Human waste should be hygienically disposed of. Human waste in water with the Oncomelania snail intermediate host is a major cause to the perpetuation of<unk> asis. To prevent this from occurring, human waste should never be used for nightsoiling (fertilization of crops with human waste) and unsanitary conditions should be improved. To avoid infection, individuals should avoid contact with water (including swimming and walking through water) that is contaminated by human or animal waste, especially water sources that are endemic to Oncomelania snails. Other important prevention techniques include: drinking purchased mineral water from stores and boiling water on high temperature for at least one minute before it would be used for drinking or bathing. Iodine treatment does not guarantee the safety of the water. If necessary to enter potentially infected water, cercarial repellents and cercaricidal ointments can be applied to the skin before entering the water. Barrier cream with a dimethicone base offered high levels of protection for at least 48 hours. The search for a practical vaccine continues and could greatly benefit affected areas.
