Sightsavers works on a range of programmes to prevent blindness, advocate for disability rights, and fight neglected tropical diseases. It improves children’s lives and future prospects by treating two neglected tropical diseases — schistosomiasis and intestinal worms — with an intervention sometimes known as “deworming.”
Schistosomiasis and intestinal worms are two parasitic diseases found mainly in tropical and subtropical climates — particularly in poor communities without access to safe drinking water and sanitation — that have a detrimental impact on children’s nutrition, health, and education.
According to the World Health Organization, 1.5 billion people worldwide are infected with intestinal worms, and 600 million school-aged children live in at-risk areas. Intestinal worms can cause a variety of health problems, including nutritional issues and problems with cognitive and physical development.
Schistosomiasis affects 240 million people worldwide, with more than 700 million people living in endemic areas. Schistosomiasis can “lead to serious long-term problems affecting the digestive, urinary, respiratory and nervous systems.” It is estimated that as many as 200,000 people die from schistosomiasis every year.
Both diseases can also affect social and economic outcomes, like employment and school attendance.
As part of its deworming programme, Sightsavers:
Sightsavers reports that in the last project year (2021 to 2022), it treated more than 5.6 million children for schistosomiasis and/or intestinal worms.
