New Maps Show Just How Fast Delta Variant Has Spread In Just One Month
More than 98% of US residents now live in an area where there is a “high” or “substantial” risk of Covid-19 community transmission, up from 19% of residents only a month ago. This sharp turn has been driven in large part by the highly infectious Delta variant and low vaccination rates in many regions.
The Centers for Disease Control and Prevention (CDC) measures community transmission using two metrics — the number of cases per 100,000 people and the test positivity rate, both measured over the previous seven days.
The latest figures from the CDC show an alarming rise in the number of counties that are considered at high risk of community transmission. On Monday, 2,361 counties in the United States were listed in the “high” tier, a stark increase from 457 counties in the same tier at the beginning of July. A look at the past five weeks shows just how rapidly community transmission has increased across the country.

The increase in community transmission has led to renewed mask mandates and an urgent push for vaccinations across the country, especially in areas where vaccination rates are low. The CDC now recommends that people wear masks indoors if they are in areas with “substantial” or “high” levels of spread, regardless of whether or not they are vaccinated. You can look up your county’s transmission level on the CDC’s website, which updates multiple times per week.

The graphic below indicates the spread of the Delta Virus from Low (Blue) and Moderate (Yellow) to Substantial (Orange) and High (Red). The top two maps represent the week of July 5 – 12th, with the subsequent pairs indicated the following weeks and concluding on August 6th.
Vaccines are the most effective tool in combating the spread of the new Delta variant, according to available data, with studies indicating that all three commonly available vaccines are able to prevent severe illness or death from Covid-19.
