The same colors are used in the graph in the middle which shows how many people are healthy, bitten, and sick as the model runs for five virtual years. Each column represents one month. We added wetlands and rice paddies or fish ponds that show up as blue patches. They change from dark blue to light blue as the seasons change from wet to dry. In one model, they disappear when they get treated.
Green spots show up in the rainy season.
Watch how the disease lingers in these spots.
