Alkhurma hemorrhagic fever virus (genus Flavivirus, AHFV) was recently identified as the agent of a viral hemorrhagic fever in Saudi Arabia and characterized serologically and genetically as a variant genotype of Kyasanur Forest disease virus (KFDV). Since viral diagnosis and vaccine development may be hindered by genetic diversity, this study was intended to address AHFV genetic heterogeneity....

Alkhurma virus is a flavivirus, discovered in 1994 in a person who died of hemorrhagic fever after slaughtering a sheep from the city of Alkhurma, Saudi Arabia. Since then, several cases of Alkhurma hemorrhagic fever (ALKHF), with fatality rates up to 25%, have been documented. From January 1, 2006, through April 1, 2009, active disease surveillance and serologic testing of household contacts i...

media coverage when outbreaks occur. The causative organisms are found in tropical Africa and the Philippines. They belong to the Filoviridae family. Clinical presentations of the viral infections they cause share many common characteristics. At least 6 Marburg virus outbreaks and 21 Ebola virus outbreaks have been documented to date (Table 1). More outbreaks have probably occurred in remote ar...

Dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) are life threatening clinical manifestations of infection due to dengue virus. The clinical features of DHF/DSS are due to bleeding diathesis and increased capillary leak(l). The mechanisms of hemorrhagic manifestations in DHF/DSS are not well understood. The suggested factors contributing to bleeding include thrombocytopenia, coagu...

introductio dengue fever is the world’s most important hemorrhagic fever, especially in america, pacific islands, and asia. in countries like ours where viral hepatitis, malaria, enteric fever are common; it represents a challenge to identify the etiology of acute fever complicated by hepatitis. case presentation we report a case of acute hepatitis in a 7-year-old male with dengue hemorrhagic f...

Three cases of Rift Valley fever in human individuals are reported. The virus was recovered from the respiratory tract of the patients and was transmitted to ferrets by the intranasal route. The experimental disease so produced in ferrets is characterized by fever, marked pulmonary lesions, and hemorrhagic phenomena. The results indicate that the virus of Rift Valley fever belongs to the group ...

Despite its isolation three decades ago, Ebola virus continues to cause periodic outbreaks of severe hemorrhagic fever in humans, and the closely related Marburg virus is responsible for a recent outbreak of disease in Angola. The mortality rate associated with Ebola virus infection can reach 90 percent, and so the prospect of an effective therapy is attractive. A recent study by Chandran et al. 1

BACKGROUND Hemorrhagic fever with renal syndrome (HFRS) is a rodent-borne disease caused by Hantaviruses. It is endemic in all 31 provinces, autonomous regions, and metropolitan areas in mainland China where human cases account for 90% of the total global cases. Shandong Province is among the most serious endemic areas. HFRS cases in Shandong Province were first reported in Yutai County in 1968...
