Carly Fiorina, the California Republican candidate for U.S. Senate, has been successfully treated for an infection and was released from a hospital on Wednesday, her staff said.
Fiorina, a former Hewlett-Packard chief executive who underwent surgery for breast cancer in February 2009, developed the infection following reconstructive surgery this summer. She was admitted on Tuesday to an undisclosed hospital, where she remained overnight for observation, her chief of staff said.
A campaign statement on Wednesday morning said Fiorina had been treated successfully and would be returning to the campaign trail.
A campaign spokesman said on Wednesday evening that the Republican nominee had been discharged and would resume her public appearances on Thursday with a stop in Sacramento.
The medical setback came at a bad time for Fiorina, less than a week before California voters cast their ballots as part of the U.S. congressional elections on November 2.
Recent opinion polls show Barbara Boxer, a powerful liberal voice in the Senate and strong supporter of President Barack Obama, running neck-and-neck with Fiorina, a political novice making her first run for public office.
Political analysts have called the race a toss-up despite California's reputation as a solidly Democratic state, saying voter dissatisfaction and the state's high unemployment rate have left Boxer vulnerable.
