COVID-19 Quick Stats

Quick Facts

Coronavirus disease 2019 (COVID-19) is the disease caused by the virus SARS-CoV-2

SARS-CoV-2 is closely related to the viruses that cause SARS and MERS, which have both caused severe outbreaks of respiratory disease.

Case Fatality Rate (CFR) for COVID-19 in the US seems relatively stable at 5.7%, Italy/Spain/France/UK at 10-15%.

  • Case fatality rate is the proportion of attributable number of deaths from a disease to reported (clinical) cases.

Infection Fatality Rate (IFR) for COVID-19 in the US is estimated to be between 0.5% and 1.0% globally (Meyerowitz-Katz, 2020 - Pre-Print).

  • Infection fatality rate (IFR) is the proportion of attributable number of deaths to all those infected (includes sub-clinical and asymptomatic cases) and is expected to be lower than CFR.
  • This number can be estimated during an epidemic/pandemic from antibody (by determining seroprevalence) studies.
  • SARS-CoV-2 has a very high asymptomatic rate that makes it difficult to estimate this number, meaning that estimates will vary widely between region and testing methodology.

Seroprevalence is the prevalence of individuals with antibodies to SARS-CoV-2 in a population, meaning the percent of individuals that have or have recently had the disease, regardless of disease status (asymptomatic, sub-clinical, or full-clinical presentation).

  • Current seroprevalence estimates range from 1.5% up to 30%, varying from region and testing methodology (Levesque and Maybury, 2020), meaning that a greater portion of any given population is infected with SARS-CoV-2 than will be identified from routine testing.
  • Widespread seroprevalence of SARS-CoV-2 antibodies is not currently known with scientific certainty in the US.

Mortality rate is the attributable rate of deaths due to a disease in a population (e.g., out of 100,000 people what is the risk of death for a particular disease).

  • This number is not typically estimated until after an epidemic/pandemic.
  • Mortality rate of COVID-19 is not currently known with scientific certainty in the US.

Featured Report, May 2020

Center for Infectious Disease Research and Policy (CIDRAP) at University of Minnesota

  • CIDRAP has been a great resource for me during the pandemic and I would consider it a very high-trust source.
  • Recently, they have created a new section named “COVID-19: The CIDRAP Viewpoint”, which is a summary report from experts in the field.
  • Their first issue of the report, “The future of the COVID-19 pandemic: lessons learned from pandemic influenza” (Apr 30, 2020) contains some very pertinent estimates on the progression of the COVID-19 pandemic.
  • Researchers at CIDRAP estimate that the pandemic will continue for up to 18-24 months, and experience one of several potential disease curve patterns, pictured here below.

  • Recommendations from the report:
  • 1. States, territories, and tribal health authorities should plan for the worst-case scenario (Scenario 2), including no vaccine availability or herd immunity.
  • 2. Government agencies and healthcare delivery organizations should develop strategies to ensure adequate protection for healthcare workers when disease incidence surges.
  • 3. Government officials should develop concrete plans, including triggers for reinstituting mitigation measures, for dealing with disease peaks when they occur.
  • 4. Risk communication messaging from government officials should incorporate the concept that this pandemic will not be over soon and that people need to be prepared for possible periodic resurgences of disease over the next 2 years.
