The COVID-19 Travel Map has changed markedly in the last several weeks. Below you’ll see three maps: one from May 27th, the second from June 17th, and the third using data from July 11th.
Notice that on the last map in this set there are now four states, Arizona, Louisiana, Florida, and South Carolina where every county is in the “High” incidence rate class. There also large areas, like West Texas, that were barely touched by the virus back in May and are now seeing significant increases in cases.
Areas on this map with red fill, heavy black outline, and a maroon filled square inside are experiencing high numbers of new cases, substantial growth in new cases, and high rates of death per 100,000 people. Areas with blue fill and a gray open circle have experienced no COVID-19 deaths or new cases in the past two weeks.
Map Explanation:
These COVID-19 Travel Map are based on data from Johns Hopkins University, based on the two weeks prior to the map date.
The three layers on the map are:
Two-Week Cumulative Incidence Rate: A color fill indicating the number of new cases per 100,000 people in the two-week period. The value is the sum of each county’s number of reported cases in the past two weeks (in other words, the difference between the total number of cases from two weeks ago from the current total number of cases) divided by that region’s population. The resulting rate is multiplied by 100,000 to get a two-week cumulative incidence rate per 100,000 people.
0 cases past two weeks/blue: No confirmed cases reported in the past two weeks
Low/green: There have been 10 or fewer new cases per 100,000 people in the past two weeks.
Moderate/yellow: There have been between 10 and 50 new cases per 100,000 people in the past two weeks.
Moderately high/orange: There have been between 50 and 100 new cases per 100,000 people in the past two weeks.
High/red: There have been more than 100 new cases per 100,000 people in the past two weeks.
Two-Week Incidence Rate Trend: An outline for areas indicating how quickly new cases are growing. The bold outline is for areas growing at a rate of more than 30 new cases per 100,000 people per week. The light outline is for areas with growth in new cases of between 6 and 30 per 100,000 people per week. Areas without an outline may be relatively stable or have declining incidence rate trends.
Two-Week Cumulative Death Rate: A symbol for each area to indicate deaths per 100,000 people in the past two weeks.
0 deaths past two weeks/White circle: No deaths reported in the past two weeks
Low/open maroon circle: There have been less than 0.6 deaths per 100,000 people in the past two weeks.
Moderate/open maroon triangle: There have been between 0.6 and 3 new deaths per 100,000 people in the past two weeks.
Moderately high/filled maroon triangle: There have been between 3 and 6 new deaths per 100,000 people in the past two weeks.
High/filled maroon square: There have been more than 6 new deaths per 100,000 people in the past two weeks.
Changes in Death Rate Class:
The Death Rate Class Map has changed as well. Cities like Phoenix and Miami are now in the “High” death rate class, and Los Angeles is on trend to join them in two weeks or so.
For the maps above, population data is from the U.S. Department of Commerce, U.S. Census Bureau; raw COVID-19 data is from the COVID-19 Data Repository by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University.
