Answer the following question: Information:  - Bornholm disease or epidemic pleurodynia or epidemic myalgia is a disease caused by the Coxsackie B virus or other viruses . It is named after the Danish island of Bornholm where early cases occurred .  - A disease is a particular abnormal condition, a disorder of a structure or function, that affects part or all of an organism. The study of disease is called pathology which includes the causal study of etiology. Disease is often construed as a medical condition associated with specific symptoms and signs. It may be caused by external factors such as pathogens, or it may be caused by internal dysfunctions particularly of the immune system such as an immunodeficiency, or a hypersensitivity including allergies and autoimmunity.  - Myocarditis, also known as inflammatory cardiomyopathy, is inflammation of the heart muscle. Symptoms can include shortness of breath, chest pain, decreased ability to exercise, and an irregular heartbeat. The duration of problems can vary from hours to months. Complications may include heart failure due to dilated cardiomyopathy or cardiac arrest. Myocarditis is most often due to a viral infection. Other causes include bacterial infections, certain medications, toxins, and autoimmune disorders. A diagnosis may be supported by an electrocardiogram (ECG), increased troponin, heart MRI, and occasionally a heart biopsy. An ultrasound of the heart is important to rule out other potential causes such as heart valve problems. Treatment depends on both the severity and the cause. Medications such as ACE inhibitors, beta blockers, and diuretics are often used. A period of no exercise is typically recommended during recovery. Corticosteroids or intravenous immunoglobulin (IVIG) may be useful in certain cases. In severe cases an implantable cardiac defibrillator or heart transplant may be recommended. In 2013, about 1.5 million cases of acute myocarditis occurred. While people of all ages are affected, the young are most often affected. It is slightly more common in males than females. Most cases are mild. In 2015 cardiomyopathy, including myocarditis, resulted in 354,000 deaths up from 294,000 in 1990. The initial descriptions of the condition are from the mid-1800s.  - Pathology (from the Greek roots of "pathos", meaning "experience" or "suffering", and "-logia", "study of") is a significant component of the causal study of disease and a major field in modern medicine and diagnosis.  - Immunodeficiency (or immune deficiency) is a state in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. Most cases of immunodeficiency are acquired ("secondary") due to extrinsic factors that affect the patient's immune system. Examples of these extrinsic factors include HIV infection, extremes of age, and environmental factors, such as nutrition. In the clinical setting, the immunosuppression by some drugs, such as steroids, can be either an adverse effect or the intended purpose of the treatment. Examples of such use is in organ transplant surgery as an anti-rejection measure and in patients suffering from an overactive immune system, as in autoimmune diseases. Some people are born with intrinsic defects in their immune system, or primary immunodeficiency. A person who has an immunodeficiency of any kind is said to be immunocompromised. An immunocompromised person may be particularly vulnerable to opportunistic infections, in addition to normal infections that could affect everyone. Immunodeficiency also decreases cancer immunosurveillance, in which the immune system scans the body's cells and kills neoplastic ones.  - Coxsackie B is a group of six serotypes of Coxsackievirus, a pathogenic enterovirus, that trigger illness ranging from mild gastrointestinal distress to full-fledged pericarditis and myocarditis (Coxsackievirus-induced cardiomyopathy).   - Pericarditis is inflammation of the pericardium (the fibrous sac surrounding the heart). Symptoms typically include sudden onset of sharp chest pain. The pain may also be felt in the shoulders, neck, or back. It is typically better sitting up and worse with lying down or breathing deep. Other symptoms may include fever, weakness, palpitations, and shortness of breath. Occasionally onset of symptoms is gradual. The cause of pericarditis is believed to be most often due to a viral infection. Other causes include bacterial infections such as tuberculosis, uremic pericarditis, following a heart attack, cancer, autoimmune disorders, and chest trauma. The cause often remains unknown. Diagnosis is based on the chest pain, a pericardial rub, specific electrocardiogram (ECG) changes, and fluid around the heart. Other conditions that may produce similar symptoms include a heart attack. Treatment in most cases is with NSAIDs and possibly colchicine. Steroids may be used if those are not appropriate. Typically symptoms improve in a few days to weeks but can occasionally last months. Complications can include cardiac tamponade, myocarditis, and constrictive pericarditis. It is a less common cause of chest pain. About 3 per 10,000 people are affected per year. Those most commonly affected are males between the ages of 20 and 50. Up to 30% of those affected have more than one episode. Signs and symptoms. Substernal or left precordial pleuritic chest pain with radiation to the trapezius ridge (the bottom portion of scapula on the back), which is relieved by sitting up and bending forward and worsened by lying down (recumbent or supine position) or inspiration (taking a breath in), is the characteristic pain of pericarditis. The pain may resemble the pain of angina pectoris or heart attack, but differs in that pain changes with body position, as opposed to heart attack pain that is pressure-like, and constant with radiation to the left arm and/or the jaw. Other symptoms of pericarditis may include dry cough, fever, fatigue,...    What object entity has the relation of 'medical specialty' with the subject 'bornholm disease'?   Choices: - infection  - infectious disease  - pathology
Answer:
infectious disease
