![]() In most cases, anemia was mild and due to inflammation, sometimes associated with iron and/or vitamin deficiencies. In COVID-19, females had lower hemoglobin concentration than males and a higher prevalence of moderate/severe anemia (25% versus 13%, pā=ā0.032). Mortality was higher in SARS-CoV-2 positive patients. The prevalence of anemia was 61% in COVID-19, compared with 45% in a control group of 71 patients with clinical and laboratory findings suggestive of COVID-19, but nasopharyngeal swab tests negative for SARS-CoV-2 RNA ( pā=ā0.022). In an observational study, we investigated the prevalence, pathogenesis and clinical significance of anemia among 206 patients with COVID-19 at the time of their hospitalization in an Internal Medicine unit. Few data, however, are available about the prevalence and significance of anemia in COVID-19. Hematological manifestations such as thrombocytopenia and reduced lymphocyte and eosinophil numbers are highly prevalent in COVID-19 and have prognostic significance. COVID-19 patients typically present with lower airway disease, although involvement of other organ systems is usually the rule. ![]()
