1. Zika will spread only if the following factors are present:

  • A human must be carrying the virus at the time of contact
  • Aedes aegypti mosquitoes need to be on hand to carry it to others

2. The U.S. cities most at risk:

  • Miami
  • Orlando, Florida
  • Savannah, Georgia
  • Charleston, South Carolina

These cities are reportedly at even higher risk than Houston, which has mosquito control programs underway to stop the Zika infection, according to the team reports in the Public Library of Science journal PLOS Currents Outbreaks.

To reduce your own risk against mosquito bites, use an insect repellent registered by the Environmental Protection Agency.
