Kim Thomas felt drawn to being a home health aide after caring for her own ailing mother. Human dignity, she says, can be simple, like a bath and a favorite snack.

When Thomas first started visiting homes to care for patients, she made $7 an hour. That was in North Carolina about 16 years ago. Her pay inched up over time, to $10.50. To try to make ends meet, she sometimes would work through the night, dozing in patients' homes.

Hours after the White House rejected the idea of appointing a coronavirus czar, President Trump on Wednesday put Vice President Pence in charge of the administration's response to the disease.

"We're doing really well, and Mike is going to be in charge," Trump said, noting that Pence's experience as governor of Indiana made him adept at working with state and local health authorities.

"This is not a czar," the president later added.

As fears spread of a wider coronavirus outbreak in the U.S., experts in global health pandemics as well as some of President Trump's leading political adversaries contend that the federal government's response may be lacking a key figure: a coronavirus czar.
