Abstract: Coronavirus disease 2019 (COVID-19) has affected a broad demographics, eliciting a more significant effect on specific groups such as males, African Americans, and Hispanic minorities. Treatment of COVID-19 often requires antiviral drugs or monoclonal antibodies. However, immunotherapies such as mesenchymal stem cells and mesenchymal stem cells-derived exosomal vesicles should be evaluated as treatment options for COVID-19. Mesenchymal stem cell therapy offers regenerative, anti-inflammatory, and immunomodulatory properties that can speed up the recovery from COVID-19. Mesenchymal stem cell therapy can also benefit COVID-19 patients who suffer from strokes, as COVID-19 increases the risk of strokes due to increased cytokines and clotting factors. Most stroke cases that occur in COVID-19 patients are ischemic strokes. Therefore, with the help of mesenchymal stem cell therapy and mesenchymal stem cells-derived exosomes, COVID-19-induced stroke patients might benefit from dual-ended treatment. The objective of this review was to discuss COVID-19 and stroke incidence and the available treatment options.
