The rapid spread of the highly contagious variant of omicron continues to cause concern around the world, including for many people who have already suffered a coronavirus attack.
Compared to other variants, omicron may have an increased risk of re-infection, the World Health Organization said, noting that the information was limited and based on preliminary evidence.
But can you be infected with omicron twice?
At this point, it’s uncertain.
“The question of whether you can be re-infected with the same strain of COVID-19, and how likely it is, is open,” according to an article by Dr. Michael Dreis in GoodRx Health.
Dr Amesh Adlja, a senior researcher at the John Hopkins Center for Health Security, told KHOU-TV in Houston that it is not clear what level of immunity occurs after an omicron infection.
“I think over time, yes you can probably get re-infected,” he said. “But we don’t have that data yet because omicron has only been around since October / November.”
In mid-December, a study in the UK found that the risk of reinfection with the omicron variant was more than five times greater than delta, Reuters reported.
The Imperial College London study found no evidence that the gravity of omicron was different from that of delta. However, some researchers have argued that it is important not to overinterpret the results, saying sufficient data is not yet available.
Overall, some doctors say the newer variants are of “great concern” for reinfection.
Because the new variants are extra-contagious and vaccine immunity wanes over time, more re-infections have been reported in recent months, according to doctors at the Cleveland Clinic, noting that relaxed COVID-19 precautions have also played a role.
Department of Public Health Commissioner Dr. Allison Arwady explained what you need to know about the different mask options (cloth, surgical, KN95, and N95) and which mask you should wear.
While the omicron variant has become the dominant strain in the United States, the coronavirus in general does not mutate as much as the flu, which changes in appearance about every year, according to Dr. Frank Esper, a pediatric infectious disease specialist in Cleveland. Clinical.
Rather, it is his contagiousness that sets him apart from others.
“The infectivity of this variant – including its ability to evade the immune system and prevent long lasting immunity for those infected – is one of the reasons it was able to persist and come back,” he said. he declares.
