The Queen is expected to resume her royal duties next week after a brief illness.

Buckingham Palace officials said today  the queen and her husband Prince Philip  plan to attend a Westminster Abbey service Monday to mark Commonwealth Day with another event scheduled later in the week.

86-year-old Elizabeth was hospitalized overnight on Sunday for treatment of gastroenteritis.

It was her first hospitalization in a decade.

Officials say the queen’s overall health remains good and she is not cutting back on her activities although taxing overseas travel has been reduced.

91-year-old Philip has been treated for heart disease in recent years.

He has said he plans to attend fewer events and to scale back his charity events.
