Endemic means a disease that occurs in a certain place or group of people. For example, the common cold occurs predictably among American schoolchildren.

A sizable outbreak can overwhelm the health system, limiting the capacity to deal with routine health issues and compounding the problem. Travel and tourism to regions affected by outbreaks are also likely to decline. Some long-running epidemics, such as HIV and malaria, deter foreign direct investment as well.

Examples of endemic diseases include chicken pox that occurs at a predictable rate among young school children in the United States and malaria in some areas of Africa. The disease is present in a community at all times but in relatively low frequency.

Endemic. a disease that exists in a certain region or population. Epidemic. a widespread occurrence of a disease that attacks many peoples at the same time and can spread through one or multiple communities.

What is the difference between an epidemic and a pandemic? An epidemic occurs when the communicable disease spreads from person to person and affects a large number of people. A pandemic occurs over a wide geographic area and affects a high proportion of the population.

An epidemic is the occurrence of disease in excess of normal in a specific community or region, usually occurring suddenly and spreading rapidly. It is often referred to as an “outbreak” of disease. An example of an epidemic would be an influenza outbreak. You just studied 2 terms!

An endemic disease is a disease that is always present in a certain population or region. One of the most talked-about endemic diseases is malaria. The CDC estimates that around half the world’s population live in areas where they are at risk of Malaria infection.

What is an Epidemic? The CDC (Centers for Disease Control and Prevention) describes an epidemic as an unexpected increase in the number of disease cases in a specific geographical area. Yellow fever, smallpox, measles, and polio are prime examples of epidemics that occurred throughout American history.

Epidemic refers to an increase, often sudden, in the number of cases of a disease above what is normally expected in that population in that area. Outbreak carries the same definition of epidemic, but is often used for a more limited geographic area.

An epidemic (from Greek ἐπί epi “upon or above” and δῆμος demos “people”) is the rapid spread of disease to a large number of people in a given population within a short period of time.

Harris believes that the rapid spread of Spanish flu in the fall of 1918 was at least partially to blame on public health officials unwilling to impose quarantines during wartime.

Newspapers were free to report the epidemic’s effects in neutral Spain, such as the grave illness of King Alfonso XIII, and these stories created a false impression of Spain as especially hard hit. This gave rise to the name “Spanish” flu.

Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919. In the United States, it was first identified in military personnel in spring 1918. It is estimated that about 500 million people or one-third of the world’s population became infected with this virus.

7 Deadliest Diseases in History: Where are they now?

• The Black Death: Bubonic Plague.
• The Speckled Monster: Smallpox.
• Severe Acute Respiratory Syndrome (SARS)
• Avian Influenza: Not Just One For The Birds.
• Ebola: On The Radar Again.
• Leprosy: A Feared Disease That Features In The Old Testament.
• Polio: The Most Dreaded Childhood Disease Of The 1940-50s.

Much of the high death rate can be attributed to crowding in military camps and urban environments, as well as poor nutrition and sanitation, which suffered during wartime. It’s now thought that many of the deaths were due to the development of bacterial pneumonias in lungs weakened by influenza.
