It’s too early to know for sure, but many doctors believe it’s possible to have long-term effects from the omicron variant of the virus. Long COVID is usually diagnosed many weeks after a bout with COVID-19. Any long-lasting effects typically appear about 90 days after symptoms of the initial infection go away, Maria Van Kerkhove of the World Health Organization said this week.
Overall, some estimates suggest more than a third of COVID-19 survivors will develop some symptoms of long COVID. Symptoms include fatigue, brain fog, shortness of breath, anxiety and other problems. The lingering illness is more likely if you’ve been hospitalized with COVID-19, but research shows it can happen even after a mild infection.
Omicron began its race around the world late last year. The variant generally causes milder illness than the delta version of the coronavirus, but has still overwhelmed hospitals.
Van Kerkhove said she hasn’t seen any research indicating that the portion of COVID-19 survivors who get long COVID will change with the omicron variant.
