Omicron infections have a lower danger of long COVID than earlier versions, according to a research study evaluating information from 11,000 individuals.
The danger of establishing long COVID is considerably lower following an infection with the Omicron version than after an infection with earlier coronavirus versions. This was the finding of a research study by University Medication Halle, which was released in the International Journal of Transmittable Illness
The analysis took a look at info collected from 11,000 individuals about their infection history, vaccination status, and post-infection signs. The information supply strong proof that the danger for long-lasting impacts after a re-infection with the coronavirus is lower if the client did not establish long COVID after the preliminary infection.
Comprehending Long COVID and its Relation to Variations
Long-lasting signs can establish after a coronavirus infection. This is typically described as “long COVID” or “Post COVID-19 condition.” The underlying danger elements are presently under extensive examination.
” We wished to comprehend the connection in between long COVID and various coronavirus versions, vaccinations, and previous infections,” describes Sophie Diexer, very first author of the brand-new research study and scientist at the Institute of Medical Public Health, Biometry and Informatics at University Medication Halle. “Our research study reveals that the portion of individuals who establish long COVID signs after an infection was most affordable at the time when Omicron prevailed.”
The danger was discovered to be around 3 to 4 times lower after an Omicron infection than after an infection with the wild-type version. Around half of all wild-type contaminated people reported continuing signs. It must be kept in mind, nevertheless, that most of all infections took place while Omicron was dominant. “In simply mathematical terms, this implies that the majority of people established long COVID following an Omicron infection,” states Diexer.
Healing and Lowered Threat
The research study likewise supplies strong proof of a protective impact once the client has actually recuperated from a coronavirus infection. “Individuals who did not establish relentless signs after their preliminary infection had a considerably lower danger of establishing long COVID following re-infection than individuals who were contaminated with the coronavirus for the very first time. We were amazed by the scale of this impact,” describes the scientist.
Nevertheless, the researchers were not able to show that, in case of a vaccine advancement, the vaccine had any protective impact versus long COVID. Due to the timing of the research study, nevertheless, it was not possible to examine the vaccine that particularly targeted the Omicron version.
Information and Background of the Research Study
The research study is based upon the Germany-wide DigiHero job, which more than 48,000 individuals took part in till June 2022. “Research studies have actually currently taken a look at the relationship in between the danger of long COVID and the various versions, however none has actually considered infection history,” describes Teacher Rafael Mikolajczyk, director of the Institute of Medical Public Health, Biometry and Informatics at University Medication Halle.
” Of the participants, roughly 11,000 reported a minimum of one coronavirus infection that had actually taken place in the twelve weeks prior to when the information was gathered for our research study. Category was based upon the primary version at the time of the reported infection.”
Individuals were questioned about 24 common long COVID signs, with 2,822 people reporting that they had actually experienced such signs. Of these, 406 (14 percent) reported experiencing serious tiredness, 237 (8 percent) serious headaches, and 202 (7 percent) serious shortness of breath. The strength of the signs was not associated with the coronavirus version.
Future Examinations and DigiHero Task
Follow-up studies are presently being carried out to check out the perseverance of long COVID signs. “In addition to possible long-lasting signs following a coronavirus infection, DigiHero is dealing with a wide variety of health problems and other effects of the COVID-19 pandemic,” includes Mikolajczyk.
On the basis of DigiHero, University Medication Halle has actually likewise introduced the Long COVID Pc registry in cooperation with Otto von Guericke University Magdeburg and the Rechts der Isar Health center of the TUM School of Medication. The pc registry records, for instance, long COVID signs along with their development, intensity, and relief through particular treatments.

DigiHero is a Germany-wide, population-based digital health research study. To date, over 90,000 individuals from 14 German states have actually signed up. Individuals are welcomed to finish online studies that check out problems surrounding the advancement of persistent illness, healthy aging, health habits, and the coronavirus. 5 centers and 4 institutes from University Medication Halle are participating. Other job partners consist of Jena University Health center, the Leibniz Institute for Avoidance Research Study and Public Health– BIPS, and the University of Bremen.
