Background: Anemia commonly aggravates the severity of respiratory diseases, whereas thus far, few studies have elucidated the impact of anemia on coronavirus disease. Anaemia can also occur as a protective mechanism in certain acute immune activation, to prevent the virus from invading the organs. Aim: The aim of this study was to evaluate the covid 19 patients with anemia, and to further explore the relationship between anemia and the severity of COVID‐19. Materials and Methods: In this single‐center, retrospective, observational study, a total of 972 confirmed patients admitted to Govt Medical College Ernakulkam, were grouped into 3 classes A, B, C according to their severity & Hb level was estimated & recorded. Data was analysed by descriptive statistics and results reported as mean and SD or median and interquartile range (IQR), depending on each variable value distribution, differences between groups. Results: Anaemia was significantly related to comorbidities present during admission, severity class & complications. Decrement in Hb level was seen in patients who had a very serious disease & poor outcome. Conclusion: Anemia is an independent risk factor associated with the severe illness of COVID‐19, and healthcare professionals should be more sensitive to the hemoglobin levels of COVID‐19 patients on admission. Awareness of anemia as a risk factor for COVID‐19 is of great significance. |
