All pregnant women in the U.S. should be tested for exposure to the Zika virus, the Centers for Disease Control said Monday. The development comes on the same day as Florida Gov. Rick Scott announced that 10 more people were infected by the virus through mosquitoes. Florida officials have advised pregnant women to stay away from the Wynwood neighborhood in Miami. Zika can be spread through sexual contact in addition to mosquitoes in warm climates. The Florida cases are the first to be contracted on the U.S. mainland.
