Philly’s coronavirus response

Updated maps track Philly’s positive COVID-19 cases by ZIP code

The city health department is updating numbers daily.

UPDATE: Please note that the Philadelphia Department of Public Health stopped updating these maps on June 2. They now track ZIP code data at this link.

Philly Health Commissioner Tom Farley announced on Mar. 27 that the coronavirus had officially spread to every part of the city.

So where in Philly are positive cases of COVID-19 most prevalent?

The city is publishing two versions of its incidence map, which you can check out below. The first shows actual number of tests done and how many returned positive, giving each ZIP code a “positivity rate.” The second compares the number of positive cases to the ZIP code’s overall population, giving a “per capita rate.”

Some important things to remember as you look at the geography, explained in detail after the maps:

  1. Test results lag behind actual spread
  2. Only a subset of people are being tested
  3. Stay home no matter where you are

Test results lag behind actual spread

Remember that the results shown on the map lag behind real time.

Daily reporting of test results was implemented in Philly on Mar. 8, the day after the region’s first positive case was confirmed in nearby Montgomery County. Since then testing has ramped up substantially.

Because those tests take time to process — approximately 5 to 7 days, according to Commissioner Farley — these results paint a picture of what the spread looked like a week or two ago.

Only a subset of people are being tested

Due to a lack of resources, including kits, masks and personal protective equipment, the Philly region’s 20 or so test sites are limiting who can get one.

In most cases, tests are being given to health care workers, first responders, folks over 50 showing symptoms of COVID-19, or people with underlying medical conditions.

So the ZIP code map really only shows the distribution among the above groups. The spread among the city’s general population could be different — but without widespread testing, we have no way to know.

Stay home no matter where you are

Even if you’re in a neighborhood that has a low positivity rate or low per capita count, you should assume the virus is circulating in your area.

That means you should take all possible precautions, both to avoid catching the debilitating disease yourself, and to avoid unconsciously spreading it around your community.

In case you haven’t already internalized those best practices:

  • Stay home unless you need to go out for essential reasons (food, work, medical, legal, safety)
  • When you go out to exercise or shop, maintain 6 to 10 feet of space between yourself and anyone who doesn’t live with you
  • Avoid touching surfaces as much as possible, especially nonporous plastic and metal, where the coronavirus can live in droplets of water for several days
  • When you return home, or as often as possible when you’re out, wash your hands for 20 seconds using soap and water
  • Wipe all other surfaces with disinfectant or soap, including cell phones and keys
