vacovdata

Data frame with 24 columns

date: Date of the report
positive: Cumulative number of positive tests.
negative: Cumulative number of negative tests.
pending: Number of pending tests. This data is very spotty.
hospitalizedCurrently: Number of COVID-19 patients in hospitals.
hospitalizedCumulative: Cumulative number of COVID-19 hospitalizations. This column seems to have a lot of missing data.
inIcuCurrently: Current number of COVID-19 patients in ICU.
inIcUCumulative: Cumulative number of COVID-19 ICU cases.
onVentilatorCurrently: Number of COVID-19 cases currently reported as being on a Ventilator.
onVentilatorCumulative: Cumulative number of COVID-19 ventilator cases.
recovered: Number of COVID-19 cases reported as recovered. It isn't exactly clear who is counted in this total, hospitalized cases or all confirmed cases.
hash: A hash of the data (probably SHA-1, but this isn't specified). It isn't clear whether this is computed on the single row of data, or on all of the data cumulative to that point. Also, since we drop some columns that aren't useful to us, we can't recompute this hash; it's here as a key allowing us to backtrack where a row of data originally came from, if needed.
dateChecked: Date and time that the COVID Tracking Project updated their data from VDH.
death: Cumulative number of COVID-19 deaths.
deathIncrease: Number of new deaths for the day.
totalTestResults: Cumulative number of test results.
totalTestResultsIncrease: Total number of new tests performed that day.
negativeIncrease: Number of new negative test results.
positiveIncrease: Number of new positive test results. This is also the number of new confirmed cases.
fpos: Fraction of positive tests on this day.
fposCumulative: Cumulative fraction of positive tests.
vapop: Total population. This is presumed constant over the time period being considered here.
ftest: Fraction of the total population tested on this day.
ftestCuulative: Total fraction of population tested.

Starting on 05/02, total test and negative test counts are reported based on the unique tests performed, rather than on the raw test counts. In the previous two versions this caused cumulative counts to drop on that date. This patch makes a correction based on the discrepancy on May 2nd.

The practical upshot of this change is that the cumulative counts of negative tests and total tests are based on all tests performed up to May 2nd, plus unique tests performed after that. This means the definition of those quantities is a bit inconsistent over time, but at least we don't get a negative test count on May 2nd.
