Covid-19 Cases, Hospitalizations and Deaths Compared
Confirmed COVID-19 cases, deaths, hospital admissions, and patients in ICU per million people in the United States, United Kingdom, Australia and South Africa as of September 20, 2022. Note the Omicron variant wave began first in South Africa,then spread to the UK, then other countries including the US and Australia.

Covid-19 Level of Community Transmission in the US
Covid-19 US Level of Community Transmission

< 200 cases

New COVID-19 admissions per 100,000 population (7-day total)2

< 10.0



Percent of staffed inpatient beds in use by COVID-19 patients (7-day average)3

< 10.0%



≥200 cases

New COVID-19 admissions per 100,000 population (7-day total)


< 10.0


Percent of staffed inpatient beds in use by COVID-19 patients (7-day average)


< 10.0%


The COVID-19 Community Level is determined by the higher of the new admissions and inpatient beds metrics, based on the current level of new cases per 100,000 population in the past 7 days.
1Number of new cases in the county in the past 7 days divided by the population in the county (or other administrative level) multiplied by 100,000.
2Total number of new admissions of patients with confirmed COVID-19 in the past 7 days divided by the total population in the Health Service Area, multiplied by 100,000.
3Percentage of staffed inpatient beds in use by patients with confirmed COVID-19 within the entire Health Service Area (7-day average).
