Hidden 'super spreaders' spur dengue fever transmission

Emory University — Thu, 23 Mar 2023 16:25:32 EST

For mosquito-borne diseases such as dengue fever, the abundance of the insects in places where people gather has long served as the main barometer for infection risk. A new study, however, suggests that the number of "hidden" infections tied to a place, or cases of infected people who show no symptoms, is the key indicator for dengue risk.
