Omicron Variant Less Likely To Cause Long COVID

COVID Variant Concept

According to new research, the risk of long COVID was less during the Omicron wave compared to the Delta wave.

The SARS-CoV-2 Omicron variant is less likely to cause long COVID than the Delta variant, new research has found.

Analysis by researchers from King’s College London of data from the ZOE COVID Symptom study app is published today (June 18, 2022) in a letter to the medical journal The Lancet. The findings are from the first peer-reviewed study to report on long COVID risk and the Omicron variant.

Long COVID is defined by NICE guidelines as having new or ongoing symptoms four weeks or more after the start of the disease. Symptoms include fatigue, shortness of breath, loss of concentration, and joint pain. The symptoms can adversely affect day-to-day activities, and in some cases can be severely limiting.

Researchers found the odds of experiencing long COVID were between 20-50% less during the Omicron period versus the Delta period, depending on age and time since vaccination.

The study identified 56,003 UK adult cases first testing positive between December 20, 2021, and March 9, 2022, when Omicron was the dominant strain. Researchers compared these cases to 41,361 cases first testing positive between June 1, 2021, and November 27, 2021, when the Delta variant was dominant.

The analysis shows 4.4% of Omicron cases were long COVID, compared to 10.8% of Delta cases.  However, the absolute number of people experiencing long COVID was in fact higher in the Omicron period. This was because of the vast number of people infected with Omicron from December 2021 to February 2022. The UK Office of National Statistics estimated the number of people with long COVID actually increased from 1.3 million in January 2022 to 2 million as of May 1st, 2022.

Lead author, Dr. Claire Steves from King’s College London, said: “The Omicron variant appears substantially less likely to cause Long-COVID than previous variants but still 1 in 23 people who catch COVID-19 go on to have symptoms for more than four weeks.  Given the numbers of people affected it’s important that we continue to support them at work, at home and within the NHS.”

    It is not known that the earth will be hit by meteorites in a few thousand years.Covid-19 may not be able to destroy humans on earth in a few thousand years, but life on earth has already been destroyed by meteorites.Go to the map of the seas and continents several times.It was formed by humans tens to hundreds of millions of years ago.In the Middle East, blacks and Arabs cut off the heads of rhinoceroses.In Africa, they killed elephants for their horns.Yemen in the Strait of the Red Sea, the Red Sea, a man with his left hand holding a machete is cutting off the head of a rhinoceros.His hand and his machete are clearly visible on the map of the Red Sea and the Red Sea Strait.The continent of Africa does not look like a bull, because if it was a cow’s head, it should be In the north of Maghreb and Algeria, the horn of a cow was taken, but the horn of a rhinoceros is on his forehead, andthe horn of Africa is exactly the horn of a rhinoceros, and it is clear where the head of the rhinoceros is located, the country of Eritrea and the horn of an elephant, which if you pay close attention to the map of the country of Eritrea, you will understand.The elephant-shaped cartoon of the map of the country of Eritrea, which is located next to the map of the great country of Khartoun, and the cartoon of that huge animal, the same elephant, took the hand of a black Arab man, sothat he did not break the neck and chest of the camel, the head of the rhinoceros and the elephant, and did not injure the chest of the camel at the end of the sea.Red to the northwest of Saudi Arabia, follow the Red Sea and the Red Sea, see the tip of the black man’s machete, which is at the end of the Red Sea.There is an area near the Red Sea where the city of Giza or the city of Giza is located.In Persian, Giza is not the name of a city.Farsi Laqat dictionary, giza means wound.Do I mean a person whose body is wounded?Iranian mothers tell their children that they are wounded.Giza or giza means a wound in the Persian dictionary.America, I will explain to you that it is like a bird, and South America is like an Indian man, who is a bird flying into space, who wants to take the chief of the earth tribe with him into space, but he cannot flybecause of the impact of meteorites on the left wing of the bird.It collided while flying and the left wing of that bird is the northeast of the American continent, which is full of islands, and the right wing of the flying bird is the map of the country of Alaska, and the foot of that bird is connectedto the name of the dead head of the tribe.If you follow the country of Panama You will be connected to the face of an old man in South America.I have already explained about this important issue because it is related to the destruction of life on the planet.The sun is now located in the big arm of the galaxy, and the big arm of the galaxy is close to thousands of system objects.The stars of the arm of the galaxy are almost hundreds of times smaller than the sun.If they were bigger, the planets and stars of the large arm of the galaxy due to the force of attraction and gravity, if they were one tenth of the sun, they would not have hit the sun and the objects of the solar system.They formed the shape of four-legged animals and humans and birds, and what creatures named the countries, which is related to the topic I mentioned earlier, the sad story of the bird and the old man, and the story of cutting off the headof the average rhinoceros of humans who lived on earth a hundred million years ago.All these issues that I raised are related.You should not make fun of me.This issue is very important and it is more dangerous than the corona disease and it is related to the life of all living creatures.Dr. Mehrdad, may God protect you, keep in touch with me and share your opinions in this.Give us a message on my mobile number 00989332197646 time 16:24 pm gods py
