The sport “Schisto & Ladders” is launched to college students in an elementary college in part of Nigeria the place the uncared for tropical illness schistosomiasis, unfold by parasitic worms, impacts many residents. This model of the basic “Chutes & Ladders” video games goals to show youngsters easy methods to keep away from getting contaminated — and particulars of the therapy for individuals who catch it.

Chutes & Ladders has been a beloved board recreation within the U.S. because the Nineteen Forties — tailored from an historical Indian recreation that aimed to show ethical classes.
Youngsters in Nigeria are actually enjoying a model known as “Schisto & Ladders.” It too goals to show — about easy methods to stop a illness known as schistosomiasis. It is a parasitic
an infection attributable to a worm that infects people by way of pores and skin contact with infested waters.
An unfortunate participant may land on a sq. that claims “enjoying in a river” That places you in danger for this tropical illness — and sends your recreation token down a worm as a substitute of a chute.
Nigerian researcher and educator Cynthia Umunnakwe is among the builders of the sport — it is a part of an arsenal of inventive approaches to averting the sickness. Identified regionally at “Atosi Aja” or Bloody Urine, the illness not solely causes blood within the urine however has different short-term signs akin to fever and rash. If untreated, it will probably trigger main organ and neurological harm, infertility and even bladder most cancers. In Nigeria, it’s related to greater charges of bladder most cancers in younger folks.
Referred to as a Uncared for Tropical Illness due to the shortage of funding to combat it, schistosomiasis is a critical problem for impoverished communities. There are over 200 million instances throughout sub-Saharan Africa. Faculty age youngsters are on the biggest threat of an infection as a result of they wish to play within the water and their immune programs aren’t totally developed.

Although efficient treatment exists, the problem is persistent in areas with a scarcity of quick access to testing, therapy and clear water so folks do not depend on native our bodies of water for consuming and bathing. Consciousness of its transmission can also be a problem. Touching infested water, even only a splash, can threat an infection, as microscopic larvae swimming alongside the floor are capable of wriggle by means of pores and skin.
Uh oh, a worm!
The sport, created in 2014 by a workforce led by Professor of Parasitology Uwem Ekpo of Akwa Ibom State College, follows the basic sample: Roll a cube to advance up a winding path to the highest of the colourful board. A participant may land on a sq. that sends them up a ladder or sliding down a Schisto worm (which takes the place of the normal chute). An instance of a constructive sq. is “eat earlier than taking medication” – the fitting factor to do for somebody who’s contaminated and sends the participant up a ladder to maneuver forward within the recreation.
They trademarked their title.
One other sq. with detrimental penalties says “Blood in Urine” however the neighboring sq. gives the participant a path to redemption: “go to the well being heart” with a drawing of a smiling well being employee.
“Youngsters go up the ladder once they encounter a very good conduct [in the game] that may stop schistosomiasis,” Cynthia Umunnakwe says. These embrace “Take praziquantel in school” and “Slicing vegetation round a river” – eradicating invasive crops that supply superb situations for proliferation of the intermediate snail hosts, which carry the parasite.
The sport additionally highlights key steps of transmission.
The “Fetching water from a stream” sq. confirmed a baby stooped on the river’s edge. A schistosome worm stretched from this sq. down the board to the complication of the sickness, depicted in one other sq. studying “Swollen stomach”; whereas “Defecating close to a river,” brings the participant’s piece far down the board, touchdown on a sq. studying “Spreading an infection.” These characterize two probabilities to interrupt the parasite’s life cycle: Avoiding an infection of people on the larval stage by way of water contact and discouraging propagation of the parasite into river water by way of human waste, the place eggs in waste can then reinfect snails.
Taking part in the sport
On a go to to a schoolhouse in Apojola village in July 2025, Cynthia Umunnakwe taught younger youngsters to play “Schisto & Ladders” — a part of a Ministry of Well being program that additionally offered urine testing and therapy for these affected.
And it isn’t only a recreation. On this a part of Ogun State, a 3rd of residents screened at a urine testing clinic have been discovered to have energetic schistosomiasis an infection. The illness is widespread in these rural fishing villages the place residents depend on freshwater for every day dwelling. Tthe Oyan River is used for the important every day duties of washing garments, fishing and cleansing and getting ready cassava root, the primary crop. The shallow river’s edge can also be a playground for schoolchildren, who splash round for enjoyable — and likewise are advised by their dad and mom to test fish traps.
“Hello everybody, I’m Dr. Cynthia from Nigeria.” she says with a smile – she holds a Ph.D in parasitology – and gives a wave. She supervises the pushing of tables and benches into clusters within the classroom, after which the sport begins.
Umunnakwe additionally introduced in stay snails — acquainted to the kids who play within the river — so they may acknowledge the host for the parasite that infects people, resulting in this sickness. They have been collected by her colleague, Dr. Olubukola Adelakun. a veterinary public well being researcher and post-doctoral scholar at Federal College of Agriculture in Abeokuta who researches the habitat of those snails. She had waded waist-deep within the river water the day earlier than, clad in waterproof waders to guard from an infection. She had scrubbed their shells clear for straightforward identification, as there are lots of related freshwater snails within the space, although none of them had the attribute shell shapes of the parasite-carrying snails.
The day’s actions included medical assist as effectively. In a neighboring schoolhouse, Ministry of Well being employees provided all youngsters the oral drug praziquantel, which may each stop and deal with the illness. They obtained free snacks for collaborating, since consuming earlier than therapy will help ease abdomen ache that always happens if the drug is taken on an empty abdomen.
The workforce’s physician administered therapy doses in accordance with top, with a standardized measuring tape towards the wall to assist decide the dose.
In earlier years, Cynthia Umunnakwe had performed analysis demonstrating the sport’s affect, printed in Worldwide Well being. In a six-month research involving 275 college students throughout six faculties in rural Ogun State — faculties the place praziquantel had beforehand been rejected due to false rumors that it induced fainting and even loss of life — not a single youngster within the research group had heard of the drug earlier than enjoying the sport. The sport was performed in every college at some point of the trial, and the workforce surveyed youngsters earlier than and after the trial, performed focus group discussions with college students, dad and mom, and caregivers. By the top of the trial, greater than two-thirds of the scholars knew what the drug was and understood it was protected, and 65% put their names down, with parental permission, to obtain therapy.
“So we hope that by enjoying this recreation that the schoolchildren will truly translate the information acquired into altering their behaviors,” Umunnakwe stated,
And never solely that, the youngsters have enjoyable.
“Hey, wò ó, mo wà lókè!” stated a boy who received the sport by reaching the ultimate “Schisto-free youngster” sq.: “Hey look, I am on high!”
