What Data Should You Be Following to Understand COVID-19 in North Carolina?
As we approach the holidays, it’s important for all of us to be able to fully assess our risk of contracting COVID-19. Right now, North Carolina is seeing a surge in new positive cases and COVID-related hospitalizations.
The last nine months have been hard on everyone. Thanksgiving is knocking on our doors and soon Christmas will be here too. When you’re preparing for the holidays be sure to double-down on some of the precautionary measures you’ve already been taking — wash your hands frequently, practice social distancing, and limit exposure to those outside of your immediate family.
The metrics we’ve been following in North Carolina are trending up. The seven-day average of new positive cases has been just over 7% and increasing to 7.5% for the past two days. The seven-day average of COVID-related deaths has trended up to the high 30s.
Even though we’ve seen some upticks in hospitalizations over the last few weeks, the seven-day average of inpatient hospital bed capacity is steady in the low-60% range. For ICU’s, that figure is in the mid-50% range.
We’ll continue to follow the data wherever they lead us. Having this data at our fingertips allows us to make the best decisions for ourselves and our families.
On a daily basis, we’re being flooded with information and data about new cases, hospitalizations, and deaths from COVID-19. We need to listen and watch the signals that data tells us while also tuning out the noise.
To do that, there are three key metrics to watch:
· The seven-day rolling average of the percentage of new positive COVID-19 tests
· The seven-day rolling average of daily death numbers
· The seven-day rolling average of hospital capacity
We’re committed to using clearly sourced data, no matter what story they tell us — good, bad, or ugly. We need to watch it all so you can make informed decisions about returning to school or visiting loved ones who are at a higher risk for contracting COVID-19.
The graphs below help cut through the noise of the daily headlines talking about “records” or “increased cases.” We need to know what the state is facing without the noise of social media. Just the facts.
Seven-day rolling average of the percentage of new positive COVID-19 tests
Why is this important? This number gives us a signal of how the virus is spreading in North Carolina. It’s a clear way for us to understand the trends of positive cases in the state while cutting through the headlines about increased testing.
NOTE: On Aug. 12, NCDHHS announced that 221,444 tests were mistakenly added to the total of North Carolina’s tests. The tests did not impact the total number of positive tests but did impact the cumulative total of tests conducted. After doing an analysis of the corrected data and what had previously been reported, the 7-day rolling average did not shift substantially. That is one of the reasons why the 7-day rolling average is such an important metric. It allows us to see beyond any mistakes in the data.
Seven-day rolling average of daily death numbers
Why is this important? Watching this number gives us a sense of just how lethal the virus strain is and whether our efforts are helping or hurting. This, at times, can be a lagging indicator as deaths take time to be reported and investigated. According to DHHS, death data for the last two weeks may not be reported yet, which is data for that time period can fluctuate.
Seven-day rolling average of hospital capacity
Why is this important? Watching hospital capacity gives us a look at how serious cases are and if our hospitals are going to be overtaxed. One of the reasons Gov. Cooper shut down the state earlier this year was because he and Secretary Cohen were concerned that COVID-19 would overtake our hospitals. The concern was so great that eventually they put up additional triage spaces and make-shift hospitals to increase capacity. We never maxed out the hospitals. We know the most serious cases of COVID-19 end up in the hospital. But, capacity doesn’t capture only COVID cases, capacity is for ALL hospitalizations, including COVID patients.
This data will continue to change as the pandemic continues. That means we’ll continue to update these stats as we go along and add additional metrics we think are important. Please check back here a couple of times a week to see where North Carolina stands. If you have other key indicators that you’re watching, please share and let us know.
