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%.
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).
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).
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).

Today's episode is a special feature episode of the Planetary News Radio. It is in times of great need that scientists and community members must join together to protect the community, whether that is at the national level, state level, city, or friends and family. As you all know, the coronavirus (COVID-19) has rapidly spread around the world, and we are seeing increasingly sweeping government responses to this outbreak, including quarantines, travel restrictions, and the bolstering of healthcare services. Listen to my status update on the pandemic here in Corvallis, Oregon, as well as a global perspective. For more coronavirus data analytics and updates, visit http://ncov.iiress.com.
