Humans infected with the Omicron variant of coronavirus are less likely to develop long-term Covid, according to a study conducted at King’s College London, England, published Thursday (16/6) in The Lancet.
By analyzing UK patient data stored in the Zoe Covid Symptom Study, the researchers found that the chances of developing the condition during the current wave of the pandemic are 20% to 50% lower compared to the Delta wave.

Without having a definite name, the set of symptoms that continues after the coronavirus infection is cured is called Post-Covid Syndrome, Long Covid, Persistent Covid, or Long-Term Covid. freepik

Long-term Covid is defined as cases where the symptoms of the infection last for more than 4 weeks. Some other patients also recover quickly, but have long-term problems. Pixabay

One of the latest and most comprehensive articles on the subject is from a group of universities in the United States, Mexico and Sweden. The researchers selected the most relevant publications on long-term Covid around the world and identified 55 main symptoms. iStock

Among the 47,910 patients who participated in the studies, the five main symptoms detected were: fatigue, headache, attention deficit, hair loss, and difficulty breathing. Getty Images
Prolonged Covid is also common after mild and moderate versions of the infection without the patient needing hospitalization. About 80% of the people who got the disease still had some symptoms for at least two weeks after curing the virus.freepik

Experts believe that the long Covid may be a “second wave” of the damage caused by the virus on the body. The first infection causes some people’s immune system to become overwhelmed, attacking not only the virus but the body’s own tissues. Getty Images
So far, there is still no adequate treatment for this clinical condition that occurs after recovery from Covid-19. The main focus is on controlling symptoms and gradually increasing daily activities.Getty Images
Despite a full recovery from the disease, recent studies from the University of Washington in Saint Louis in the United States warn that anyone who has recovered from Covid-19 may suffer from complications in the year following infection.Getty Images
Data from 150,000 people who had the virus were analyzed to arrive at the most common complications. Getty Images
For example, the risk of having a heart attack is 63% higher for those who have already had the infection. The chance of coronary artery disease increases to 72%, and for a heart attack 52%Getty Images
It also draws scientists’ attention to the increase in the number of patients with depression and anxietyGetty Images

Among the 56,003 cases investigated during the peak of Ômicron in the UK, between December 2021 and March 2022, 4.5% of people reported symptoms of prolonged Covid. In the previous wave, between June and November 2021, 10.8% of the 41,361 infected patients did not fully recover.
Values varied depending on the age of the patients and the time at which they took the last dose of vaccines and compared unvaccinated and unvaccinated individuals.
This is the first study to show that the Ômicron variant represents a lower risk of developing comorbidities that involve, for example, prolonged fatigue, shortness of breath, muscle aches, joint pain, loss of smell and taste, and mental confusion. However, researchers warn that the risk still exists.
“This is good news, but do not disable any of your Covid precautions,” lead study author Claire Steves told Reuters in an interview with the agency.
