Background: Haematological markers such as absolute lymphopenia has been associated with severe COVID-19 infection. However, the described cohorts were generally unwell with a large proportion of patients requiring intensive care stay. It is uncertain if these markers apply to a population with less severe illness. We sought to describe the haematological profile of patients with mild disease with COVID-19 that were admitted to a single centre in Singapore. Methods: We examined 554 consecutive PCR positive SARS-COV-2 patients who were admitted to a single tertiary healthcare institution from Feb 2020 to April 2020 2020.

Results: Patients with pneumonia had higher neutrophil percentages (66.5±11.6 vs 55.2±12.6%, p
