Dengue Virus Transmission

Mosquitoes are infected by taking blood meals from infected people. Infected mosquitoes spread the virus when biting other people.

Can you think of another biological cycle that might be important for dengue?

The dengue transmission cycle diagram. A photo of several children playing is labeled Amplification hosts with an arrow pointing to a dengue virus which points to two photos of mosquitoes biting humans. An arrow from the mosquitoes points to another dengue virus model which points back to the children playing to complete the cycle.
