For the children in Amina's village, the river was a perfect place to play. They didn't know that every swim carried a hidden risk of getting a serious illness.
After a few weeks, Amina began to feel very weak. She had a parasitic infection from the water. This sickness affects many children in her community, making it hard for them to play or go to school.
Her mother heard about special health campaigns and took Amina to a temporary clinic. The doctor gave her medicine and explained that tiny worms in the water, too small to see, cause the infection.
The health workers in the campaigns do more than just give medicine. They also teach families about the dangers of the river water and try to find ways to make it safer for everyone.
