August 27: University of Washington COVID-19 Projections

This is a work in Progress


Home

The projections from August 6 and August 21,are  projects through December 1, 2020.*  The other four projections are through November 1, 2020,  Georgia  has the highest projected death rate 2708 per million.  Projections rose by major proportions for Massachusetts, Arizona, District of Columbia, California, Illinois, South Carolina, Pennsylvania, Iowa, and North Dakota.  Decreases for Missouri, Kansas, Virginia and Wisconsin.

The August 21 projections are available from:  https://covid19.healthdata.org/united-states-of-america

DEATHS

How many overall deaths will there be?

Our model is updated to account for new data and information, and the estimates may change as a result. For the latest estimate, visit our COVID-19 projections tool.


Why do your results show a wide range in the forecast for deaths?

Larger uncertainty intervals – or the range within which estimated deaths are likely to fall – can occur because of limited data availability, small studies, and conflicting data. A smaller range generally reflects extensive data availability, large studies, and data that are consistent across sources.


Why did the estimates for my location change?

To learn more, please visit our update page.


Why is the peak for daily deaths still forecast in the future when it looks like it has already occurred in my location?

The date of peak daily deaths depends on the model’s projections. If the model projects that the number of daily deaths will continue to rise, then the peak will be projected for a future date. It is important to note that the data on daily deaths may fluctuate dramatically due to irregularities in reporting. Health care workers are extremely busy caring for COVID-19 patients, so they may fall behind on reporting deaths. Once health care workers catch up on their reporting, however, it may appear as though there has been a spike in daily deaths.


Why are the “observed deaths” shown in your results for my location different from what is shown on the government’s official page?

For deaths, we primarily use the COVID-19 death data aggregated by the Johns Hopkins University (JHU) data repository (see "Where does IHME obtain its data?"). The JHU repository uses Coordinated Universal Time (UTC), which means new days start at 8 p.m. Eastern time. The JHU counts may differ slightly from local government data as a result of these timing differences. Also, the JHU repository is not necessarily synchronized to the update schedule of every location, so there may be a short lag that is reflected in a difference between our recorded daily deaths in a given location and those ultimately reported on government websites. Although this will be corrected when we update our analysis, in some cases, these differences may persist for several days.

Yet another reason why observed deaths may differ from numbers reported by governments is due to data processing. To address irregularities in the daily death data, we average data from the last three days to create a smooth version. To see the death data exactly as it is reported, 1) click the “Chart settings” icon in the upper right corner of the chart, and 2) turn off “Smoothed data.”



There are reports of deaths being under-reported in places. How does this impact your forecast?

We are learning that not all deaths due to COVID-19 that occur at home or in nursing homes have been attributed to COVID-19. As awareness increases, the number of reported deaths is growing, with some locations now reporting presumptive COVID-19 deaths. Another challenge is that COVID-19 death data fluctuate substantially each day, with some locations reporting more deaths on Tuesdays than on Sundays and Mondays. We believe this variation is due to data reporting practices instead of actual death patterns. To mitigate the impact of inconsistent reporting on our forecasts, our published predictions are based on averaging multiple iterations of projections. As new data emerges, we incorporate it into our model, and our projections will shift up or down in response to the data. To learn more, see our estimation updates.

For Ecuador and Peru in particular, the number of reported deaths due to COVID-19 appears to be improbably low. Instead of using reported COVID-19 deaths for these countries, we are approximating deaths from COVID-19. To approximate COVID-19 deaths, we used the number of excess deaths occurring in Ecuador and Peru during the COVID-19 pandemic and observations from other countries where we had weekly reports of total deaths and high-quality data on COVID-19 deaths.
