WASHINGTON — Justice Ruth Bader Ginsburg was admitted to Johns Hopkins Hospital in Baltimore on Friday night after experiencing chills and fever earlier in the day, a Supreme Court spokeswoman said on Saturday.

Justice Ginsburg was initially evaluated at Sibley Memorial Hospital in Washington before being transferred to Johns Hopkins for further evaluation and treatment of any possible infection, the spokeswoman, Kathleen Arberg, said in a statement.

Justice Ginsburg’s symptoms abated after treatment with intravenous antibiotics and fluids, Ms. Arberg said, adding the justice expected to be released from the hospital as early as Sunday morning.

Justice Ginsburg, 86, has had a series of health scares lately, including surgery for lung cancer and radiation treatment for pancreatic cancer in the last year. Over the years, Justice Ginsburg has also had surgery for early-stage pancreatic cancer in 2009 and treatment for colon cancer in 1999.
