This is a mysterious and horrible disease, which has suddenly reappeared recently. Patients will feel that there are insects crawling under the skin tissue, and what is even more frightening is that colored fibers will grow out of the wound, which is unbearable. Many medical workers think that Mojilong's disease is an illusion, and those fibers may be attached to the skin from the outside, but some people think that this disease does exist. 2. Chronic fatigue syndrome Chronic fatigue syndrome is a typical disease symptom that cannot be explained in medicine. At present, diagnosis can only be made by "excluding other diseases". The patient didn't feel a little tired. On the contrary, they often lie in bed for a few days and can't move at all. 3. Another version of this rare brain dysfunction disease CJD is what we are familiar with at present. Mad cow disease can spread across species. If you eat beef with mad cow disease by mistake, it will lead to human infection with mad cow disease.

Although it has been confirmed that this disease is related to the lack of certain minerals in the human body, health experts still have not found the real cause of pica, and there is no effective treatment for this "preference disorder" in the medical field at present. 7. Avian Influenza At present, human beings are not immune to this powerful virus carried by birds. Recently, officials claimed that they were worried that the bird flu virus might mutate and lead to human-to-human infection. However, all the cases found so far are caused by direct contact with sick birds. The mortality rate of avian influenza virus infection is about 50%, and the recent high incidence of avian influenza seems to indicate the trend of large-scale spread of the disease among people. 8. catching a cold is a systemic disease with respiratory tract mucosal infection as the main symptom. It is relatively common at present. Sudden weather changes and careless warmth may cause colds.

It is a hereditary brain dysfunction disease, and the incidence of each patient is very different. They will gradually forget everything they know around them because of brain atrophy until the end of their lives. At present, the development of the pathogen source and treatment of this disease is limited. 10.
