8 Horrible Infectious Diseases Humanity Has Triumphed Over

Guinea Worm

Guinea worm disease (GWD), also known as Dracunculiasis is an infectious disease that affects a person who drinks water that contains fleas infected with guinea worm larvae. At first, people who suffer from this disease show no symptoms, but after a year the female worm starts to develop, causing a lot of symptoms. 

According to some statistics, there were about 3.5 million cases of Guinea worm disease in 1986 in South Asia, Yemen and sub-Saharan Africa. Scientists have developed some water purifiers to prevent the spread of this disease and it worked. For instance, in 2018, there were only 28 cases of dracunculiasis.
