Challenge 2: Hospitalization Rates for the Seasonal Flu v. COVID-19
Learning Targets:
- Differentiate between a pandemic and epidemic.
- Analyze and interpret epidemiological data.
- Perform calculations in order to accurately compare data.
- Identify and use credible sources to find data to support a conclusion.

One afternoon, June and her siblings, her brother Ruben and older sister Carla, are sitting around the family room of their home with the TV tuned in to a local channel. A preview for the evening news comes on and the newcaster asks in a serious, but dramatic voice, “Hospitalization rates for COVID-19 are on the rise, could the number of hospitalizations outnumber those for last year’s seasonal flu?”
“Wait a minute,” Ruben says, “I thought this pandemic is more serious than the seasonal flu. I didn’t realize that people are hospitalized with the flu so often.”
“Yeah,” June agrees, “I know lots of people who have had the flu and they miss a few days of school, but then they are fine.”
“Well, just like we are seeing with COVID-19, some people are more vulnerable than others and end up with more serious medical conditions from the flu,” Carla describes inserting her knowledge of public health.
“My friend Ray has a cousin who is a nurse at the hospital in New Haven and apparently, there have been a ton of hospitalizations for COVID-19 in the last few months and at times it’s been overwhelming,” June says.
“Yeah, it doesn’t seem like the seasonal flu overwhelms hospitals the way that COVID-19 has,” Ruben comments.
Investigate & Analyze
Part 1. Comparing hospitalizations from the seasonal flu and COVID-19
“Let’s look at the data and see what the numbers say,” Carla suggests. And she pulls up a few sources of data, two are compiled by the Centers of Disease Control and one by the NYTimes.
Seasonal Flu 2018-19 CDC:Use the websites to answer each question below about hospitalizations for the 2018-19 season of influenza and for COVID-19.
- Conclude:
- Which age group had the largest number of hospitalizations due to influenza in the 2018-19 season?
- Calculate and Conclude:
- Which age group had the largest hospitalization rate (per 100,000) during the entire 2018-19 flu season?
- Which age group had the largest hospitalization rate (per 100,000) during the entire 2018-19 flu season?
- Reflect and Discuss:
- If your answers to the above two questions are different, explain what could account for this difference.
- If your answers to the above two questions are different, explain what could account for this difference.
- Investigate:
- What was the percentage of patients hospitalized with COVID-19 for the week ending 09-Jan-2021 (the week with the greatest number of hospitalizations in the pandemic so far) who were 65+? How about the percentage of people who were 0-4?
- What was the percentage of patients hospitalized with COVID-19 for the week ending 09-Jan-2021 (the week with the greatest number of hospitalizations in the pandemic so far) who were 65+? How about the percentage of people who were 0-4?
- Compare:
- How do the percentages you found in part d compare to the percentages of people in the same age groups hospitalized with the seasonal flu in 2018-19?
- How do the percentages you found in part d compare to the percentages of people in the same age groups hospitalized with the seasonal flu in 2018-19?
- Discover:
- Using the NYTimes coronavirus data, find the chart under “US Trends” that illustrates the all time number of hospitalizations during the pandemic. Use this chart to find 7-day average hospitalizations on Jan. 9, 2020.
- Using the NYTimes coronavirus data, find the chart under “US Trends” that illustrates the all time number of hospitalizations during the pandemic. Use this chart to find 7-day average hospitalizations on Jan. 9, 2020.
- Compare:
- Compare the number you identified in part f to the total number of hospitalizations for the entire flu season of 2018-19.
- Compare the number you identified in part f to the total number of hospitalizations for the entire flu season of 2018-19.
Part 2 - Hospitalizations before and after wide-spread vaccination
CDC Hospitalization Data:
- Investigate:
- Using the graphic to search by jurisdiction, find current 7-day average for new hospital admissions for the week of Dec. 31, 2020 to Jan. 6, 2021 for the following jurisdictions:
- United States
- Connecticut
- Mississippi
- Using the graphic to search by jurisdiction, find current 7-day average for new hospital admissions for the week of Dec. 31, 2020 to Jan. 6, 2021 for the following jurisdictions:
- Compare:
- Again using the graphic, find current 7-day average for new hospital admissions for the week of Aug. 18, 2020 to Aug. 24, 2021 for the following jurisdictions:
- United States
- Connecticut
- Mississippi
- Again using the graphic, find current 7-day average for new hospital admissions for the week of Aug. 18, 2020 to Aug. 24, 2021 for the following jurisdictions:

Hints |
|
Are all ages affected equally? |
|
Estimate the number of hospitalizations due to COVID-19 over a month, several months, or year. |
|
How is the flu prevented? Also, are there treatments that exist for the flu? |
|
Where did they decrease or increase? |
|
Factor in the vaccination rates when comparing hospitalizations in different jurisdictions. |
