Rarest Diseases

Smallpox



We’ve all heard about smallpox, probably more so about the vaccine itself, which today is rarely used unless there is a high-risk of the disease. It is said that smallpox may have been around in as early as 10,000BC. Smallpox is characterized by a high fever, fatigue, and a rash with flat red sores that can eventually cover the entire body. Many believe that smallpox was one of the deadliest diseases, killing around 300-500 million in the 20th century, in 400,000 each year throughout the 18th century. However, due to immunization worldwide, the last reported case of smallpox was in 1977. Because of this, the disease is said to be extremely rare. Today, the threat of smallpox still exists, but in the form of bioterrorism.

Morgellons



Today, Morgellons stands as a very poorly understood disease that some doctors seem to believe if a chronic infectious disease. Sadly, the disease is usually disfiguring as well as disabling. The disease is classified by biting, itching, or crawling sensations, filaments that grow from the skin, and skin lesions, as well as memory loss, joint paint, and fatigue. Morgellons is still not recognized by the entire medical community, but there have been about 2,000 people within the U.S. who believe they suffer from the disease. Some of the reports are children, who are said to be unable to do normal things such as going to school or playing sports. There is no known cure or effective treatment for Morgellons.

Fields’ disease



Fields’ disease is said to be the rarest disease in the world. It is named after two twins, Catherine and Kirstie Fields from Wales. The disease doesn’t have a medical name, but doctors have been able to call it a neuromuscular disease. The muscles within the body slowly deteriorate, which limits movements. The girls’ disease has been studied by doctors from all over. Because the disease is so rare and unknown, doctors aren’t sure what will happen next. The disease has since limited the lives of the girls, binding them to wheelchairs and making a simple task such as writing, hard.

Fibrodysplasia ossificans progressiva (FOP)



Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disease that affects the connective tissue. The disease is said to only affect 1 in 2 million people. Around the world there have been 700 confirmed cases of the disease, 285 of those being in the U.S. FOP is classified when the body causes fibrous tissue, such as ligament, muscle, and tendons, to become ossified, or to change into bone when damaged. This means that a fall can cause bone to grow within the muscles and tendons throughout the body. FOP stands as the only disease known that causes one type of organ system to turn into an entirely different one. At birth, the classic symptom of the disease is a malformation of the big toe. There is no known treatment for FOP, as surgery to get rid of the bone, seems to cause the body to produce even more.

KURU



As rare as it is, Kuru is one disease that is fatal. However, it is so rare that the disease is confined to an area in New Guinea, more specifically the Fore tribe that lives in the highlands. The disease came about as a result of cannibalism, which is a ritualistic practice in which the tissues of others, especially the brain, were cooked and consumed. Those affected with the disease usually become unable to eat or stand, and then about 6-12 months later die in a comatose state. It is said that about 1,100 people died from Kuru during the 1950s and 60s. Because of government intervention and a wide-spread effort to end cannibalism, Kuru has now mostly disappeared.

Weird Diseases

Cotard’s Syndrome

Cotard’s Syndrome is a delusion most often present in depressed or suicidal individuals in which they believe that they are dead, do not exist, are putrefying, or have lost their blood and/or internal organs.





Progeria

Progeria is a fatal genetic disorder that is characterized by the appearance of rapid aging in children. They usually appear normal at birth, but soon show signs of rapid aging. Sadly, children suffering from Progeria usually die of heart disease early in adolescence.





Latah

“Latah” is both the name of the condition and a name for people afflicted with this condition. Latahs respond to being surprised by falling into a trance state in which they mimic the speech and actions of those around them and obey all commands given to them without thought. During these episodes, they are completely unaware of their actions.





Capgras Delusion

The Capgras delusion (or Capgras syndrome) is a rare disorder in which a person holds a delusion that an acquaintance (typically someone close) has been replaced with an imposter. This delusion can be so strong that they may actually attack the loved one.


Moebius Syndrome

Moebius Syndrome is a neurological disorder in which patients cannot use their facial muscles. They cannot blink, smile, frown, or more their eyes from side to side. Even drinking, eating, and breathing can be problematic.
