What is the difference between elimination and eradication




















Programs are in place to eradicate polio a highly infectious disease that causes paralysis within hours of transmission — eliminated from the United States since and only 33 reported cases in worldwide and guinea-worm disease a parasite infection spread through contaminated food or water — eliminated in most parts of the world except parts of Africa. It is critical to understand the difference between elimination and eradication, as measles is still present in many parts of the world.

In , the World Health Organization reported 7 million cases of measles worldwide and 89, deaths. Unvaccinated individuals, including children under the age of 5, should avoid going to areas of the world where outbreaks are ongoing. All travelers should check with their doctor that they are up to date on all recommended vaccines before international travel. Skip to primary navigation Skip to main content Skip to footer.

Case count is preliminary and subject to change. During the past year, several countries, including Cuba, Thailand, and a handful of others have received official validation from the World Health Organization WHO that they have eliminated mother-to-child transmission of HIV—a key step to ending the entire AIDS epidemic. However, the challenge with diseases such as HIV and polio is that ending these diseases also depends on populations getting a vaccine, adhering to medication regimens, and other behavioral changes.

Disease eradication is the permanent reduction of a disease to zero cases through deliberate measures such as vaccines. Once a disease has been eradicated, intervention measures are no longer needed. As the Carter Center recently announced, cases of Guinea worm disease have fallen from more than 3 million cases annually in the s, to a total of only two confirmed cases so far in Guinea worm disease is a parasitic infection that is contracted through contact with contaminated water. It has no cure, but thanks to water and sanitation efforts in endemic countries, the parasite itself is almost extinct, which means that we might see the very last Guinea worm infection in the near future.

If a country wants to get the official elimination status by the WHO, it must request through a formal submission process. The WHO will grant certification of elimination only if a country proves that their interruption of disease transmission has lasted for three consecutive years, at a minimum.

Disease eradication refers to the permeant reduction of a disease to zero cases through deliberate preventative actions such as vaccines. Eradication is not limited to a specific geographic location.

It refers to the worldwide eradication of a disease. When we eradicate a disease, its worldwide transmission is over as there are no remaining cases. Therefore, further intervention measures are unnecessary.

Smallpox is the only disease considered to be completely eradicated from the world. It was officially declared eradicated by the WHO in
