Chapare Virus, a Newly Discovered Arenavirus Isolated from a Fatal Hemorrhagic Fever Case in Bolivia

A small focus of hemorrhagic fever (HF) cases occurred near Cochabamba, Bolivia, in December 2003 and January 2004. Specimens were available from only one fatal case, which had a clinical course that included fever, headache, arthralgia, myalgia, and vomiting with subsequent deterioration and multiple hemorrhagic signs. A non-cytopathic virus was isolated from two of the patient serum samples, ...

Re-emergence of Bolivian hemorrhagic fever.

In July and August 1994, an outbreak of Bolivian hemorrhagic fever (BHF) occurred among an extended family living in the city of Magdalena (1994 population estimates 5,300), Itenez Province, Department of Beni, Bolivia (see map). BHF, caused by the Machupo arenavilus, is known to be endemic only in Bolivia. The principal reservoir of the Machupo virus is the small rodent Calomys callosus. This ...

Emergence of a New Genotype of Crimean-Congo Hemorrhagic Fever Virus in Iran

Background and Aims: Crimean-Congo hemorrhagic fever (CCHF) is a fatal viral disease that occurs in approximately 30 countries. It has the most extensive geographic range among the tick-borne viruses that affect human health. CCHF viruses have a tripartite RNA genome consisting of large (L), medium (M) and small (S) segments. This study was undertaken to determine the genetic relationship of CC...

Re-Emergence of Crimean-Congo Hemorrhagic Fever Virus in Central Africa

BACKGROUND Crimean-Congo hemorrhagic fever (CCHF) is a severe tick-borne disease well recognized through Europe and Asia where diagnostic tests and medical surveillance are available. However, it is largely neglected in Africa, especially in the tropical rainforest of Central Africa where only sporadic human cases have been reported and date back to more than 30 years. We describe here an isola...
