Examples of sporadic illnesses

Among the many types of existing diseases, sporadic diseases are those that occur in isolation and lack epidemic or endemic properties.

Examples of sporadic illnesses
  • Hepatitis A . It is a viral disease that affects the liver in mild or severe dimensions. The way in which this virus is transmitted is orally when a person ingests drinks or foods that contain the contaminating agent. This virus can be epidemic in developing countries or regions that do not have a high quality of standardized hygiene. However, once a person survives the ingestion of the virus, they will develop a lifelong immunology against it. The general symptoms of a person infected with hepatitis A include: fever, general malaise, loss of appetite, diarrhea, nausea, discomfort in the abdominal area, jaundice, among others.
  • Hepatitis E . Like its type A counterpart, hepatitis E is also a viral disease that directly affects the liver. The way of contracting hepatitis E is identical to that of type A, that is, orally, through the ingestion of food or liquids with the contaminating agent inside them. This virus is also common in countries or regions with limited resources , poor access to clean water, mediocre health institutions, and poor hygiene standards. The symptoms of hepatitis E are very similar to those of hepatitis A. These may include: fever, loss of appetite, nausea, the urge to vomit, abdominal pain, skin irritations and rashes, joint pain, among others.
  • Appendicitis . It is the chronic or acute inflammation of the appendix. By not being diagnosed or treated in time, the appendix can burst, consequently creating an infection. Anyone can get this disease, but it is most common in males between the ages of 10 and 30. The determining causes as to why a person is prone to contracting this disease are diverse and doctors have not reached accurate conclusions yet. Most of the medical community believe that the accumulation of substances and the obstructions created in the appendix are the main causes of this. However, other factors such as enlarged lymphoid follicles, the introduction of gastric worms into the digestive system, or the development of inflammations or tumors near the appendix can influence appendicitis.
  • Creutzfeldt-Jakob disease . It is a rare, degenerative and fatal brain disorder. The sporadic variant of this disease (abbreviated sCJD) is mainly due to the fact that the infectious prions, which are the agents responsible for causing it, are consequences of errors in the cellular machinery that manufacture the proteins necessary for the normal functioning of a person, altering and degenerating their qualities. Symptoms that present as sCJD develops include spontaneous memory loss, problems with motor coordination of certain muscles, impaired memory, judgment, impaired thinking, prolonged insomnia, trouble seeing, depression, among others.
  • Deadly insomnia . The origin of this is a result of failures in the production of cellular proteins , and like CJD, it is an atypical brain disorder. The main symptom of this disease is the lack or lack of sleep, however, others may appear such as the emergence of difficulties when trying to communicate, failures in physical coordination, depression, and dementia.
  • Alzheimer’s . It is a brain disorder that is directly related to dementia, and it is the most common manifestation of which is making up between 60 and 80 percent of cases linked to dementia. Alzheimer’s is progressively more enunciated with the passage of time and although there is no definitive cure today for this type of dementia, there are medical treatments that slow down the symptoms of this disease. Among the most common symptoms of this disease are the difficulty to retain new information, disorientation, drastic changes in mood or personality, confusion, and with the passage of time and the worsening of a person with Alzheimer’s, they may suffer the loss of total memory, difficulties moving, eating, and speaking.
  • Heart infarcts . These occur when a muscle segment or part of the heart tissue is fatally damaged by sudden blood loss.
    They happen specifically when the arteries that pump blood to the heart become blocked by blood clots. A person in the initial stages of a heart attack immediately feels severe pain in the chest, followed by unstable shocks around the heart. However, the symptoms of a heart attack are easy to detect and if the person reacts in time and intelligently, they would not run much risk. The most prominent symptom is a feeling of pressure that starts from the chest and then runs through all the extremities of the human body. The following behaviors could give more suggestions that a person would be having a heart attack, such as: coughing a lot, feeling nauseous, vomiting, suffering from respiratory disturbances, feeling exhausted,
