All data is downloaded and updated from Iowa’s COVID-19 in Iowa website at 10:30AM and 10:30PM each day.


Active Infections

The State of Iowa counts Iowans as “recovered” when they have displayed no fever for 3 consecutive days and have had a decrease in other symptoms. Recovered does not mean that all symptoms are gone nor is the person ready to return to life as usual. Many COVID-19 patients can experience post-viral illness for days to months after contracting the infection. The calculation for the above graph is:

Active Infections = Total Positives – (Total Recoveries + Total Deaths)

That means that there might well be more people actively infected in the state and in individual counties than is shown in the graph. On 6/29/2020 the State of Iowa recovered 5158 Iowans. This has been explain as a “data cleanup,” which means that Iowans might have recovered prior to that date but were not properly noted in the data. On 6/30/2020, the State of Iowa announced via an unannounced press conference that a positive is considered recovered if they have be deemed positive for 28 days and had neither been hospitalized nor able to be contacted.

Statewide 24-Hour Positivity

According to the World Health Organization, countries/states/counties with extensive testing should be at a positivity of 5% or lower. A high positivity rate means that testing is revealing predominantly symptomatic positives and might be missing asymptomatic/subclinical positives.

Influenza/Pneumonia Deaths vs. COVID-19 Deaths (2019-Present)

COVID-19 Deaths in Iowa (All Causes)

CDC Reported vs State of Iowa Reported
When scientists are presented with new information, we modify our hypotheses to reflect that new information. A few fellow data analysts looked at the nationwide data and it appears that all US states have two fields for COVID-19: one for underlying cause exclusively and another for multiple causes. It appears that underlying cause is a subset of multiple causes. I am still concerned that, even if we are interpreting the data from the CDC wrong, Iowa’s deaths are not being reported correctly or in a timely-enough fashion on the COVID-19 in Iowa website anyway. Individual counties are reporting deaths multiple days before the state reports those deaths. That lag time is painful for those who have lost their loved ones.
