LOS ANGELES — From the start of the pandemic, patients and doctors alike have been frustrated by the sizable minority of coronavirus infections that turn into long COVID, a perplexing collection of lingering and often disabling symptoms that persist weeks, months or years after the initial infection subsides.
The condition has been reported in both children and adults; in those who had preexisting conditions and those in robust health; in patients hospitalized with COVID-19; and those who experienced only mild symptoms during their initial infection.
A new study from researchers at USC offers some insights into the prevalence of long COVID and suggests some early clues for who might be more likely to develop long-term symptoms.
