59 people have been diagnosed with novel coronavirus in the U.S., an increase in cases largely driven by the repatriation of American citizens from the cruise ship Diamond Princess in Japan, the Centers for Disease Control and Prevention said Wednesday.

The big picture: As more countries experience community-wide transmission, CDC official Dr. Nancy Messonnier told reporters Tuesday that it's now a question of when the same will happen in the U.S. — and how many citizens will develop a severe illness.

  • Two of the cases were contracted through person-to-person contact.

What's happening: The CDC outlined standard public health measures to mitigate spread of the virus on Tuesday, including what closing schools and businesses would look like in a U.S. pandemic.

  • "We really want to prepare the American public for the possibility that their lives will be disrupted," Messonnier said.
  • Schools and workplaces may need to explore tele-commuting and online assignments. Hospitals also may need to regroup patients.

Senate Judiciary Committee Chair Lindsey Graham (R-S.C.) told Fox News Saturday he expects confirmation hearings on Judge Amy Coney Barrett's nomination to the Supreme Court to start Oct. 12 and for his panel to approve her by Oct. 26.

Why it matters: That would mean the final confirmation vote could take place on the Senate floor before the Nov. 3 presidential election.

Texas authorities have issued a warning amid concerns that the water supply in the southeast of the state may contain the brain-eating amoeba naegleria fowleri following the death of a 6-year-old boy.

Details: The Texas Commission on Environmental Quality issued a "do not use" water alert Friday for eight cities, along with the Clemens and Wayne Scott Texas Department of Criminal Justice corrections centers and the Dow Chemical plant in Freeport. This was later lifted for all places except for Lake Jackson, which issued a disaster declaration Saturday.
