Study results show that Omicron patients are less likely to develop Long COVID than patients with other variants

Those who had Omicron may be less likely to develop long COVID than those who had other variants, the authors of a new study from Japan concluded.

The study, published this week on the journal preprint server medRxiv, found that just one in 18 Omicron patients surveyed had long-term symptoms, versus 10 of 18 in a group of similar patients who had other COVID variants.

Symptoms were similar in those who experienced Long COVID regardless of variant, wrote the authors, who are affiliated with the National Center for Global Health and Medicine Hospital in Tokyo.

The study defined long COVID, which it calls a “post-COVID-19 condition,” as at least one symptom lasting at least two months and occurring within three months of COVID infection. Symptoms observed in patients included fatigue, difficulty breathing, cough, hair loss, depression, brain dog, difficulty concentrating, and memory problems. The researchers could not rule out alternative diagnoses that could be causing these symptoms, the report said.

The study represents the first time that long COVID epidemiological data have been examined in Omicron patients. However, more research is needed to see if the findings are applicable to Omicron patients overall, and to determine the variant’s long-term impact “on health-related quality of life and social productivity,” the paper said.

Long COVID can already affect between 7 million and 23 million Americans who have previously had the virus, or up to 7% of the US population, according to the US Government Accountability Office.

Different estimates of how many people are affected by long COVID vary widely, from 10% to 80% of COVID survivors. More than half of COVID survivors report symptoms that persist after six months, researchers at Penn State College of Medicine reported last year.

Long COVID is a poorly understood disease that could potentially affect over a billion people worldwide in just a few years, says Arijit Chakravarty, a COVID researcher and CEO of Fractal Therapeutics, a drug development company. Experts say it’s fast becoming a major public health problem, already overwhelming GPs.

What is LongCOVID? It depends who you’re talking to.

The World Health Organization defines long COVID as a condition that occurs in someone who has had COVID, with symptoms that cannot be explained by another diagnosis and that last for two months or more. Symptoms may persist after initial onset or may come and go over time, the organization says, adding that a diagnosis of long COVID is typically not made until three months after an acute illness.

The Mayo Clinic has long defined COVID as a set of symptoms arising from COVID that persist for more than four weeks after diagnosis.

In reality, long COVID is likely an umbrella term for a combination of issues and conditions: people with long-term COVID infections who are able to spread the disease further; People whose COVID after-effects wear off after a few weeks; and people with long COVID itself.

In addition, COVID patients whose illness was severe enough to require ICU admission may suffer from post-ICU complications such as muscle weakness, shortness of breath, cognitive problems, anxiety and depression – symptoms very similar to a long COVID, but not further away are the water murky. These problems can occur due to prolonged periods of immobility and the use of ventilators, as well as other traumatic medical events.

According to a landmark study published in a British medical journal in July, it seems like almost any illness – from deafness in the ear, a “brain on fire” feeling and hallucinations – could be symptoms of Long COVID The lancet.

The study identified more than 200 potential long-COVID symptoms in 10 organ systems, with 66 symptoms typically lasting longer than seven months. Researchers surveyed nearly 4,000 patients with confirmed or suspected COVID from nearly 60 countries who have been ill for a month or more.
