 Summary of weekly data for the Lancaster area. 

This image shows recent stats for the Charleston area: 30.2 cases per day per 100,000 population for a 7-day average; test positivity for a 7-day average is 14.5 percent; percentage of total population vaccinated at two doses is 48 percent; percentage of total population boosted at 3 doses is 20 percent; percent of hospital beds being used for COVID-19 care is 7.3 percent; weekly COVID-19 hospital admissions per 100,000 population is 8.

The number of weekly COVID-19 infections officially reported is vastly under-counted due to home testing.

It is estimated that the number of actual COVID-19 cases is 6 to 10 times the number officially reported.

Based on these estimates, last week (January 22nd through January 28th) in the Lancaster area:

  • About 1 percent of the population were infected with COVID-19
  • 996 to 1,659 people were infected with COVID-19
  • 1 out of every 78 to 131 people were infected with COVID-19

Trend in cases from March through current month in Lancaster area.

What does the graph above tell us?

  • We recently had a surge of COVID-19 cases which began in the middle of May. Current data suggests that the surge is subsiding.
  • Beginning in early August the number of officially recorded COVID-19 infections peaked at 49 cases per day for every 100,000 people and has begun to slowly decline.
  • As of last week, we had 18.2 cases per day per 100,000 people. Since most people now test for COVID-19 with home test kits only about 10 to 17 percent of infections are officially recorded.
    • Adjusting for under-counting due to home testing, it is likely that the actual number of infections per 100,000 people per day is between 109 and 182. Those numbers are equal to 1 percent of the population infected every week.

      Final Version of long covid summary.

This graph shows that the 7-day average of COVID-19 cases in the Lancaster area is medium.

What does the graph above tell us?

  • This graphic shows the trends in the daily number of COVID-19 infections since the beginning of the pandemic for our area.
  • There have been 5 distinct surges. We have had a surge in both the summer and the winter each year.
  • The most recent surge was one of the longest we have experienced to date.
  • Bear in mind that the recent surge was different from past surges in several important ways:
    • In the recent surge there was significant under-counting of cases due to home testing for COVID-19.
    • Mitigation strategies such as mask use and distancing were much lower than in past surges.
    • The current predominant COVID-19 variant (BA.5) is the most effective variant yet at infecting people who are vaccinated, and reinfecting people who got COVID-19 in the past.
    • We now have access to medications that can reduce the severity of illness from COVID-19.
    • The death rate from COVID-19 is now much lower, due largely to immunity from vaccinations and prior infections. Regardless, there are now 580 people dying a day from COVID-19 in the United States, equivalent to 211,700 people a year.
