BERLIN — Chancellor Angela Merkel has canceled most of her meetings for the next three weeks after doctors ordered her to rest in bed following a fall while cross-country skiing in Switzerland over the Christmas holiday, her spokesman said Monday.

Ms. Merkel had traveled to the Engadin Valley, where she regularly spends winter vacation with her family. She originally believed she had only been badly bruised after falling, but a doctor told her on Friday that she had probably suffered a pelvic fracture, Ms. Merkel’s spokesman, Steffen Seibert, told reporters.

“She fell while cross-country skiing,” Mr. Seibert said. “We do not believe she was going very fast.”

Mr. Seibert said that all of the chancellor’s scheduled travel plans had been canceled, along with several meetings in Berlin. She will continue to work from home, although she plans to lead in person the first meeting of her Cabinet when it convenes on Wednesday. “She is of course at work, and every day,” Mr. Seibert added.
