5. You are a government official in a middle-income country. A crisis exists in your country because an epidemic of cholera has broken out and is spreading rapidly. You are holding an emergency meeting with other officials to decide what to do. As you plan your course of action, consider the following:

Cholera is spread by fecal contamination of food and water.
Victims become extremely thirsty and need lots of water or they will die from dehydration.
Hospitals are overcrowded in your country even when there is no epidemic.
Households can boil their drinking water for 10 minutes to make it safe. But most people are not aware of this, and, even if they were, it would cost the average poor family a third of its income to do so.
Tourism has disappeared, and other countries will no longer buy fruits and vegetables grown in your country.
