Reply to comment by [deleted] in 10% of patients infected early in the pandemic still had symptoms 1 year later. Common long COVID symptoms were shortness of breath (26.5%), joint pain (26.9%), loss of smell or taste (27.0%), impaired attention or concentration (22.3%), memory loss (40.0%), and sleep disorders (36.6%) by Wagamaga

From the article: “Details of new symptoms since January 2020, their duration, and whether their onset was contemporaneous with an acute infectious episode were collected.”

So they did specifically ask about the symptoms being new, and whether they started around the time of infection.

And they trust that peoples memory serve them right (especially with memory loss) and that they don't have any confirmation bias?

Any retrospective study is inherently limited by possible misremembering, which is discussed in the limitations of this study, but taken alongside findings from a swath of studies that align with this study there’s not any particular reason to believe percentages are off by any great degree. Also, for example, loss of smell or taste is a rare and remarkable symptom that people are unlikely to misremember or misattribute.
