Schistosomiasis is a neglected tropical disease affecting approximately 240 million people, mostly in sub-Saharan Africa. The condition is caused by the Schistosoma parasite, of which the larval stage (cercaria) penetrates the human skin when in contact with infested water. During its lifecycle inside the human body, the parasite produces eggs which are then, depending on the species, expelled by urine or feces. Detecting the eggs from feces or urine by microscopy is one of the main diagnostic techniques. However, the number of eggs in excreta may be extremely low. Consequently, low-intensity infections are easily missed. Centrifugation of large urine volumes or filtration through a filter can increase the diagnostic sensitivity, but this is a more labor intense procedure. The S. haematobium eggs are 110-170 µm long and 40-70 µm wide.
