A survey carried out at St Gallen Hospital, Switzerland, points out that people infected by the coronavirus at the beginning of the pandemic were more likely to develop long Covid when compared to those infected by the wave of the Omicron variant.
The research used the medical information of 1,200 health professionals, their average age was 43 years. Doctors, nurses and aides underwent regular testing for Covid-19, with nasal swabs and antibody tests.
All study participants caught the disease at least once, either from the version of the original that circulated at the beginning of the pandemic, the Omicron variant or both strains.
Over a period of one year and six months, participants answered three questionnaires regarding the symptoms they were experiencing. Symptom options included loss of smell and taste, tiredness and weakness, burnout and exhaustion, and hair loss.
Conclusion
The study, which will be presented at the European Congress of Clinical Microbiology in April, concluded that healthcare professionals infected with the original virus were up to 67% more likely to experience symptoms of the long Covid. Those infected with Omicron, in turn, had a significantly lower chance of having symptoms following the disease.
“With Omicron still dominant globally today, our results should provide safety for those who are contracting Covid-19 for the first time, as well as for those who already had the wild-type virus”, points out researcher Carol Strahm, author of the work .
