Myasthenic crisis in the setting of Coronavirus Disease 2019 (COVID-19).

• A patient with Myasthenia Gravis (MG) on immunosuppressive therapy with underlying respiratory compromise may be more susceptible to infection with COVID-19 or severe manifestations of the virus. • It is theorized that patients with MG may be more vulnerable to bacterial and viral infections, due to respiratory muscle weakness and use of immunosuppressive medications. • It is critical for practitioners to be prepared for severe respiratory compromise in patients with MG and concomitant COVID-19 superinfection.
