According to CDC data, Native Americans have 5.3 times higher rates of hospitalization, 1.4 times higher rates of death...

Mientras desarrollamos nuestro primer modelo, lamentablemente no...

Infection Rate: Explained


The Infection Rate, or “R(t),” is the number of people one infected person goes on to infect in a specific area, over a specific time. The areas we look at are county and state. The period of time we look at is while a person is contagious (able to spread COVID). In the picture to the right, R(t) is 3. If the R(t) is 3, one person will most likely infect three other people, and those three people...

ICU Headroom Used: Explained
