Transmitted through the bite of infected mosquitoes, dengue is a viral infection. Due to the type of mosquito, dengue is mainly found in tropical and subtropical climates. The dengue virus (DENV) causes dengue and has four serotypes. This means that one person can get infected and have dengue four times. There is currently no specific treatment, but around 80% of dengue cases are mild or asymptomatic. Despite this, dengue is still a very serious infection, and with half the world’s population at risk, it’s important to continue pursuing vaccine options.
