The dollar fell against the yen and the Swiss franc on Thursday after the first coronavirus infection of unknown origin was confirmed in the United States, adding to fears of a pandemic.
The dollar also fell from a three-month high versus the pound and declined versus the euro as 10-year U.S. Treasury yields crashed to a record low as concerns grew over whether the world's largest economy was prepared for the epidemic.
Other currencies were locked in narrow ranges as traders nervously monitor the global spread of the coronavirus that emerged in China late last year.

The dollar also fell 0.35% to 0.9735 Swiss franc, a currency that is traditionally sought as a safe haven.
