An epidemic disease is one that occurs suddenly in a region or area and affects a larger number of people than usual. In this case, the earthquake disrupted sanitation and led to the spike in cholera cases on the island, which is an example of an epidemic disease. It is not an endemic disease, which is one that is always present at a low level in a particular region. It is also not a pandemic disease, which is a worldwide outbreak of a disease that affects a large number of people in different locations. Finally, it is not an opportunistic infection, which is a type of infection that takes advantage of a weakened immune system.
