ST. PAUL, Minn. (AP) _ Kitty Dukakis, wife of Democratic presidential nominee Michael Dukakis, was hospitalized Monday night with a viral infection and a 102-degree fever, said a campaign spokesman.

Mrs. Dukakis was admitted to the University of Minnesota Hospital shortly before 10 p.m. after complaining of fever and chills, said Paul Costello, her press secretary. She was expected to stay overnight for observation and tests, he said.

Mrs. Dukakis, 51, began to experience the fevers and chills after she had dinner with her staff and Secret Service agents at the St. Paul hotel where she was staying while on a campaign swing for her husband, Costello said.

She was taken to the hospital by the Secret Service agents.

Earlier in the day, Mrs. Dukakis underwent tests after admitting herself into the hospital about 7 a.m. Doctors prescribed antibiotics for the viral infection and Mrs. Dukakis returned to the hotel, where she rested all day, Costello said.

Costello said Mrs. Dukakis spoke with her husband briefly Monday night. He said there was no plans for the candidate to visit his wife.
