(Bloomberg) -- Wells Fargo & Co. is limiting employee air travel in the U.S. as companies across the country implement escalated safety measures amid the spread of the coronavirus.

“Out of an abundance of caution, we are now restricting all non-essential business air travel in the United States, and requiring executive-level approval for any business air travel deemed essential,” Wells Fargo spokeswoman Beth Richek said in a statement. The bank had earlier restricted international business travel.

Banks around the world have been working to ensure they can keep their businesses running as the virus spreads by restricting travel, splitting up teams and traders amid different locations, and quarantining staff. Coronavirus cases have reached at least 96,445 globally, and the death toll has surpassed 3,300.
