How many people get 'long Covid?' More than half, researchers find

It may be difficult to crunch convincing numbers when concepts are fuzzy and aggregative and time related, but this is one "value key" of those which seemed to swing more wildly in "these long tiring months".

Three British studies, near in time, put to "chance of long covid after infection" the values of 2.3%, 13% and 40%, another article (mentioned in these pages) indicated 25% (as the component with cognitive symptoms 8 months after infection).

The linked divulgative commentary considers the data from 250'000 unvaccinated adults (~80% hospitalized) diagnosed with covid19 from Dec 2019 to Mar 2021. The "length of symptoms", I understand, should be of six months or longer (though some phrasing is not really clear, e.g. «manifestations ... rates remained largely constant from one month through six or more months after their initial illness»). It is more interesting than others as it disaggregates the symptoms:

> General well-being (~50%): More than half of all patients reported weight loss, fatigue, fever or pain.

> Mobility (~20%): Roughly one in five survivors experienced a decrease in mobility.

> Neurologic concerns (~25%): Nearly one in four survivors experienced difficulty concentrating.

> Mental health disorders (~33%): Nearly one in three patients were diagnosed with generalized anxiety disorders.

> Lung abnormalities (imaging: ~60% ; breathing: ~25%): Six in ten survivors had chest imaging abnormality and more than a quarter of patients had difficulty breathing.

> Cardiovascular issues: Chest pain and palpitations were among the commonly reported conditions.

> Skin conditions (~20%): Nearly one in five patients experienced hair loss or rashes.

> Digestive issues: Stomach pain, lack of appetite, diarrhea and vomiting were among the commonly reported conditions.

It's really worrying
