We will be adding more information about Dengue shortly.
Dengue Virus
There are four serotypes (DENV-1 through to DENV-4).
DENV-1
The mildest serotype with fever like symptoms, skin rash and aching joints and bones - hence the alias name of "breakbone fever". Some research suggests that DEN-1 infection gives rise to some immunity to secondary infections of DENV-1 whilst some research also suggests that repeated infection by the dengue virus increases the likelihood of complications.
