However, controversies still exist. In addition, there is little data to show if Absolute Eosinophil Count (AEC) would start to show a rising trend during patient’s road to recovery. This study hypothesized that AEC values would start to return towards normal as patients recovered from this illness. This study included 43 patients with Covid-19 infection treated in the ICU at Khoula Hospital, Muscat from 10th of May to 5th of August 2020. Seven readings of Absolute Eosinophil Count (AEC1 to AEC7) from the time of admission (AEC1) to discharge or death of patient (AEC7) from the ICU were statistically analyzed using paired ‘t’ test for patients who recovered or those who died. The aim of this study was to identify whether the sequential estimation of AEC with a rising trend can be a prognostic factor of recovery in our Covid 19 patient in Khoula Hospital ICU at Oman as compared to those who died. Our results showed that the values of AEC1 was zero in 38 out of 43 patients with the mean of 0.0190. Comparisons were made between AEC1 with other readings (AEC2 to AEC7) and they demonstrated no definite trend that could be attributed to the changes in treatment modality in patients while in ICU.
