The first time a person is infected with a dengue virus, they usually have a milder form of the disease called dengue fever. The typical symptoms are fever, headache, joint and muscle pain, and a.
In 2004, a major epidemic of dengue infection occurred in Sri Lanka, which accounted for 15 457 cases and 88 deaths. The findings from recent studies on dengue are outlined here, which highlight the implications with regard to the management and control of this infection in the country.
As dengue is a “viral hemorrhagic fever”, the disease is under European surveillance. It is by far the most important mosquito-borne viral disease affecting humans worldwide; tens of millions of cases occur each year resulting in approximately 20,000-25,000 deaths mainly in children. There are four serologically distinct dengue viruses, so people living in a dengue-endemic area can have.
Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. Five serotypes of the virus have been found, all of which can cause the full spectrum of disease. Nevertheless, scientists' understanding of dengue virus may be simplistic, as rather than distinct antigenic groups, a continuum appears to exist.
Dengue fever is a mosquito-borne viral disease caused by 1 of 4 closely related but antigenically distinct serotypes of dengue virus, serotypes DENV-1 through DEN-4. (17) Infection with one dengue serotype confers lifelong homotypic immunity and a brief period of partial heterotypic immunity (2 years), but each individual can eventually be infected by all 4 serotypes. Several serotypes can be.
Instances of extreme disease severity are characterized by cytokine storm, life-threatening vascular leakage syndrome, and hemorrhagic fever or shock. 69 Immune control of dengue virus, particularly in the context of a heterologous strain challenge, can be enigmatic as cross-strain reactive antibody and memory T cell responses often amplify viral replication and associated pathology. 69.
Dengue is caused by one of four viral serotypes (closely related viruses), designated DEN-1, DEN-2,. In 2008 the World Health Organization reported that approximately 2.5 billion people worldwide were at risk of dengue and that the disease was endemic in more than 100 countries. From 2010 to 2016 the number of dengue cases recorded globally increased from 2.2 billion to 3.34 billion. Cases.
A viral disease (or viral infection, or infectious disease) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. Viral disease; Specialty: Infectious disease: Structural characteristics. Basic structural characteristics, such as genome type, virion shape and replication site, generally share the same.
Dengue is a mosquito-borne viral infection that usually causes a self-limited febrile illness, but can give rise to dengue hemorrhagic fever or dengue shock syndrome. There are currently no specific treatments, though a vaccine was recently licensed for use in limited countries. Dengue’s geographic range is ever-increasing, with an estimated global burden of 50 to 100 million infections per.
Dengue fever is an acute febrile disease caused by infection with one of the serotypes of dengue virus. It is a mosquito-born disease caused by genus Aedes. Dengue is also known as Breakbone Fever, Hemorrhagic Fever, Dandy Fever, Infectious Thrombocytopenic Purpura. Dengue hemorrhagic fever is a fatal manifestation of dengue virus that manifest with bleeding diathesis and hypovolemic shock.
