The important issue isn't whether this corona virus is that deadly. The issue becomes important when it drastically affects the health care systems due to surge. There has always been a delicate balance between the number of sick patients and the number of health care workers/beds/meds/equipment to treat. Any disturbance in the force that can prevent truly sick people with other illnesses from obtaining the healthcare they need due to overcrowding, lack of meds, ventilators, and health care workers to treat due to a rapidly spreading virus such as SARS, MERS, or whatever this thing is finally referred to as is really the main factor that one needs to be concerned about.
