Dengue virus has four confirmed serotypes; infection with one type usually gives lifelong immunity to that type, but only short-term immunity to the others. Subsequent infection with a different type increases the risk of severe complications. [9]
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. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]

Dengue is typically spread through infected female Aedes aegypti (Egyptian tiger) mosquitoes that thrive in stagnant water, passing from one person to another through mosquito bites. The disease ...
Invertebrates spread bacterial, viral and protozoan pathogens by two main mechanisms. Either via their bite, as in the case of malaria spread by mosquitoes, or via their faeces, as in the case of Chagas' Disease spread by Triatoma bugs or epidemic typhus spread by human body lice. Many invertebrates are responsible for transmitting diseases.
The dengue virus spreads from person to person through the bite from an infected Aedes aegypti or Aedes albopictus ... the mosquito can transmit the virus for the rest of their one-month life span ...
In recent decades, the expansion of villages, towns and cities in endemic areas, and the increased mobility of people has increased the number of epidemics and circulating viruses. Dengue fever, which was once confined to Southeast Asia, has now spread to Southern China, countries in the Pacific Ocean and America, [39] and might pose a threat ...
