The study, published in The Lancet, found that of 76,422 participants, “21.4% experienced at least one new or increased serious symptom 3 to 5 months after infection compared to before infection.” It was found that 8.7% of uninfected people experienced it”. A study surveyed during the same period found that 1 in 8 of her COVID-19 patients in the general population (12.7%) experienced long-term symptoms from her COVID-19. suggesting. “

In a statement released Thursday, Judith Rosmalen, lead author of the University of Groningen in the Netherlands, said a study called “Persistence of physical symptoms after COVID-19 in the Netherlands” was the most frequent in long-term COVID-19. said it was investigating symptoms associated with It includes breathing problems, fatigue, loss of taste and smell, both before a diagnosis of COVID-19 and in those who have not been diagnosed with the virus.

“This method allows us to consider existing symptoms and symptoms in uninfected people to improve the practical definition of long-lasting COVID-19 and to understand the likelihood that COVID-19 will occur in the general population.” We can provide reliable estimates,” Rosmalen said.

She said there was an “urgent need” for data that could inform the magnitude and extent of long-term symptoms some patients experience after being sick with COVID-19.

“However, most of the long-term COVID studies to date have examined the frequency of these symptoms in people who have not been diagnosed with COVID-19, or examined symptoms in individual patients prior to their diagnosis of COVID-19. We weren’t,” added Rosmalen.

“Most of the data was collected before the deployment of the COVID-19 vaccine in the Netherlands, so the number of vaccinated participants was too small to be analyzed in this study,” said the press release. increase.
