How many viruses does dengue have?
Dengue is caused by one of any of four related viruses: Dengue virus 1, 2, 3, and 4.
How are dengue viruses classified?
Dengue is classified as (1) undifferentiated fever, (2) dengue fever (DF), and (3) dengue hemorrhagic fever (DHF). In addition to fever and at least 2 clinical findings, diagnosis of DF requires epidemiological or laboratory evidence supporting a dengue virus infection.
What is dengue type 2?
Native Dengue Virus Type 2 is a preparation of viral particles concentrated from tissue culture supernatant. Dengue Virus Type 2 is one of four antigenically distinct yet closely related viral serotypes belonging to the family Flaviviridae known to cause Dengue fever in humans.
Is dengue virus a retrovirus?
The difference in abundance between the two areas does not affect the impact of dengue virus on humans (10). Since, DENV is a retrovirus, it follows the traditional retroviral infection pathway This means turning its RNA into host cell DNA and then making copies from the host machinery.
What are the 4 serotypes of dengue?
The Dengue Serotypes Dengue infections are caused by four closely related viruses named DEN-1, DEN-2, DEN-3, and DEN-4. These four viruses are called serotypes because each has different interactions with the antibodies in human blood serum.
How many types of dengue strains are there?
There are four dengue virus serotypes (DENV-1, DENV-2, DENV-3 and DENV-4), meaning that it is possible to be infected four times. While most infections produce only mild illness, dengue virus can cause an acute flu-like illness. Sometimes this develops into severe dengue, which is blamed on the DENV-2 type.
What are the three types of dengue?
There are four serotypes (DENV-1, -2, -3, and -4), and the virus is transmitted to humans through the bite of mosquitoes of the genus Aedes (5). DENV causes a wide spectrum of clinical manifestations, from DF to dengue hemorrhagic fever (DHF), which may progress to dengue shock syndrome (DSS) (20, 43).
