The graphics on this page are based on daily updates from the state released around 10 every morning. Dates indicate when information was reported. The column charts in the first visualization are most useful for evaluating trends. Since the results of many tests aren’t available immediately, numbers do not necessarily reflect the current level of spread of the virus. Feedback? Email coordinators@baltsun.com.

Day by day: Maryland COVID-19 cases, hospitalizations, deaths, testing volume and positivity rate

Note: On March 30, the Maryland Department of Health reported a decline in the cumulative number of hospitalizations, to 37,575 from 37,578. Officials say that this reflects a correction prompted by a hospital system’s update to its data.


Testing volume and positivity rate data in the above graphic are based on the dates test results were electronically reported to the state. The positivity rate is the seven-day average reported by the state. To calculate the average, the state calculates the rate for each day (positive tests reported that day ÷ total tests reported that day), then averages the rates of the most recent seven days.

Day by day: Maryland COVID-19 vaccinations

Maryland is in Phase 3 of its vaccination plan. All Marylanders 12 or older are eligible to be vaccinated. Eligibility for 12-to-17-year-olds is limited to sites administering the Pfizer vaccine, as that is currently the only one approved for their age group.


The equivalent* of 52.64% of Maryland’s population has been at least partially vaccinated. This comprises 2,970,424 who have received at least their first dose of the Pfizer or Moderna vaccines and 212,081 who have received the one-dose Johnson & Johnson vaccine.

*Out-of-state residents vaccinated in Maryland are counted in Maryland’s statistics.
