The planning scenarios are being used by mathematical modelers throughout the Federal government, it added. Meanwhile, the Case Fatality Rate (CFR) only includes confirmed cases. Data in the planning scenarios document may also be useful to hospital administrators in assessing resource needs, the agency said. The estimated IFR for people in their 70s is 11 times the rate for 50-to-69-year-olds, 270 times the rate for 20-to-49-year-olds, and 1,800 times the rate for people younger than 20. According to Worldometer's tally, the current death toll in the United States is about 210,000.
