Covid-19: Omicron variants reduce the severity of the disease, so can there be a risk of long covid in infection?


These days the cases of corona infection are increasing in many countries of the world including China-America. Along with the cases of infection in China, the number of dead is also being seen more. At the same time, due to infection in America, this time people have to be admitted to hospitals as well. At present, only cases of Omicron and its sub-variants of Corona have been reported in most countries.

The researchers found that most of the Omicron variants have a high infectivity rate but are mild in nature. That is, the risk of severe symptoms may be reduced in case of infection with Omicron variants. Such dangers are being seen only in those people who are either victims of comorbidity or have not been vaccinated.

The risk of severe disease in case of transmissibility from Omicron variants is low, the researchers said. In such a situation, the question arises whether there can be a risk of long covid or post covid problems in those infected with it? Let us know what the studies have revealed about this?

Know about Long Covid

Before knowing about the danger of long covid after infection with Omicron variants, it is necessary to understand what is long covid?

According to health experts, even after recovery from Kovid-19 infection, some people are seeing various health problems for a long time, this is known as long or post covid syndrome. Especially after infection with the delta variant of Corona, more cases of long covid were seen, in which fatigue-weakness, respiratory problems, etc. remained in people for a year after recovering from the infection. Compared to the delta variants causing more severe disease, the risk of severity in infection with Omicron is much lower. So can those infected with it also become victims of long covid?

What did the study find?

Nature Communications Journal In a study published in , researchers tried to determine the risk of post-covid syndrome complications in those infected with the Delta and Omicron variants. For this, Omicron infected people aged 18 to 70 years were included. Using the whole genome and sequencing data of participants, the study was conducted to determine their risk of long COVID based on symptoms of infection.

In the results of this multi-stage study, the researchers found that individuals with Omicron infection may also be at risk of long covid like delta infections. Post Covid problems include fatigue, shortness of breath, cough, anxiety, depression and irregular heartbeat. The risk of long Covid complications can range from 14 days to 126 days. However, those infected with the Omicron variant reported fewer long-term complications after 90 days than those infected with the delta variant.

Effect of vaccination on long covid

Is there a risk of long covid even in vaccinated people? To know about this, a UK study at the end of the year 2021 has shown that vaccination can reduce such danger. Research found that people who took both doses of the vaccine were found to have a 40 percent lower risk of post-covid problems than others. The risk has been found to be less in those with a booster dose.
