Schistosomiasis, also known as bilharzia, is a disease caused by parasitic worms. More than 200 million people are infected worldwide. In terms of impact this disease is second only to malaria as the most devastating parasitic disease. Schistosomiasis is considered one of the Neglected Tropical Diseases (NTDs).
All people are at risk from cryptosporidiosis. It is caused by a protozoan parasite that is shed in the feces of domestic animals and humans, causing profuse watery diarrhea and abdominal cramping. It can also be accompanied by nausea, loss of appetite, headache and fever.
Experts estimate that between 30 million and 100 million people are infected with Strongyloides worldwide, and most of them are unaware of it because their symptoms are so mild. The parasite can persist for decades in the body because of the nematode’s unique ability to reinfect the host, repeatedly going through the early stages of its life cycle.
Malaria is a mosquito-borne disease caused by a parasite. People with malaria often experience fever, chills, and flu-like illness. Left untreated, they may develop severe complications and die. In 2016 an estimated 216 million cases of malaria occurred worldwide and 445,000 people died, mostly children in the African Region.
