(Bloomberg) -- Senator Dianne Feinstein of California, the chamber’s oldest member, has been hospitalized in San Francisco with a case of shingles.

Feinstein, 89, who announced last month that she would not seek reelection, said in a one-paragraph statement Thursday that she expects “to make a full recovery. I hope to return to the Senate later this month.”

The statement provided no other details, other than to say she had been “diagnosed over the February recess.”  

Her decision not to run in 2024 came after several years of speculation about whether she would continue in office, and as other California lawmakers showed interest in running for her seat. Feinstein has yielded some key roles in the last few years.

Already, several Democrats have jumped into the race to succeed Feinstein, who was first elected in 1992, and more are looking eagerly from the sidelines. Representatives Barbara Lee, Adam Schiff and Katie Porter have already announced their candidacies.
