The Centers for Disease Control and Prevention said this week that it does not know how a man in Utah got the Zika virus. He didn't travel outside the U.S., or have sex with anyone who had Zika, and the mosquitos that carry the virus don't typically live in Utah. So far, his only known contact with the virus was in caring for his elderly father, who had contracted Zika while traveling.
Also this week, the Florida Department of Health announced it's investigating its first possible case of local transmission of the virus. Here & Now's Meghna Chakrabarti gets the latest from Helen Branswell, who covers infectious diseases and public health for STAT, the national health and medicine publication.
