Sierra Leone in West Africa is in a Lassa fever-hyperendemic region that also includes Guinea and Liberia. Each year, suspected Lassa fever cases result in submission of ≈500-700 samples to the Kenema Government Hospital Lassa Diagnostic Laboratory in eastern Sierra Leone. Generally only 30%-40% of samples tested are positive for Lassa virus (LASV) antigen and/or LASV-specific IgM; thus, 60%-70...

UNLABELLED Dengue, a leading cause of illness and death in the tropics and subtropics since the 1950׳s, is fast spreading in the Western hemisphere. Over 30% of the world׳s population is at risk for the mosquitoes that transmit any one of four related Dengue viruses (DENV). Infection induces lifetime protection to a particular serotype, but successive exposure to a different DENV increases the ...

Dear Editor, Dengue is an important arbovirus infection. This infection can result in an acute febrile illness. The important hematological abnormalities included hemoconcentration and thrombocytopenia (1). Due to the decreased platelet count, the patient might develop petechiae and hemorrhagic complication. In endemic area, the presumptive diagnosis of dengue is usually derived by the cl...

Dengue hemorrhagic fever has become a worldwide health issue. Heterologous infection by different serotypes may lead to severe forms of dengue infection and even death. In a cohort study in Jakarta from 2009 to 2010 with inclusion criteria of adults with fever of less than 48 hours, 72% were confirmed dengue infection from a total of suspected 190 dengue patients. Using RT-PCR, 16 patients were...

Background: Fluid resuscitation is the mainstay of treatment to counteract massive plasma leakage in dengue shock syndrome. We aimed to determine the differences in clinical outcomes and hemodynamic parameters of children with dengue shock syndrome post restrictive and liberal fluid resuscitation.  Materials and Methods: A retrospective observational study of pediatric patients who were betwee...

BACKGROUND Diabetes mellitus is known to exacerbate bacterial infection, but its effect on the severity of viral infection has not been well studied. The severity of thrombocytopenia is an indicator of the severity of dengue virus infection. We investigated whether diabetes is associated with thrombocytopenia in dengue-infected patients. METHODS We studied clinical characteristics of 644 pati...

During the late summers of 1927 and 1928, a biphasic dengue epidemic affected the Athens, Greece, metropolitan area; >90% of the population became sick, and >1,000 persons (1,553 in the entire country) died. This epidemic was the most recent and most serious dengue fever epidemic in Europe. Review of all articles published by one of the most influential Greek daily newspapers (I Kathimerini) du...

This thesis discusses the connection of platelet number and severity dengue hemorrhagic fever in pediatric patients Cawang UKI Hospital from January 2015 to December 2015. The data were collected medical records. research is a retrospective cross-sectional method. Total population 170 take sample 119 cases. From that, samples obtained amount decreased with increasing fever, there significant be...

Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus which transmitted through bite of Aedes aegypti and albopictus mosquitoes. mosquito, characterized sudden fever two to seven days without clear cause, weakness or lethargy, restlessness, heartburn accompanied signs bleeding on skin in form spots, bruising rashes. sometimes nosebleeds, bloody stools, vomiting blood, decreased...

Antibodies against dengue virus type 2 and 4 proteins in acute-phase sera of 10 primary and 10 secondary dengue fever and dengue hemorrhagic fever patients were studied by Western blotting. In the first group the immune response was barely detectable, while in the second group more proteins were detected, with a very strong reaction. Anti-NS1 and -NS3 antibodies were detected mainly in secondar...
