Coronavirus (Covid-19): More Scary than Dangerous?
Assessing the impact of Coronavirus (Covid-19) on Total Deaths
- Problem :
- At the cusp of reported US Coronavirus deaths hitting the 100,000 mark (27 Mary 2020), it would be wise for us to step back a bit and review how dangerous this virus really is. We have a media environment with hidden agendas, conflicting accounts of Covid-19 death numbers, and varied cause of deaths (COD) attributions.
- What is the actual impact of Covid-19 on the total deaths numbers? Is the Coronavirus more scary than dangerous?
- Solution :
- One method is to analyse and compare the deaths due to All Causes over the same period of months, and contextualize over a number of years.
Data from US Center for Disease Control (CDC)
The country where the total deaths data over multiple years is most easily accessible is the US. The US CDC publishes this data over at the “Pneumonia and Influenza Mortality Surveillance from the National Center for Health Statistics Mortality Surveillance System” site (https://gis.cdc.gov/grasp/fluview/mortality.html)
At the time of this writing, Week 18 (starting 27 Apr 2020) is the latest week for 2020 where complete data is available. From this Database, the All Causes Deaths numbers can be viewed graphically thus:

Weekly All Causes Deaths (US CDC) |
Depicting Table 1 graphically, we can see a clear (almost linear) upward trend in overall All Causes Deaths in the US over the recent years. This has been trending even before the Coronavirus.

Conclusions
The historical peak of 71.5k deaths at week 15 indicates that Coronavirus did have an impact. Traditionally the peaks occur earlier in the season. The 71.5k number is indeed a strong spike.
However, when overall deaths numbers for the season are seen in a historical context, the excess deaths for the 2019-2020 season is not exceptionally high, and in fact follows the historically (rising) trend of deaths (with or without Coronavirus).
Perhaps, as this linked article suggests, Coronavirus has been more scary than dangerous.
Caveat – as this analysis stops at week 18, it is entirely possible that new data from subsequent weeks (when available) may point to a different assessment of the fatality counts and impact of Coronavirus to overall deaths.
