Dengue is an infectious disease which means that it is caused by tiny pathogenic (harmful) organisms and can be contagious or spread among people upon contact with an infected person.
Dengue fever is actually caused by four serotypes of mosquito-borne dengue virus (DENV 1-4), positive-sense RNA viruses belonging to the genus Flavivirus.
DENV-human host-mosquito vector interactions are complex and cause in humans either asymptomatic or subclinical DENV infection, mild to severe dengue fever (DF)m severe dengue hemorrhagic fever (DHF), or dengue shock syndrome (DSS).
Dengue fever is transmitted by humans by the bite of an infected mosquito. Transmission means the virus is being passed or spread to someone else.
A major breakthrough on the treatment is dengue fever came in 1944 when Dr. Albert Sabin isolated and identified the dengue fever.
Disease due to DENV usually manifests in a 2-7 day fever with coincident high titers of viremia; additional symptoms include headache, retro-orbital pain, nausea, myalgia, arthralgia, weakness and rash.
