Bolivian hemorrhagic fever

Bolivian hemorrhagic fever (BHF), also known as black typhus or Ordog Fever, is a <a href="/facts/Hemorrhagic_fever/TARXxnRD">hemorrhagic fever</a> and <a href="/facts/Zoonosis/uvEPgxJ4">zoonotic</a> <a href="/facts/Infectious_disease/182XrncP">infectious disease</a> originating in <a href="/facts/Bolivia/YNBoDKKR">Bolivia</a> after infection by Machupo virus.
BHF was first identified in 1963 as an ambisense <a href="/facts/RNA_virus/qwXPeATD">RNA virus</a> of the <a href="/facts/Arenaviridae/qXzpWgKn">Arenaviridae</a> family, by a research group led by <a href="/facts/Karl_Johnson_(virologist)/AII2Ulfl">Karl Johnson</a>. The mortality rate is estimated at 5 to 30 percent. Due to its <a href="/facts/Pathogenicity/axMXtV1M">pathogenicity</a>, Machupo virus requires <a href="/facts/Biosafety_Level/Akgr5nIf">Biosafety Level</a> Four conditions, the highest level.
During the period between February and March 2007, some 20 suspected BHF cases (3 fatal) were reported to the Servicio Departamental de Salud (SEDES) in <a href="/facts/Beni_Department/JWWDq2mg">Beni Department</a>, Bolivia. In February 2008, at least 200 suspected new cases (12 fatal) were reported to SEDES. In November 2011, a second case was confirmed near the departmental capital of <a href="/facts/Trinidad,_Bolivia/zQ1yEIkM">Trinidad</a>, and a serosurvey was conducted to determine the extent of Machupo virus infections in the department. A SEDES expert involved in the survey expressed his concerns about the expansion of the virus to other provinces outside the endemic regions of <a href="/facts/Mamor%C3%A9_Province/hTnYf6WU">Mamoré</a> and <a href="/facts/It%C3%A9nez_province/qlqI5n9s">Iténez provinces</a>.
