Since a number of those who read these pages are 60 or older, and those 60 and older have been consistently reported to be at greater risk of dangerous Coronavirus-related complications and death than the younger population, I sought to discover currently-indicated mortality rates for those over 60. The first citation below links to a piece indicating that the risk of dying for the more senior infected by the virus roughly doubles by decade: for those aged 60 – 69 it is 3.6%, for patients aged 70 to 79 years it is 8%, and for patients above 80 years of age it is 14.8%.
[NOTE: The data related to the septuagenarians and octogenarians underlying the first link is apparently derived from a Chinese study based on 72,000 case records that I found cited on other sites (no links to those attached)]. [SECOND NOTE: Since the information underlying the first link is dated in late February, I’ve searched for more recent data; the second link below is to a MarketWatch story updated as of this morning (March 9), which still appears to rely on the same Chinese study for mortality rates among those 70 and older.] [THIRD NOTE: It is seemingly arguable that the virus is accelerating much more quickly than the data.]
We have seen indications that the disease can be particularly dangerous for adults with “underlying health conditions.” I have seen two sites that indicated that about 60% of U.S. adults have at least one affliction that would be considered “an underlying health condition.”
Below are links to four sites addressing different aspects of the challenge. Although I obviously lack the knowledge or resources to verify their accuracy, I found them informative.
