Worth County

Population: 7381

All graphs and tables are calculated at 10:30 AM/PM from data downloaded from COVID-19 in Iowa.
I stream all data analysis and updating live on Twitch starting at 10:15 AM/PM everyday.

Active Infections

Graphed Infections Since 05/15/2020
These infections have been calculated from the State of Iowa’s official data. Actual levels of infection are considerably higher, based on positivity values in each county and statewide. The Director of the CDC, Dr Robert Redfield, has stated that viral prevalence is reasonably 10 times higher than what has been revealed through testing.
% Iowans Infected by Day
This percentage is based on the number of active infections out of all residents of Worth.

Snapshot Statistics

24-Hour Values
Cumulative Values
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. Positivity over a 12-hour period should return a similar positivity percentage, provided that enough testing is being done everyday.
Case Fatality Rate
Hospitalizations by Day
This data is sourced from COVID-19 in Iowa in the PDF available below the graphs and table on the first page. It is normally out-dated by at least 2-4 days and is only updated by the state a few days each week. Unfortunately, the data is not as complete as Iowans deserve on the county level.

County Positivity

24-Hour Positivity
County positivity percentages over any given 24-hour period will fluctuate wildly in most counties. This effect is smoothed out by doing an average positivity calculation to see what trend line appears.
14-Day Rolling Average Positivity
There is a large disparity between the 14-day rolling average positivity that I calculate and that of the State of Iowa. When a lab result is imported into the Iowa Disease Surveillance System (IDSS), it already contains the data of the sample collection. The system then adds the data the result is imported into IDSS.

The State of Iowa releases one set of data to the public based on the date the test was imported into IDSS. I calculate the 14-day rolling average positivity based on that dataset. It is a complete 14-day dataset based on the date imported into IDSS.

However, the State of Iowa calculates the 14-day positivity based on the date of sample collection – a variable that is not available to me or other everyday Iowans. Since sample results are reported to the State of Iowa 2 to 10 days after the sample is collected, the State of Iowa is calculating a 14-day positivity based on 10 to 12 days of data rather than 14 days of data. This artificially lowers the 14-day positivity when compared to the positivity that I calculate.

Iowa Department of Education Guidance

None to Minimal Community Transmission (0-5% 14-Day Rolling Average Positivity):
At this level, schools are asked to continue on-site learning following public health guidance, or hybrid learning as necessary based on parent preference and student quarantine.

Minimal to Moderate Community Transmission (6-14% 14-Day Rolling Average Positivity):
At this level, schools are asked to continue on-site learning following public health guidance, or hybrid learning as necessary based on parent preference and student quarantine, and limit some interactions. 
Iowa Department of Education Guidance

Substantial Controlled Community Transmission (15-20% 14-Day Rolling Average Positivity):
Schools are asked to follow hybrid learning plans as necessary based on parent preference and student quarantine. Schools that also have 10% absenteeism among students can request the Department of Education to transition to continuous remote learning for up to 14 days.

Substantial Uncontrolled Community Transmission (>20% 14-Day Rolling Average Positivity): 
Schools can request the Department of Education to transition to continuous remote learning for up to 14 days.
