Information: - Vuosaari is a neighbourhood in the City of Helsinki, Finland. It is located by the sea in East Helsinki and with its area of 15.38km is geographically the largest district in the city. It also has two Helsinki Metro stations, Rastila and Vuosaari - Lasse Lind ( born 1 March 1981 ) is a Finnish football midfielder who currently plays for FC Viikingit . - FC Viikingit is a Finnish football club based in Vuosaari, East Helsinki, and currently playing in the "Kakkonen", the second tier of Finnish football. They play their home matches at Vuosaaren urheilukentta, also called Heteniitty. The club's name and crest refer to Vikings, and they are known for their red colour. - East Helsinki is an area in Helsinki, Finland, usually thought to comprise the city's eastern and south-eastern major districts ("suurpiiri" in Finnish, "stordistrikt" in Swedish), including the districts of Vartiokyla, Myllypuro, Mellunkyla, Vuosaari, Herttoniemi, Laajasalo and Kulosaari. With the exception of Kulosaari, the buildings in the area are relatively new (most have been built in the 1960s or later) and constitute relatively densely inhabited suburbs (except the southern part of Laajasalo and most of Kulosaari). - Vikings (Danish and ; Swedish and ), from Old Norse "", were Nordic seafarers, mainly speaking the Old Norse language, who raided and traded from their Northern European homelands across wide areas of northern, central and eastern Europe, during the late 8th to late 11th centuries. The term is also commonly extended in modern English and other vernaculars to the inhabitants of Viking home communities during what has become known as the Viking Age. This period of Nordic military, mercantile and demographic expansion constitutes an important element in the early medieval history of Scandinavia, Estonia, the British Isles, France, Kievan Rus' and Sicily.

Question: Information: - The BK virus is a member of the polyomavirus family. Past infection with the BK virus is widespread, but significant consequences of infection are uncommon, with the exception of the immunocompromised and the immunosuppressed. - The JC virus or John Cunningham virus (JCV, not to be confused with Jamestown Canyon virus that bears the same initials) is a type of human polyomavirus (formerly known as papovavirus) and is genetically similar to BK virus and SV40. It was identified by electron microscopy in 1965 by ZuRhein and Chou, and by Silverman and Rubinstein, and later isolated in culture and named using the two initials of a patient, John Cunningham, with progressive multifocal leukoencephalopathy (PML). The virus causes PML and other diseases only in cases of immunodeficiency, as in AIDS or during treatment with drugs intended to induce a state of immunosuppression (e.g. organ transplant patients). - SV40 is an abbreviation for Simian vacuolating virus 40 or Simian virus 40, a polyomavirus that is found in both monkeys and humans. It was named for the effect it produced on infected green monkey cells, which developed an unusual number of vacuoles. Like other polyomaviruses, SV40 is a DNA virus that has the potential to cause tumors in animals, but most often persists as a latent infection. - Progressive multifocal leukoencephalopathy ( PML ) is a rare and usually fatal viral disease characterized by progressive damage ( - pathy ) or inflammation of the white matter ( leuko - ) of the brain ( - encephalo - ) at multiple locations ( multifocal ) . It is caused by the JC virus , which is normally present and kept under control by the immune system . JC virus is harmless except in cases of weakened immune systems . In general , PML has a mortality rate of 30 -- 50 percent in the first few months and those who survive can be left with varying degrees of neurological disabilities . PML occurs almost exclusively in patients with severe immune deficiency , most commonly among patients with acquired immune deficiency syndrome ( AIDS ) , but people on chronic immunosuppressive medications including chemotherapy are also at increased risk of PML , such as patients with transplants , Hodgkin 's Lymphoma , multiple sclerosis , psoriasis and other autoimmune diseases . - 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.
