RT’s Three Key Takeaways:
- Repeat Infections Improve Lengthy COVID Threat: A four-year examine discovered that just about 85% of sufferers with lengthy COVID had a number of COVID-19 infections, highlighting a powerful hyperlink between reinfections and the chance of creating persistent signs.
- Vaccination Reduces Lengthy COVID Threat: Vaccination earlier than contracting COVID-19 considerably lowered the danger of creating lengthy COVID.
- Examine Supplies Foundational Information on Lengthy COVID: The examine tracked 475 lengthy COVID sufferers over 4 years, providing insights into the situation’s development, danger elements, and protracted signs corresponding to fatigue, respiratory points, and neurological challenges.
A brand new examine that recognized 475 sufferers with post-acute sequelae of COVID-19 (PASC), often known as lengthy COVID, revealed that just about 85% of those sufferers had a number of COVID-19 infections over the course of a four-year interval (March 2020 to February 2024).
Moreover, vaccination independently diminished the danger of lengthy Covid in sufferers who had acquired the vaccination previous to contracting the an infection.
Performed by a staff of researchers within the Renaissance College of Drugs at Stony Brook College, along side the Stony Brook World Commerce Heart Well being and Wellness Program, the examine might function a foundational evaluation of lengthy COVID sufferers within the post-pandemic period. So far, there are few research with such a affected person pattern dimension that examine what places sufferers in danger for lengthy COVID and what causes this power situation.
The findings are printed early on-line within the February version of The Lancet Regional Well being – Americas.
Signs and Diagnostic Challenges
“Whereas it’s potential that the causes of lengthy COVID could possibly be many and variable relying on the affected person inhabitants studied, with this cohort the proof is obvious that by having COVID quite a few instances, sufferers grew to become extra at-risk for creating lengthy COVID,” says lead writer Sean Clouston, PhD, professor within the division of household, inhabitants, and preventive drugs within the Renaissance College of Drugs and program in public well being, in a launch.
He provides that after adjusting for related demographic, way of life, and medical variables, the findings reveal a statistically important affiliation between experiencing a number of COVID-19 infections and the danger of experiencing lengthy COVID.

The sufferers have been recognized from a bunch of greater than 2,500 first responders who beforehand had COVID and are prospectively monitored for an infection issues by the Stony Brook World Commerce Heart Well being and Wellness Program. The 475 recognized with lengthy COVID by this system’s physicians, led by Benjamin Luft, MD, director of this system, regularly skilled lengthy COVID signs starting from fatigue, psychological fog, different neurological situations, in addition to a number of respiratory issues and gastrointestinal signs.
Significance of Future Analysis
Provided that a number of the first responder sufferers have had signs over time associated to their environmental exposures, corresponding to respiratory diseases, lengthy COVID signs have been recognized and charted individually and after every subsequent COVID an infection.
Since there is no such thing as a diagnostic check for lengthy COVID, the researchers adopted the World Well being Group’s pointers for figuring out lengthy COVID. They recognized contributors with lengthy COVID as having skilled the continuation or growth of a minimum of one new symptom that emerged inside three months after their preliminary COVID-19 an infection and endured for a minimum of two months with out different concurrent medical rationalization. In distinction, these with out such experiences after having COVID have been positioned within the non-long COVID group.

“There are some potential pathogenic mechanisms that trigger lengthy COVID, however your entire spectrum of its danger elements stays unknown,” says Luft, a co-author, the Edmund D. Pellegrino Professor of Drugs within the Renaissance College of Drugs and an infectious illnesses specialist, in a launch. “That is why our examine and future ones are so essential. Figuring out particular danger elements corresponding to re-infection or lack of vaccination can help in higher understanding and managing the situation.”
The authors level out that the most secure solution to keep away from contracting lengthy COVID is to forestall the an infection within the first place. Nonetheless, they emphasize that the function of vaccination within the danger of creating lengthy COVID can’t be underestimated. They wrote, “Amongst those that later developed PASC, we discovered that the danger of PASC was a lot greater amongst people who have been unvaccinated on the time of their first (COVID-19) an infection.”
