Transcript for Queen Elizabeth's Latest Health Concerns
It's been weeks since she's been seen in public. They say she's missed many public events because of a cold. Lama Hasan is in London with the story. Reporter: This is a very important time of the year for the queen. She's normally front and center of all the royal celebrations but what the palace is calling a heavy cold has kept the queen out of the public eye. For the 1esecond week in a row, the queen was a no-show at church after a bad cold forced her to skip the traditional new year's day service and the family's annual Christmas service at sand ring ham. Buckingham palace releasing a short statement saying the queen does not yet feel ready to attend church. Princess Anne said the queen was feeling better. Her husband said she's doing not too bad so we can conclude from that that they wouldn't be speaking in the public in this manner if she was struggling. Reporter: She is still active and tries to carry out as many engagements as possible. She has significantly reduced the number of official long haul trips, and just last month the monarch handed over 25 of her 600 patronages, charities and organizations to other members of the royal family. The last time the queen was seen was on December 14th, prerecording her Christmas message. I often draw strength from meeting ordinary people doing extraordinary things. Reporter: Now that the queen has been out of sight for more than two weeks, fears are growing about her health. Royal sources are trying to reassure the public, saying she's up and about, attending to her papers, but inside the warmth of her home. We are talking about a 90-year-old woman with a lingering cold. She didn't want to be standing inside a cold church for up to an hour braving that terrible rain and didn't want to risk getting worse. And she was advised by her doctors to not take the risk. Reporter: The queen and Phillip postponed their Christmas trip aboard the royal train and took the royal helicopter 24 hours later to their winter retreat. George and Charlotte, as usual, stole the show this year, spending Christmas with the middletons, candy canes in hand, showing Santa they weren't naughty but nice. But uncle Harry did spend the holidays with the queen and other Royals at sandringham away from his American sweetheart, Megan Markle. Buckingham palace telling ABC news this morning the queen is up and about, still receiving those red boxes which are official government documents she gets every day and we could see her this Sunday at church. No sign the queen has been hospitalized, right? Reporter: No, you're absolutely right. Our understanding is the queen has not been to the hospital yet. She's not had any tests done. All we are being told is she is suffering from a heavy cold, George? We hope she gets well soon.
