Current info from CDC says that individuals do not have to be showing symptoms to pass along the dengue virus when bitten. A very recent study looked directly at this issue.

As roughly half of all dengue infections are asymptomatic, the 252 official stat is just part of several hundred infections likely.

"The mosquito becomes infected with dengue virus when it bites a person who has dengue virus in their blood. The person can either have symptoms of dengue fever or DHF, or they may have no symptoms. After about one week, the mosquito can then transmit the virus while biting a healthy person."
