Chieh-Cheng Lin, Wen-Ching Chen
BACKGROUND About 400 million cases of dengue, a mosquito-borne disease, are reported annually, but no drug is yet available for treatment. In 1988, at Feng Lin Clinic, Taiwan, we encountered about 10,000 cases and tested various drugs before confirming an antiviral effect of amantadine against dengue virus in vitro. After we administered amantadine to patients for 1-2 days, most achieved full remission. None experienced potentially life-threatening dengue hemorrhagic fever or dengue shock syndrome. Herein, we present 34 cases from recent clinical experience that show amantadine's unusual effect against dengue virus infection...

Hantaan virus (HTNV), identified in the striped field mouse (Apodemus agrarius), belongs to the hantavirus genus of the Bunyaviridae family and contains tripartite RNA genomes, small (S), medium (M), and large (L) segments. HTNV is a major causative for hemorrhagic fever with renal syndrome (HFRS) with fatality rates ranging from 1% to 15% in the Republic of Korea (ROK) and China. Defining of HTNV whole-genome sequences and isolation of the infectious particle play a critical role in the characterization and preventive and therapeutic strategies of hantavirus outbreaks...

BACKGROUND Leptospirosis is a zoonosis transmitted through urine of infected animals. Symptoms range from mild influenza-like symptoms to severe pulmonary hemorrhagic syndrome (SPHS); the latter are often fatal. The serogroup distribution in Denmark has changed from 1988 to 2012, with Icterohaemorrhagiae and Sejroe now being predominant. CASE REPORT A 45-year-old Danish woman living in an area endemic for Hanta virus, without prior medical history, was admitted because of lower back pain radiating to the left hip, fever, headache, nausea, and malaise...

BACKGROUND: Ebola virus (EBOV) is a Category A pathogen that is a member of Filoviridae family that causes hemorrhagic fever in humans and non-human primates. Unpredictable and devastating outbreaks of disease have recently occurred in Africa and current immunoprophylaxis and therapies are limited. The main limitation of working with pathogens like EBOV is the need for costly containment. To potentiate further and wider opportunity for EBOV prophylactics and therapies development, innovative approaches are necessary...

Crimean Congo hemorrhagic fever virus (CCHFV) is one of the most severe viral zoonozes. It is prevalent throughout Africa, Asia and southern Europe. Limited availability of sequence data has hindered phylogeographic studies. The complete genomic sequence of all three segments of 14 Crimean Congo hemorrhagic fever virus strains isolated from 1958-2000 in Russia, Central Asia and Africa was identified. Each genomic segment was independently subjected to continuous Bayesian phylogeographic analysis. The origin of each genomic segment was traced to Africa about 1,000-5,000 years ago...

Crimean-Congo hemorrhagic fever (CCHF) is a viral zoonotic disease which is endemic in Iran. The etiological agent of CCHF is an RNA virus belonging to the genus Nairovirus of the family Bunyaviridae. CCHF virus (CCHFV) can be transmitted to humans through bites from infected ticks and direct contact with infected blood or tissues. Although the disease has been observed in different age groups, the rate of disease is lower in children and elderly. This study was designed to characterize CCHFV-infected children in Iran...

Ebola virus (EBOV) is an enveloped, ssRNA virus from the family Filoviridae capable of causing severe hemorrhagic fever with up to 80-90% mortality rates. The most recent outbreak of EBOV in West Africa starting in 2014 resulted in over 11,300 deaths; however, long-lasting persistence and recurrence in survivors has been documented, potentially leading to further transmission of the virus. We have previously shown that exosomes from cells infected with HIV-1, HTLV-1 and Rift Valley Fever virus are able to transfer viral proteins and non-coding RNAs to naïve recipient cells, resulting in an altered cellular activity...

Dengue fever and dengue hemorrhagic fever are globally important mosquito-transmitted viral diseases. However, the only licensed vaccine is not highly protective. Viremia is related to disease severity in infected humans, and it is thought to be reduced by neutralizing antibodies but increased by infection-enhancing antibodies. We established an assay system to measure the balance between neutralizing and enhancing antibodies and found that most dengue-immune individuals in endemic areas carry complement-independent enhancing antibodies (CiEAb)...

Several arenaviruses, chiefly Lassa (LASV) in West Africa, cause hemorrhagic fever (HF) disease in humans and pose important public health problems in their endemic regions. To date, there are no FDA-approved arenavirus vaccines and current anti-arenaviral therapy is limited to the use of ribavirin that has very limited efficacy. In this work we document that a recombinant prototypic arenavirus lymphocytic choriomeningitis virus (LCMV) with a codon deoptimized (CD) surface glycoprotein (GP), rLCMV/CD, exhibited wild type (WT)-like growth properties in cultured cells despite barely detectable GP expression levels in rLCMV/CD-infected cells...

Ebolaviruses are highly dangerous pathogens exhibiting extreme virulence in humans and nonhuman primates. The majority of ebolavirus species, most notably Zaire ebolavirus, can cause Ebola virus disease (EVD), formerly known as Ebola hemorrhagic fever, in humans. EVD is associated with case-fatality rates as high as 90%, and there is currently no specific treatment or licensed vaccine available against EVD. Understanding the molecular biology and pathogenesis of ebolaviruses is important for the development of antiviral therapeutics...

Dengue virus (DENV) is a mosquito-borne virus belonging to the Flaviviridae family. There are 4 serotypes of DENV that cause human disease through transmission by mosquito vectors. DENV infection results in a broad spectrum of clinical symptoms, ranging from mild fever to dengue hemorrhagic fever (DHF), the latter of which can progress to dengue shock syndrome (DSS) and death. Researchers have made unremitting efforts over the last half-century to understand DHF pathogenesis. DHF is probably caused by multiple factors, such as virus-specific antibodies, viral antigens and host immune responses...

BACKGROUND: Hantavirus disease belongs to the emerging infections. The clinical picture and severity of infections differ between hantavirus species and may even vary between hantavirus genotypes. The mechanisms that lead to the broad variance of severity in infected patients are not completely understood. Host- and virus-specific factors are considered. CASE PRESENTATION: We analyzed severe cases of hantavirus disease in two young women. The first case was caused by Puumala virus (PUUV) infection in Germany; the second case describes the infection with Dobrava-Belgrade virus (DOBV) in Russia...

Viral hemorrhagic fevers with their high mortality rates, lack of medical countermeasures, and potential use as instruments of bioterrorism, pose a significant threat to the developed and the developing areas of the world. The key to preventing the spread of these diseases is early and accurate detection. For decades, the gold-standard immunoassay for hemorrhagic fever detection has been the ELISA; however newer technologies are emerging with increased sensitivity. One such technology is the Luminex MAGPIX®™ platform using XMAP® microspheres...
