An endemic disease is best described as a disease in a particular community that is always present no matter what. For example, there could be a Ebola virus in a community, and they could have had that problem for a long time, and the disease will never go away, but it would be a endemic disease because the virus is only in a community and will always be in that community. Places in Africa have this problem because some villages or tribes have diseases that they can't get rid of, and people in that community start to get sick and possibly die from it The thing that people get endemic mixed up with a pandemic, and a pandemic disease is slightly different than an endemic disease. Pandemic disease meaning a worldwide spread of an disease, for example, like the Ebola virus that got spreader into different countries a few years back.
