JEFFERSON CITY, Mo. – The state health department continues tracking the number of breakthrough COVID-19 cases across Missouri (fully vaccinated individuals who contract the virus). But how many vaccinated people have tested positive for the virus? Just over 1 in 50.
According to the Missouri Department of Health and Senior Services (DHSS), the state has recorded 782,935 cumulative cases of SARS-CoV-2—an increase of 1,400 positive cases (PCR testing only)—and 12,843 total deaths as of Monday, Dec. 20. That’s a case fatality rate of 1.64%.
It’s important to keep in mind that not all cases and deaths recorded occurred in the last 24 hours.
The state has administered 142,036 doses—including booster shots—of the vaccine in the last 7 days (this metric is subject to a delay, meaning the last three days are not factored in). The highest vaccination rates are among people over 65.
State health officials report 60.0% of the total population has received at least one dose of the vaccine. Approximately 71.1% of all adults 18 years of age and older have initiated the process.
Vaccination is the safest way to achieve herd immunity. Herd immunity for COVID-19 requires 80% to 90% of the population to have immunity, either by vaccination or recovery from the virus.
Just 2.24% of 3.26 million fully vaccinated Missourians have tested positive for COVID. And only 778 people (or 0.02%) of fully vaccinated people have died from the virus.
The first doses were administered in Missouri on Dec. 13, 2020.
The city of Joplin has vaccinated 60% of its population. St. Louis City, Kansas City, and Independence, as well as the counties of St. Louis, St. Charles, Boone, Atchison, and Jackson, have at least 50% of their population fully vaccinated. Thirty-seven other jurisdictions in the state are at least 40% fully vaccinated: Cole, Franklin, Greene, Cape Girardeau, Jefferson, Nodaway, Cass, Ste. Genevieve, Carroll, Andrew, Callaway, Gasconade, Christian, Benton, Adair, Clinton, Dade, Livingston, Ray, Lafayette, Montgomery, Shelby, Osage, Henry, Clay, Camden, Warren, Howard, Cooper, Phelps, Stone, St. Francois, Holt, Platte, Chariton, Pettis, and Sullivan counties.

The Bureau of Vital Records at DHSS performs a weekly linkage between deaths to the state and death certificates to improve quality and ensure all decedents that died of COVID-19 are reflected in the systems. As a result, the state’s death toll will see a sharp increase from time to time. Again, that does not mean a large number of deaths happened in one day; instead, it is a single-day reported increase.
At the state level, DHSS is not tracking probable or pending COVID deaths. Those numbers are not added to the state’s death count until confirmed in the disease surveillance system either by the county or through analysis of death certificates.
The 7-day rolling average for cases in Missouri sits at 2,203; yesterday, it was 2,159. Exactly one month ago, the state rolling average was 1,996.
The 10 days with the most reported cases occurred between Oct. 10, 2020, and Nov. 29, 2021.
Approximately 50.1% of all reported cases are for individuals 39 years of age and younger. The state has further broken down the age groups into smaller units. The 18 to 24 age group has 93,542 recorded cases, while 25 to 29-year-olds have 66,081 cases.
People 80 years of age and older account for approximately 41.6% of all recorded deaths in the state.

Missouri has administered 8,218,398 PCR tests for COVID-19 over the entirety of the pandemic and as of Dec. 19, 17.3% of those tests have come back positive. People who have received multiple PCR tests are not counted twice, according to the state health department.
According to the state health department’s COVID-19 Dashboard, “A PCR test looks for the viral RNA in the nose, throat, or other areas in the respiratory tract to determine if there is an active infection with SARS-CoV-2, the virus that causes COVID-19. A positive PCR test means that the person has an active COVID-19 infection.”
The Missouri COVID Dashboard no longer includes the deduplicated method of testing when compiling the 7-day moving average of positive tests. The state is now only using the non-deduplicated method, which is the CDC’s preferred method. That number is calculated using the number of tests taken over the period since many people take multiple tests. Under this way of tabulating things, Missouri has a 13.2% positivity rate as of Dec. 17. Health officials exclude the most recent three days to ensure data accuracy when calculating the moving average.
The 7-day positivity rate was 4.5% on June 1, 10.2% on July 1, 15.0% on Aug. 1, and 13.2% on Dec. 1.
As of Dec. 17, Missouri is reporting 1,914 COVID hospitalizations and a rolling 7-day average of 1,965. The remaining inpatient hospital bed capacity sits at 16% statewide. The state’s public health care metrics lag behind by three days due to reporting delays, especially on weekends. Keep in mind that the state counts all beds available and not just beds that are staffed by medical personnel.
On July 6, the 7-day rolling average for hospitalizations eclipsed the 1,000-person milestone for the first time in four months, with 1,013 patients. The 7-day average for hospitalizations had previously been over 1,000 from Sept. 16, 2020, to March 5, 2021.
On Aug. 5, the average eclipsed 2,000 patients for the first time in more than seven months. It was previously over 2,000 from Nov. 9, 2020, to Jan. 27, 2021.
The 2021 low point on the hospitalization average in Missouri was 655 on May 29.
Across Missouri, 481 COVID patients are in ICU beds, leaving the state’s remaining intensive care capacity at 16%.

As of Dec. 19, the CDC identified 50,636,126 cases of COVID-19 and 802,969 deaths across all 50 states and 9 U.S.-affiliated districts, jurisdictions, and affiliated territories, for a national case-fatality rate of 1.59%.
How do COVID deaths compare to other illnesses, like the flu or even the H1N1 pandemics of 1918 and 2009? It’s a common question.
According to the Centers for Disease Control and Prevention (CDC), preliminary data on the 2018-2019 influenza season in the United States shows an estimated 35,520,883 cases and 34,157 deaths; that would mean a case-fatality rate of 0.09 percent. Case-fatality rates on previous seasons are as follows: 0.136 percent (2017-2018), 0.131 percent (2016-2017), 0.096 percent (2015-2016), and 0.17 percent (2014-2015).
The 1918 H1N1 epidemic, commonly referred to as the “Spanish Flu,” is estimated to have infected 29.4 million Americans and claimed 675,000 lives as a result; a case-fatality rate of 2.3 percent. The Spanish Flu claimed greater numbers of young people than typically expected from other influenzas.
Beginning in January 2009, another H1N1 virus—known as the “swine flu”—spread around the globe and was first detected in the US in April of that year. The CDC identified an estimated 60.8 million cases and 12,469 deaths; a 0.021 percent case-fatality rate.
