Cases and Hospitalizations

These charts show the 5-day moving average for both reported cases and hospitalizations.

Active Cases and Hospitalizations

How many people in Northern Virginia currently have COVID-19? We use the term “Active” to refer to cases from the past 14 days. The duration of illness or infection from COVID-19 is up to 14 days, for most people. For a given day, the “Active Cases” metric is the total number of reported cases for the past 14 days. This allows us to focus on the current spread of the disease in Northern Virginia, vice cases that have long since resolved. It can also give you a sense of the likelihood of interacting with an individual with COVID-19.

For example, there were 6861 active cases on November 22, 2020. This means in an area with a population of over 2.3 million, a total of 6861 people were positive for COVID-19 on that day. Of course, this does not account for people who have COVID-19 but have not been tested, including a potentially substantial number of asymptomatic individuals.

\(~\)

The active hospitalizations metric is similar in that it captures the total number of hospitalizations in the past 14 days for each day.

\(~\)

However, not all of the counties in Northern Virginia are the same size in population. This chart shows the number of cases in each county, per million in population. When compared to the previous chart, you see that while Fairfax County generally has the most new cases, other counties sometimes have higher case rates relative to population size.
