“The greater the control of the disease and the lower the number of cases, the lower the chances of the individual becoming infected. The mosquito, to transmit dengue, needs to bite someone who is already infected, which creates a transmission cycle in which the mosquito transmits from one person to another”, explains Kfouri.
“The opposite is also true. It ends up being a geometric progression: the combination of many cases and many mosquitoes is what makes the number of infected increase exponentially.”
