Fatal cases of COVID-19 deepen our understanding of the disease's progression

(Frontiers) Identifying risk factors underlying fatal COVID-19 cases is critical to understanding - and treating - the deadly disease. In Wuhan, China, researchers studied 18 patients who did not survive COVID-19, most of whom were men over the age of 65 with underlying conditions, and many of whom became co-infected with other respiratory viruses, bacteria, and mycoplasma over the course of the illness. The authors emphasized the need for early interventions and nutrition support.
