It’s too early to know for sure, but many doctors believe there could be long-term effects from the omicron variant of the virus.
Long-term COVID is usually diagnosed weeks after an episode with COVID-19. Any lingering effects usually appear about 90 days after the symptoms of the initial infection disappear, says Maria Van Kerkhove of the World Health Organization.
Overall, some estimates suggest that more than a third of COVID-19 survivors will develop some symptoms of persistent COVID. Symptoms include fatigue, brain fog, shortness of breath, anxiety, and other problems. Prolonged illness is more likely if you are hospitalized with COVID-19, but research shows it can happen even with a mild infection.
Omicron started its round-the-world race late last year. This variant typically causes milder illness than the plain version of the coronavirus, but still overwhelms hospitals.
Van Kerkhove said she hasn’t seen any studies indicating that the fraction of COVID-19 survivors receiving long-term COVID varies by omicron variation.
Stanford University’s Dr. Linda Geng, who co-directs one of the many clinics that specialize in long-term COVID, said that while she couldn’t say for sure, it was very likely that there would be a new wave of patients.
“We have to be very cautious and very careful and prepared,” Geng said.
Meanwhile, scientists are racing to find out what’s behind the mysterious condition. Some theory? It could be an autoimmune disorder. Small microslits can cause disabling symptoms. Or perhaps the latent viruses in the body have been reactivated.
Scientists are also looking into whether vaccines could be part of the answer. A Yale University research team is investigating the possibility that vaccinations could reduce persistent COVID symptoms. And two other studies offer early evidence that getting vaccinated before a shot of COVID-19 can help prevent the disease from prolonging or at least reduce its severity.
