Florida identifies two more Zika cases not related to travel

The Florida health department said on Wednesday it is investigating another two cases of Zika not related to travel to a place where the virus is being transmitted, raising the possibility of local Zika transmission in the continental United States. The health department said it has identified an additional case of Zika in Miami-Dade County, where it was already investigating a possible case of Zika not related to travel, and another case in Broward County, where it has been investigating a non-travel related case. To confirm whether Zika is being transmitted locally, epidemiologists must survey households and neighbors within a 150-yard radius around the residence of the person who has Zika, which constitutes the flying range of the mosquitoes that carry the virus.
