I also added this column: During the 2017-2018 flu season the the % of deaths attributed to pneumonia and influenza (P&I) was at or above the epidemic threshold for 16 consecutive weeks, and exceeded 10.0% for four consecutive weeks, with older Americans dying at a rate of 169 Americans a day, or seven people per hour.

For this 2019-20 season, the CDC reports (March 28) that deaths due to P&I was 7.4%, which is above the epidemic threshold of 7.3%. The increase is due to an increase in pneumonia deaths rather than influenza deaths and may be associated with COVID-19.

However, the CDC reported that the flu rate is low even though the percentage of pneumonia and influenza is above the epidemic threshold of 7.0% for week 15. And here it listed 52,285 deaths for Week 13 and 49,292 deaths for Week 14 as of 4-18) ) for Influenza Deaths and Pneumonia Deaths combined. And note that some of the latter can be assigned to Covid.

[Notes * P+I deaths at or above epidemic threshold for 16 consecutive weeks. **as should be assumed in other cases, death rates include those due to complications accompanying the flu.

We have the CDC morality rates for the flu per state for 2017-18 (13 states above 17 per 100,000 total population) and for Covid here (only 8 states above 17 per 100,000 people, as of April 24). And according to estimates, between 61,000 to 80,000 Americans died during the 2017-2018 season, the latter being the highest death toll in 40 years. During that 2017-2018 season, the percentage of deaths attributed to pneumonia and influenza (P&I) was at or above the epidemic threshold for 16 consecutive weeks. Nationally, mortality attributed to P&I exceeded 10.0% for four consecutive weeks, peaking at 10.8% during the week ending January 20, 2018, (https://www.cdc.gov/flu/about/season/flu-season-2017-2018.htm) with older Americans dying at a rate of 169 Americans a day, or seven people per hour. (https://www.aarp.org/health/conditions-treatments/info-2018/older-flu-deaths-rising.html

It is estimated that about 80% of those infected with Covid-19 experience a mild case [WHO said the like] – about as serious as a regular cold – and recover without needing any special treatment. Meanwhile a study in Iceland reports that as of April 11, the country has “tested 10% of its population for coronavirus - a figure far higher than anywhere else in the world -” and that “about half of its citizenry at any given time who have coronavirus but don't know it, will be asymptomatic” (show no symptoms), which is “a large percentage many experts studying the virus have suspected, but have had little firm data to corroborate.”

Another report is that those who are most vulnerable to death from Covid-19 are the aged with certain other heath conditions, thus 80 percent of US coronavirus deaths are people 65 and older. Then again, America murders over 2,000 of the most vulnerable souls a day (2017: https://www.guttmacher.org/fact-sheet/induced-abortion-united-states), while (for perspective) about 90 people die each day in the US from crashes, which are among the over 7,000 Americans who die every day in the US from a wide range of causes. (https://www.weisspaarz.com/leading-causes-death-by-state/)

Other infectious diseases include: Severe acute respiratory syndrome, or SARS, and the mortality rate for SARS, that killed nearly 800 people, is estimated at 1 % by the C C, and with a R rating of 5.

MERS, which stands for Middle East re respiratory syn drone, had a mortality rate of 5% and a R rating of 2].

Measles: Mortality rate: unclear; R rating: 12 to 18

Ebola Mortality rate: exceeds 50% R rating: about 2
