The grass huts that the people live in contribute to widespread disease. These huts are filled with dangerous mold. Also bats nest in the rafters and their feces and urine drop on the people living in the huts creating open sores and causing all sorts of health problems. The water they drink is filled with parasites and most of the people are filled with worms. These worms eat what little nutrition the people ingest causing them to slowly die of malnutrition.
Juan’s first priority in helping a new village is to bring a team of doctors who administer basic medicines to cure the immediate and obvious diseases. They bring antibiotics and medicines that treat worms.
