According to the Queen, she's "weary and worn out" from having took on COVID-19. She won the battle against the infection, but it's not without some serious struggles on her part. Now that she's talking about how tired she feels in the aftermath - could she be suffering from long COVID?

The World Health Organization (WHO) defines long Covid as "usually 3 months from the onset of Covid-19 with symptoms that last for at least 2 months and cannot be explained by an alternative diagnosis." Given this definition, it might be too early to tell. But she certainly must watch out for the possibility.

During a video conference with NHS workers and patients last week, the 95-year-old monarch admitted that she the virus she got infected with last February took a toll on her.

But then she also made sure that she was not just talking about herself, but for all. The pandemic has affected everyone and made everyone feel some level of exhaustion, whether they have or have not been infected. The pandemic is not even completely over.

She told them, "It does leave one very tired and exhausted, doesn't it? This horrible pandemic. It's not a nice result."

When Buckingham Palace confirmed that the Queen had tested positive at Windsor, it was reported that she experienced "mild cold-like symptoms."

Even though she had her weekly meeting with the Prime Minister, she did not show up for any of the video calls that were scheduled. It's a great feat though for her to still show up on her duties - a mark of someone truly professional.

The cancellations, according to the Daily Mail, were made because she sounded "croaky" and "full of cold," not because her illness had worsened. She was also unable to participate in the annual Commonwealth Day service because of mobility issues.

However, it appears that the Queen, like many others who have contracted Covid, is suffering from the after-effects, including great tiredness, despite the fact that she is triple-jabbed and likely to have received her second booster injection by now.

This would only exacerbate her already-severe health issues, which necessitated hospitalization in the fall of last year and prevented her from holding an engagement outside the palace for six months.

At the end of last month, she made her public debut at the Duke of Edinburgh's Thanksgiving ceremony.

Despite the fact that she was unable to attend this year's Maundy Service in Windsor because of her mobility issues, the Duchess of Cambridge has steadfastly continued video calls and public appearances.

One former patient and some members of the hospital's staff were among those who spoke with Her Majesty this week when she opened the Queen Elizabeth Unit at The Royal London Hospital for which she serves as patron.

She appeared resplendent in a floral outfit and pearl necklace as she praised the work of the workers.

"The amount of bravery that both the patients and my colleagues showed throughout the entire pandemic was amazing and the amount of kindness we were shown was inspiring. I think we will all be bonded together because of it, forever," nurse Charlie Mort remarked.

The Queen said, "It's amazing, isn't it, what can be done when needs be."
