aegypti mosquito, was first detected in Brazil in May 2015. One great concern is that the newborns, of pregnant mothers who were infected by the disease, can suffer from microcephaly, a congenital condition that causes incomplete development of the brain. 

Zika response

Since the outbreak, World Vision has been working directly with the countries who have been affected by providing services and resources necessary for disease-prevention. Mosquito nets and bug repellants have been provided to communities, along with health services for pregnant women and others who have contracted the virus. To learn more about the Zika Virus, listen to a webinar that provides an overview of the virus and the health strategy towards fighting the disease and learn how community volunteers and smartphones helped to reveal dangerous gaps
