Dengue hemorrhagic fever or DHF is an infectious disease caused by the dengue virus and characterized thrombocytopenia. Thrombocytopenia that persists in can cause life-threatening complications. Monitoring platelet count, addition to hematocrit level, important determine severity of DHF. Therapy for currently focuses on supportive symptomatic therapy. Alternative therapy using guava (Psidium g...

since 1999, many cases of crimean-congo hemorrhagic fever have been reported from different parts of iran. this study intended to define cchf seroprevalence, incidence rates, and the most important risks in sistan- baluchestan province, iran. using cluster sampling with probability proportional to size, 310 subjects were selected from various districts of zahedan and zabol in the northern part ...

background: crimean-congo hemorrhagic fever (cchf) is a disease characterized by serious course, including acute viral fever, ecchymosis, thrombocytopenia, liver dysfunction and high rate of mortality. hypoxia inducible factor-1α (hif-1α) and vascular endothelial growth factor-a (vegf-a) play an important role both in the inflamma­tory process and plasma leakage. the aim of this study was to de...

case presentation this article presents a 56-year-old woman from guilan province, the north of iran and the southern coast of the caspian sea, who admitted to the hospital with acute fever, severe headache, thrombocytopenia, anemia, epigastric pain, myalgia, nausea and vomiting. conclusions we recognized that the case was co-infected by cchf and leptospirosis. introduction infectious diseases a...

We conducted a cross-sectional serosurvey of Crimean-Congo hemorrhagic fever (CCHF) among livestock in 22 states and 1 union territory of India. A total of 5,636 samples from bovines, sheep, and goats were screened for CCHF virus IgG. IgG was detected in 354 samples, indicating that this virus is widespread in this country.

Sir: Hantaviruses (genus Hantavirus, family Bunyaviridae) are carried worldwide by rodents, bats and insectivores. In Europe, hemorrhagic fever with renal syndrome (HFRS) may be caused by infection with Dobrava virus (DOBV), carried by Apodemus flavicollis (yellow-necked mouse). A milder form of HFRS –nephropathia epidemica-may be caused by infection with Puumala virus (PUUV), carried by Myodes...

Two cases of Crimean-Congo hemorrhagic fever were reported in Spain during 2016. We obtained the virus from a patient sample and characterized its full genomic sequence. Phylogenetic analysis indicated that the virus corresponds to the African genotype III, which includes viruses previously found in West and South Africa.

Dengue virus is a single stranded enveloped RNA virus belonging to the genus flavivirus in the family Flaviviridae and transmitted through the bites of Aedes mosquitoes (Gould EA et al, 2008). There are five serotypes of the virus distinguished on the basis of antigenicity; first four are referred to as DENV-1, DENV-2, DENV-3 and DENV-4 (Rodenhuis Zybert et al, 2010) while the fifth type was an...

The case of a child with Crimean-Congo hemorrhagic fever (CCHF) presumably infected with CCHF virus from her 27-year-old mother is described. The mother with CCHF was treated with ribavirin and did not present with any symptoms of obvious hemorrhage. The child developed fever on the 5th day after the mother's onset. The partial virus genome was amplified by RT-PCR, and nested PCR from the child...

An urban epidemic of dengue in Senegal during 2009 affected 196 persons and included 5 cases of dengue hemorrhagic fever and 1 fatal case of dengue shock syndrome. Dengue virus serotype 3 was identified from all patients, and Aedes aegypti mosquitoes were identified as the primary vector of the virus.
