The U.S. will begin screening Friday night for the novel coronavirus, originally found in Wuhan, China, for flights arriving directly or indirectly from there to three American airports — San Francisco, New York and Los Angeles, public health officials announced.

Why it matters: Researchers still don't know the source of the "2019-nCoV" virus or how it's transmitted, but coronavirus' ability to evolve means the outbreak could quickly turn from "worrisome to extremely worrisome," and "proactive measures" should be taken, Nancy Messonnier told a press conference.

There are 2,668 confirmed hospital cases of lung injury associated with vaping in all 50 states, Washington, D.C. and two U.S. territories, the Centers for Disease Control and Prevention reports as of Jan. 14.

What's new: Nationally, most vaping-related patients with data on how they sourced products reported obtaining THC-containing products from "informal sources," per the CDC. The agency now recommends users should consider no longer vaping THC products, rather than its original claim to refrain from e-cigarettes.
