Against Malaria Foundation Deworm the World GiveDirectly Schistosomiasis Control Initiative Malaria Consortium Hellen Keller International


A$ 100 to Schistosomiasis Control Initiative can

Protect 185 children from schistosomiasis for one year.

The Organization

Worms and other parasitic and bacterial Neglected Tropical Diseases (NTDs) affect two billion people worldwide, most of whom live on less than $2 a day. The most deadly of these is schistosomiasis, which the WHO estimates is responsible for 200,000 deaths a year. Another 300 million, roughly the population of the United States, suffer from severe illness, and half of those are school-aged children. NTDs are responsible for a range of serious health problems from malnutrition, to impaired cognitive development, to blindness. They can increase the morbidity and mortality of malaria, tuberculosis and HIV/AIDS, and infected children are often too sick to attend school. Schistosomiasis Control Initiative (SCI) works with governments across sub-Saharan Africa to create or scale up mass school-based deworming programs, which have a strong track record of success. These programs provide school children with pills that protect against the most prevalent NTDs.

The Numbers

GiveWell estimates that the cost per child treated through SCI's programs is AUD 0.54, although this price doesn't include the government contribution to the program or the cost of the drugs, which are usually donated by the manufacturers. There is evidence that mass-deworming programs improve educational outcomes and children's future earning potential. A recent study from the Harvard School of Public Health found that students in deworming treatment areas performed better on literacy and numeracy tests as compared with other students 7-8 years after the end of their deworming treatment. A thorough discussion of the strengths and weaknesses of the evidence behind deworming can be found here.

GiveWell, widely considered the most rigorous charity evaluator in the world, recommends SCI as one of their top charities based on their cost-effectiveness and transparency.


Our Process

We designed this Impact Calculator to help answer the first question on a donor’s mind: where does my money go? While it’s easy to focus on overhead percentages, the real impact of a charity is reflected in what that charity can do with its budget. A donor who cares about reducing extreme poverty has hundreds of organizations to choose from – some of which are thousands of times more effective than others. Our Impact Calculator highlights the work of a few of the world’s most effective charities, allowing you to compare each organization – and the evidence supporting each intervention – side by side.

Effective Altruism Australia’s objective is to help others as much as possible for every dollar donated. To do this we support charities that are consistently ranked as highly cost effective by independent charity evaluators such as GiveWell, Giving What We Can, and The Life You Can Save. Because of their focus on transparency, commitment to evaluation and follow-up, and scaling of proven interventions, we have high confidence that these charities can reliably transform the lives of the worst off.

Determining a charity’s cost-effectiveness can be a complicated endeavor, and we could never hope to reflect our recommended charities’ full impact in one simple online tool. Instead, we’ve tried to create a starting point you can use in order to kickstart your investigation into impact-oriented philanthropy. We encourage you to use this as one resource among many in your charity assessments.
