On Tuesday, Queen Elizabeth made her first public appearance since spending the night in the hospital and being advised to rest by her doctors.

Last Wednesday, the world's oldest and longest-reigning monarch, Queen Elizabeth II, remained overnight at London's King Edward VII private hospital after having "preliminary investigations" for an unexplained but non-COVID-19-related ailment.

It was Elizabeth's first overnight hospital stay in years, but she was in excellent spirits, according to royal officials, and she returned to her Windsor Castle home the next day, when she resumed minor duties.

She held two virtual audiences on Tuesday to welcome the new ambassadors from South Korea and Switzerland to the United Kingdom. During the engagement, photographs showed the monarch, dressed in a yellow gown, smiling and appearing to be herself.

Elizabeth is the queen of 15 other countries, including Australia, Canada, and New Zealand, and will mark her 70th year on the throne next year. She is noted for her good health and the fact that she still does numerous public obligations.

Last week, however, she was forced to cancel an official trip to Northern Ireland when her medical staff advised her to take a few days off.
