Senator Robert Byrd is Admitted to the Hospital After Experiencing a Fever due to an Infection

Sen. Robert Byrd (D-W.Va.), 91, has been hospitalized again, according to his office.

The oldest and longest serving senator in U.S. history was admitted late Friday afternoon with a "spike in his temperature" caused by a "minor infection," according to the statement from his office, which did not identify which hospital.

Spokesman Jesse Jacobs says the senator is "responding well" to antibiotics and is expected to be released from the hospital in a few days.

Sen. Robert C. Byrd, 91 and the longest-serving senator in history, was hospitalized last Friday with a temperature spike evidently caused by a minor infection, his office announced Monday.

Byrd, a West Virginia Democrat, "is being treated with antibiotics, responding well and is expected to be released from the hospital in a few days,'' the office said in a statement.

Byrd has been in Congress since 1952 and was first elected to the Senate six years later.

On May 18, 2009, Sen. Byrd was admitted to the hospital after having a fever due to a “minor infection.” But his stay there was prolonged due to a staphylococcal infection. He was then released on June 30, 2009.
