title: Pit latrine
context: A pit latrine, also known as pit toilet or long drop, is a type of toilet that collects human feces in a hole in the ground.[2] Urine and feces enter the pit through a drop hole in the floor, which might be connected to a toilet seat or squatting pan for user comfort.[2] Pit latrines can be built to function without water (dry toilet) or they can have a water seal (pour-flush pit latrine).[7] When properly built and maintained, pit latrines can decrease the spread of disease by reducing the amount of human feces in the environment from open defecation.[4][8] This decreases the transfer of pathogens between feces and food by flies.[4] These pathogens are major causes of infectious diarrhea and intestinal worm infections.[8] Infectious diarrhea resulted in about 700,000 deaths in children under five years old in 2011 and 250 million lost school days.[8][9] Pit latrines are a low cost method of separating feces from people.[4]
