In a recent study posted to the medRxiv* preprint server, researchers in the Netherlands examined the role of inflammatory genes, cytotoxic T-lymphocytes (CD8+ T cells), and pro-inflammatory cytokines in long-lasting severe fatigue experienced by a large number of coronavirus disease 2019 (COVID-19) patients. Study: Severe fatigue as symptom of long COVID is characterized by increased … Read more
