Why is there such a large list of symptoms?
The reason for this is twofold. Firstly, each new mutation of COVID-19 brings with it a new variant. Each variant causes different short term symptoms and therefore has the potential to cause different long term symptoms as well.
This change in variant was one of the caveats listed by the authors for their study; they stated several limitations and noted the data was taken for patients infected before the arrival of Omicron.
Furthermore, other study limitations listed by the authors included:
• Data was self-reported
• A psychological evaluation of the chemosensory function was not performed
• The sample size was relatively small and geographically limited
• Patients with more severe symptoms were not included
• Data for chemosensory treatments was lacking.
As a result, the study is not considered definitive, but rather forms part of wider research in long Covid.
