Dengue is a mosquito-borne viral disease that has rapidly spread across various regions of the world in the last few years. Transmitted mainly by the female Aedes aegypti mosquitoes, it is widespread across the tropics, with local variations in risk being influenced by rainfall, temperature and rapid urbanization.
While recovery from infection by one provides lifelong immunity against that particular serotype (dengue has four main serotypes), the recovery is only partial and temporary when it comes to the other serotypes. Secondary infections increase the risk of developing severe dengue.
