Women exhibited more severe symptoms than men. Among healthcare workers, palpitations were more pronounced (0.76% versus 0.35%), while the prevalence of other PCS symptoms was lower compared with non-healthcare workers. After adjusting for confounding factors, women showed a higher risk of five types of PCS, and healthcare workers had a greater risk of fatigue and dizziness compared with the non-healthcare worker. Fatigue was associated with lymphocytes, monocytes and the neutrophil:lymphocyte ratio (NLR). Cough correlated with high-sensitivity C-reactive protein (hs-CRP), NLR and the platelet:lymphocyte ratio (PLR). Dizziness was linked to hs-CRP, NLR and PLR. Palpitations correlated with hs-CRP.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Our findings
