In an outbreak of an infectious disease it is important to not only study the number of Cases and Deaths, but also the growth rate at which the number of deaths is increasing (worldometers).

Covid 19 study cases recently in the United states estimated a mortality rate of 10% to 27% for those ages 85 and over, 3% to 11% for those ages 65 to 84, 1% to 3% for those ages 55 to 64 and less than 1% for those ages 20 to 54.

Age Fatality Rates:

Death Rate = (number of deaths / number of cases)

AGE DEATH RATE confirmed cases DEATH RATE all cases
80+ years old 21.9% 14.8%
70-79 years old 8%
60-69 years old 3.6%
50-59 years old 1.3%
40-49 years old 0.4%
30-39 years old 0.2%
20-29 years old 0.2%
10-19 years old 0.2%
0-9 years old 0.002%
  • Critical cases: respiratory failure, septic shock, and/or multiple organ dysfunction/failure.
  • Severe cases: dyspnea, respiratory rate ≥30/min, oxygen sats ≤93%, PaO2/FiO2 ratio <300, lung infiltrates >50% within 24–48 hrs.
