Data Definitions and Sources:

Charles County residents with a positive result, meaning confirmation of SARS-CoV-2 infection from a PCR-RNA laboratory test, are included in the total case count. Laboratories report results electronically to the health department through the National Electronic Data Surveillance System.

The total case count represents all confirmed cases of SARS-CoV-2 among Charles County residents since the pandemic began. The number of new cases reported to the health department in the last 24 hours and in the last week are also presented to help describe the current spread within the community.

This is the percentage of people who have tested positive over the past 7 days who are not fully vaccinated. Not fully vaccinated also includes those who are partially vaccinated at the time of a positive result.

Positivity Rate is the total daily number of virus tests conducted in the county and of those tests, how many were positive each day. Since we report weekly, we share the average percentage of tests that were positive over the last 7 days.

Data Source: Maryland Department of Health COVID-19 Data Dashboard

Case Rate is the number of cases per 100,000 residents. Since we report data weekly, we share the 7-day moving average Case Rate.

Using the population size in the calculation helps us more easily compare larger and smaller counties. A larger county would be expected to have more total cases because of the larger population, but expressing the rate per 100,000 residents enables a more equal analysis.

A county’s Level of Community Transmission is based on two metrics: the Case Rate and the Positivity Rate, both measured over the last seven days. The basic idea is that this shows how much virus is spreading around us and is an important determinant of how much risk you’re in.

The CDC recommends that all people, including those who are vaccinated, wear masks indoors if a county has “Substantial” or “High” rates of community transmission.

There are four levels in the CDC measure: Low, Moderate, Substantial, and High.

This is the increase (or decrease) from the previous week in the number of Charles County residents who are currently hospitalized due to complications from COVID-19. Residents may have been hospitalized at any hospital (non-psychiatric acute care facilities) due to COVID-19 in Maryland, D.C., Virginia, and other states. Data is not reflective of current patient status. Data excludes Emergency Department visits and federal hospital/care facilities e.g., Veterans Administration, NIH, etc.

This is the total number of Charles County residents who have died from COVID-19 since the start of the pandemic. COVID-19 deaths are counted when the disease is listed on the death certificate. When someone dies in a health care facility, the task of determining the cause usually goes to a physician who oversaw the person’s care or the person’s primary care doctor. Coroners and medical examiners make the determination in various other instances, including deaths that occur at home.

Part I and II of a death certificate ask what caused a death and what other factors contributed to it. If COVID-19 appears among the causes and contributors, CDC guidance counts that as a COVID-19-related death.

Part I asks for the “immediate cause” of death, followed by any “conditions that led to the immediate cause,” the CDC explains in guidelines for certifying COVID-19 fatalities. For example: In some COVID-19 cases, the immediate cause is an affliction that arose from the disease, such as pneumonia, while COVID-19 gets listed under that as an underlying condition that led to death. In other words, COVID-19 caused the pneumonia.

Part II asks for conditions that did not set off medical events that led to death but contributed in some other way. Here, COVID-19 appears as sort of an accomplice to a fatality that was probably going to occur from something else (such as a preexisting, terminal disease), but was accelerated by the person having contracted COVID-19.

If COVID-19 is listed on the death certificate, the Maryland Department of Health reviews the National Electronic Disease Surveillance System to determine if the individual has a positive laboratory result for SARS-CoV-2. If a positive result is found, the death is classified as “confirmed.” If a positive laboratory cannot be found but the death is epidemiologically linked to a COVID-19 outbreak and the clinical presentation was indicative of COVID-19 infection, then the death is listed as “probable.”

This data reflects the number of Charles County residents that have received first or second doses of a series, including Pfizer and Moderna and single dose vaccines, such as Janssen. The actual total may be higher than reported due to delays in the electronic reporting system.

Because this data source is specific to individual test results, just like other data originating from CRISP, access is highly controlled for privacy reasons and there is no public access to this data source.

This data reflects the number of individuals that have received the first and second doses of a series, including Pfizer and Moderna, and single dose vaccines, such as Janssen that were administered by the Charles County Department of Health. This data includes both Charles County residents and residents from other jurisdictions that are eligible for vaccination due to occupation. The actual total may be higher than reported due to delays in the electronic reporting system.

The data shows the percentage of people in the age category who are fully vaccinated. This means they have completed 2 shots of Moderna or Pfizer or 1 shot of Johnson & Johnson.

The number of doses for the 5-11 age group is given since authorization for this population was only recently approved by the FDA. At this time, no children aged 5-11 have had time to complete the full series and to be classified as fully vaccinated. Once that changes, we will change the statistic to show a percentage like the other age groups displayed.

Because this data briefing may include data on small sample sizes, it is not made publicly available for privacy reasons. The data contained in the report comes directly from the Maryland Department of Health, using the statewide combined reporting system, known as the Chesapeake Regional Information System for Our Patients (CRISP) Health Information Exchange.

Viruses constantly change through mutation. As expected, multiple variants of COVID-19 have been documented in the United States and globally throughout this pandemic.

We report on Variants of Concern identified in Charles County. These are variants for which there is evidence of an increase in transmissibility, more severe disease (e.g., increased hospitalizations or deaths), significant reduction in neutralization by antibodies generated during previous infection or vaccination, reduced effectiveness of treatments or vaccines, or diagnostic detection failures.
