Laughter sounds pretty awkward Just awful number three is nodding disease first discovery in Tanzania in the 1960s This bizarre disease causes those afflicted with it to nod their head uncontrollably It also stuns growth making those affected with it appear much younger than they really are It originally was never given much attention by doctors. However in recent years It's made a big reemergence despite the reportedly large number of cases in countries like Sudan and Uganda Doctors remain clueless as to exactly what this is They believe that it could be an illness caused by a parasite But that's really just a guess the worst part about it Is that the nodding is triggered by simple everyday events like eating causing its victims to be malnourished Which makes a lot of sense if you think about it kind of makes it hard to eat soup when you're a living bobblehead You know what I'm saying number four is sweating sickness sweating sickness is a particularly frightening disease because not only does nobody know what causes it But death occurs within only a matter of hours of first seen symptoms the disease occurs in two specific stages The first stage is the cold stage accompanied by violent shivers headache pain in the limbs and giving laughter The second stage is the hot stage which is accompanied by delirium rapid pulse intense thirst and of course buckets in buckets of sweat There have been six different outbreaks of this disease in the past that have killed so many people so quickly that there was no time to Diagnose why it happens I think it's interesting that almost all of the symptoms of this disease are identical to that of the common flu So basically you wouldn't know you had sweating sickness until you well died Oh, of course unless you're a grown man and you start feeling like a little schoolgirl that should tip you off Number five is the Marburg virus the Marburg virus is one of the nastier diseases on this list It's clinical symptoms are indistinguishable from that of the Ebola virus and include disruption of the central nervous system Tissue necrosis and seizures among several others that are equally disturbing the scariest thing about this disease is that not only does nobody know how it's transmitted But it's not confined to any one part of the world In fact the most recent cases occurred in the Netherlands in Colorado It's believed that the infection could be contracted through direct contact with an animal host such as monkeys and bats So basically just don't go play with monkeys and bats and you should be fine Although common sense folks it goes a long way number six is sleeping sickness also known as encephalitis lethargica This illness causes those affected to be unable to move despite being fully conscious giving them a strange half-asleep appearance It begins innocently enough with a sore throat But ends in hallucinations insanity in an emotional state those who are lucky enough to survive this disease live the rest of their lives as Unresponsive vegetables who sometimes break out in violent fits either the origin of the sickness or what causes it are known But it's believed to most likely be a virus of some kind number seven is stick-person syndrome SPS or stick-person syndrome is a Disease that causes the body of a person affected to become progressively We keep this time goes on their muscles become increasingly constricted until eventually their body becomes so rigid that they're paralyzed Unfortunately, it doesn't end there as it has other effects as well including problem swallowing
