List of diseases eliminated from the United States

Apr 22,  · The truth is, we are on the brink of eradicating a string of deadly diseases that were, until recently, affecting millions of people. It has been 35 years since the World Health Organization declared that smallpox had been eradicated. If a particular disease is eliminated worldwide, it’s considered eradicated. To date, only one infectious disease that affects humans has been eradicated.* In , after decades of efforts by the World Health Organization, the World Health Assembly endorsed a statement declaring smallpox eradicated.

This is a list of diseases known or declared to have been eliminated from the United Stateseither permanently or at one time. Most of the diseases listed were eliminated after coordinated public health campaigns. Since some diseases can be eliminated and then reintroduced at a later time, such diseases are still eligible for the list, but with the fact of reintroduction noted. Some entries are based on formal public health declarations, others are based on reliable information in the medical or public health literature.

Since some diseases can be eliminated, but subsequently reimported without transmitting additional endemic cases, these are noted in a dedicated column. Although no fixed rule always applies, many infectious diseases e.

NB: In recent years, "elimination" is the preferred term for "regional eradication" of a disease; the term "eradication" is reserved for the reduction of an infectious disease's global prevalence to zero. Various public health projects are going on, with a goal of eliminating diseases from the country. Other disease pathogens e. The stated goal of "eradication" of hookworm from the southeast US was not achieved, although the hookworm-infection rate of that region did drop by more than half.

Diseases On The Verge Of Being Eradicated (Globally)

One of the deadliest diseases known to humans, smallpox is the only human disease to have been eradicated by vaccination. Thirty Years of a Smallpox-Free World. The last known case occurred in Somalia in Read more. Smallpox eradication campaign WHO photo by T. Polio, for example, was eliminated in the United States by after widespread vaccination efforts.

To date, only one infectious disease that affects humans has been eradicated. Smallpox eradication was accomplished with a combination of focused surveillance—quickly identifying new smallpox cases—and ring vaccination. The last case of wild smallpox occurred in Somalia in Smallpox was a good candidate for eradication for several reasons. First, the disease is highly visible: smallpox patients develop a rash that is easily recognized.

Workers from the World Health Organization found smallpox patients in outlying areas by displaying pictures of people with the smallpox rash and asking if anyone nearby had a similar rash.

Second, only humans can transmit and catch smallpox. Some diseases have an animal reservoir, meaning they can infect other species besides humans. Yellow fever, for example, infects humans, but can also infect monkeys. If a mosquito capable of spreading yellow fever bites an infected monkey, the mosquito can then give the disease to humans.

So even if the entire population of the planet could somehow be vaccinated against yellow fever, its eradication could not be guaranteed. The disease could still be circulating among monkeys, and it could re-emerge if human immunity ever waned. The discovery of an animal reservoir for yellow fever was in fact what derailed a yellow fever eradication effort in the early s.

Smallpox, however, can infect only humans. In effect, aside from the human population, it has nowhere to hide. Equally important is the ability to protect individuals against infection. People who survived smallpox naturally developed lifelong immunity against future infection. For everyone else, vaccination was highly effective. WHO trained vaccinators quickly, and they could immunize large groups of people in a short time.

The eradication of smallpox raised hopes that the same could be accomplished for other diseases, with many named as possibilities: polio, mumps, and dracunculiasis Guinea worm disease , among others. Malaria has also been considered, and its incidence has been reduced drastically in many countries. It presents a challenge to the traditional idea of eradication, however, in that having malaria does not result in lifelong immunity against it as smallpox and many other diseases do.

It is possible to fall ill with malaria many times, although individuals may develop partial immunity after multiple attacks. In addition, although promising steps have been made, no effective malaria vaccine yet exists. Other diseases present additional challenges. Polio, though it has been reduced or eliminated in most countries through widespread vaccination, still circulates in some areas because among other reasons many cases do not present easily recognizable symptoms.

As a result, an infected person can remain unnoticed, yet still spread the virus to others. Measles is problematic in a similar way: although the disease results in a highly visible rash, a significant period of time elapses between exposure to the virus and the development of the rash.

Patients become contagious before the rash appears, and can spread the virus before anyone realizes they have the disease. Guinea worm disease is likely on the verge of eradication. Only 30 cases were reported in , from just 2 countries Chad [15 cases], Ethiopia [15 cases]. The Carter Center International Task Force for Disease Eradication has declared six additional diseases as potentially eradicable: lymphatic filariasis Elephantiasis , polio, measles, mumps, rubella, and pork tapeworm.

At the time, smallpox was endemic in 12 countries or territories in eastern and southern Africa, 11 in western and central Africa, seven in Asia, and Brazil in the Americas. The WHO program designated two main components to its eradication plan: mass vaccinations using freeze-dried vaccine material of carefully monitored quality, and the development of a system to detect, monitor, and investigate smallpox cases and contain outbreaks. WHO efforts came under criticism from some health workers and human rights advocates.

Some public health administrators charged that campaign workers at times bent WHO and local regulations. Some human rights advocates objected to the search and quarantine aspects of the program. Later, some critics claimed that physicians used coercion to ensure vaccination of quarantined individuals. Which of the following is a reason that eradicating polio may be difficult?
