November 30, 2022: COVID Weekly Data Update

Risks Associated with COVID Reinfection

A previous study from the VA Administration on the risks associated with reinfection has been published in final form in Nature (I previously discussed the preliminary results).  As shown below, the risk (HR, hazard ratio) of adverse outcomes increases as the number of reinfections increases. 

Title:  Cumulative risk and burden of sequelae in people with one, two, and three or more SARS-CoV-2 infections compared to noninfected controls.

Take home message:  do what you can to prevent being reinfected with COVID, or infecting others.

Influenza in South Dakota

Cases of influenza in South Dakota continue to rise.  More information can be found at https://doh.sd.gov/diseases/infectious/flu/surveillance.aspx

High numbers of COVID-19, influenza and respiratory syncytial virus (RSV) are likely to stress local hospitals.  You can help your healthcare systems and providers, as well as high-risk individuals, by getting the updated bivalent COVID booster and the flu vaccine for this year. 

South Dakota Mortality Data

The number of deaths for August has been posted on the SDDOH website and the following graph has been updated.  The number of deaths from January through August 2022 is 5,930.  The average number of deaths for similar months for 2010-2019 was 5,149.  The number of excess deaths, or the difference between the observed and the average, is 781. 

On the positive side, the death rate for August was close to the average death rate between 1960 and 2019 (below).

COVID-19 in China and Global Concern

Katelyn Jetelina, an epidemiologist, writes a weekly blog titled “Your Local Epidemiologist.” This week’s blog is an excellent discussion of what is happening in China.  It’s a short read but summarizes the situation nicely.  I recommend reading it. 

Updates:

Note regarding this week’s data:  Local, state, and national data for this week are likely to be under-reported due to the short work week as a result of the Thanksgiving holiday.
