Release Log

• v1.11.1 Friday, December 11, 2020

  Signal Changes

  • Removed “COVID Symptom Searches on Google” signal.
  • Replaced “COVID-Related Doctor Visits” with new signal from Change Healthcare. For more details see: chng:smoothed_outpatient_cli

• v1.11.0 Wednesday, December 2, 2020

  This release changes COVIDcast from a complete site to an embedded component, primarily to the www-main repository, which serves the Delphi homepage. This means that instead of having both covidcast.cmu.edu and delphi.cmu.edu separately, we will now have delphi.cmu.edu and covidcast will live at delphi.cmu.edu/covidcast.

  The are only minor changes to the COVIDcast visualization itself, which was why this is marked as 1.11.0 instead of 2.0.

  Signal Changes

  • “COVID Searches on Google” is now “COVID Symptom Searches on Google”. For more details see: google-symptoms sum_anosmia_ageusia_smoothed_search signal.
  • New “Bar Visits” signal from Safegraph. For more details see: safegraph bars_visit_num and bars_visit_prop.
  • New “Restaurant Visits” signal from Safegraph. For more details see: safegraph restaurants_visit_num and restaurants_visit_prop
  • “Away from home” signals replaced by smoothed versions to remove the weekend effect. For more details see: safegraph full_time_work_prop_7dav and part_time_work_prop_7dav

  • Spike maps have been added as an option to visualize case and death indicators, along with bubble maps.
  • The design of the COVIDcast home page has been improved to include navigation to other parts of the site and to other Delphi web pages.

• v1.5 Wednesday, July 8, 2020

  • The map layout has been redesigned to prevent the controls from obscuring the map.
  • Updated maps: The cases and deaths maps now use data from both Johns Hopkins University and USAFacts. Data from Johns Hopkins University is used for Puerto Rico, while USAFacts is used everywhere else.
  • Numerous minor bug fixes.

• v1.4.1 Wednesday, July 1, 2020

  • New map: The “Hospital Admissions” map indicates the proportion of daily hospital admissions with COVID-related diagnoses, based on data from health system partners.
  • Minor bug and layout fixes.

• v1.4 Wednesday, June 24, 2020

  • Map controls have been revised to more easily select indicators and geographic areas.
  • A new search bar makes it possible to quickly find any county or city of interest.
  • The color scale for increasing and decreasing 7-day trends has been updated to more clearly highlight trends.
  • New maps: The “Away from home” maps use mobile device location data from SafeGraph to estimate the proportion of people spending time outside their homes each day, for either 3-6 hours or more than 6 hours.
  • Map color scales on the cases and deaths maps are now logarithmic, making it easier to see differences among regions with both low rates and high rates.
  • Cases and deaths maps are now based on 7-day averages, rather than reporting figures for a single day.

• v1.3 Wednesday, June 10, 2020

  • The COVIDcast map now includes Puerto Rico. Not all data sources are available for Puerto Rico, but data will be displayed when available.
  • The “Combined” signal now includes standard error bands when viewing the time series plot for a specific geographical area, representing the estimated uncertainty in this signal. This uncertainty comes because the signal is a combination of the other signals which are based on survey estimates or other estimates with margins of error.
  • Tooltips for the official Cases and Deaths signals have been updated to contain the population, raw count, and count per 100,000 people, to help distinguish sparsely-populated areas with one or two cases from dense urban areas with more total cases but an apparently lower rate per 100,000 people.
  • Fixed a bug that inflated the color value for per capita Cases and Deaths relative to the legend.
  • Other small bug fixes and improvements in the COVIDcast map.

• v1.2.1 Thursday, May 28, 2020

  • The “Combined” map has been updated to include the “Symptoms in Community (Facebook)” indicator.

• v1.2 Wednesday, May 20, 2020

  • New map: The “Combined” signal represents a statistical combination of the other indicators, not including the official reports (cases and deaths). For more information how this indicator is calculated, see the details above in the list of indicators.
  • New map: The “Symptoms in Community (Facebook)” map shows the estimated fraction of people who know someone with a COVID-like illness in their local community.
  • The “Surveys (Facebook)” map has been renamed “Symptoms (Facebook)”, to reflect that it asks respondents whether people in their household have COVID-like symptoms.
  • The “Surveys (Google)” map has been removed. This data is still available in the public Epidata API, but new data will not be collected.

• v1.1 Thursday, May 7, 2020

  • Time series plots now include shaded regions showing the standard error of the signal estimates, when available.
  • New map: The “Deaths (JHU)” map shows death ratios (deaths per 100,000 population) due to COVID-19 per day. This reflects official figures from state and local health authorities, as compiled by a team at Johns Hopkins University.
  • New map: The “Confirmed Cases (JHU)” map shows confirmed case ratios (cases per 100,000 population) of COVID-19 per day. This reflects official figures reporting cases confirmed by testing to be COVID-19, as compiled by a team at Johns Hopkins University.
  • The “Flu Testing (Quidel)” map is no longer shown. During flu season, rates of flu tests may have correlated with rates of COVID-like illnesses, as many doctors who suspected COVID-19 conducted flu tests to rule out influenza. However, the end of flu season means few flu tests are currently conducted.
  • Previously, the “Search Trends (Google)” signal reported search volume on each day on the map for the following day; for example, search volume on April 16 would be mapped as occurring on April 17. This is no longer done.

• v1.0 Friday, April 24, 2020

  • Initial public release of COVIDcast.
  • Includes maps of Doctor Visits, Facebook and Google surveys, Google search trends, and Quidel flu testing.
