Professor Omid Dadras's research lab focuses on understanding the pathophysiological mechanisms underlying severe outcomes in aging populations during viral infections, particularly SARS-CoV-2. The lab investigates the interplay between viral load, host age, and disease severity, with an emphasis on identifying biological and clinical determinants of poor prognosis in older adults. Key research directions include viral transmission dynamics, age-related immune responses, and the development of targeted interventions to improve outcomes in elderly patients. The lab also explores the implications of these findings for public health strategies and clinical management protocols.

The results were inconclusive about the relationship between COVID-19 severity and viral load, as a similar number of studies either approved or opposed this hypothesis. However, the studies denote the direct relationship between older age and higher SARS-CoV-2 viral load, which is a known risk factor for COVID-19 mortality. The higher viral load in older patients may serve as a mechanism for any possible relationships between COVID-19 viral load and disease severity. There was a positive correl
Overall, a critical consideration is necessary for the care and management of COVID-19 in the aged population considering the drastic contrasts in manifestation and prognosis compared to other age groups. Mortality from COVID-19 is independently associated with the patient's age. Elderly patients with COVID-19 are more vulnerable to poor outcomes. Thus, strict preventive measures, timely diagnosis, and aggressive therapeutic/nontherapeutic care are of great importance to reduce acute respiratory
