Even mild COVID in young people often leads to long-term symptoms, study finds – Ars Technica

Even mild cases of COVID-19 in young individuals often result in remaining symptoms and health problems that drag on for six months or longer, according to a small Norwegian study released today in Nature Medicine.
Researchers at the University of Bergen thoroughly followed 312 individuals with confirmed cases of COVID-19 for at least 6 months. In all the age groups in between 16 and over 60 years old, in between 50 percent and 60 percent of COVID patients reported persistent symptoms.
Of those in between 16 and 30 years old, 52 percent (32 of 61) still suffered COVID-19 signs after 6 months. The most common signs were disrupted taste and/or odor, fatigue, problem breathing, trouble concentrating, and memory problems.
The research study is small, and the exact percentages may not hold up in larger studies. It adds to a growing body of data finding that long-lasting signs from COVID-19 are common– even in young individuals and/or individuals who had moderate or even asymptomatic disease.

In a non-peer-reviewed preprint study posted in March, researchers found that a 3rd of the patients recognized through medical records as experiencing so-called “long-haul” COVID-19 had initially reported asymptomatic cases. The studys authors, led by scientists in California, tracked the electronic medical records of 1,407 clients who had actually checked favorable for the coronavirus, however these people were not sick enough to be hospitalized when they were infected. Of the 1,407, about 27 percent– 382 people– developed long-lasting signs, and a third of them were at first asymptomatic.
In another study published this month, researchers tracked health insurance coverage records of almost two million individuals who checked positive for the coronavirus. The researchers found that about 23 percent of the patients sought take care of a new post-COVID medical condition one or more months later. Of individuals who had moderate to moderate cases of COVID-19 that didnt need hospitalization, 27 percent experienced persistent symptoms, as did 19 percent of individuals who initially reported asymptomatic cases.
The authors of the Norwegian research study revealed issue about finding moderate cases in young people resulting in long-term problems. “It is worrying that non-hospitalized, youths (16– 30 years old) suffer possibly extreme symptoms, such as concentration and memory issues, dyspnea and fatigue, half a year after infection,” the authors wrote. “Particularly for students, such signs might hinder their learning and study progress … Considering the millions of young individuals infected during the ongoing pandemic, our findings are a strong inspiration for comprehensive infection control and population-wide mass vaccination.”

Of the people who had moderate to moderate cases of COVID-19 that didnt require hospitalization, 27 percent experienced consistent signs, as did 19 percent of people who at first reported asymptomatic cases.
“It is fretting that non-hospitalized, young individuals (16– 30 years old) suffer possibly serious symptoms, such as concentration and memory problems, dyspnea and fatigue, half a year after infection,” the authors wrote. “Particularly for trainees, such signs might interfere with their knowing and study development … Considering the millions of young individuals infected throughout the ongoing pandemic, our findings are a strong impetus for thorough infection control and population-wide mass vaccination.”
