We've designed an interactive COVID-19 trend tracker using data from the California Health Department.

The trends in this tracker directly impact a county's classification in the state's reopening system.

There are four tiers in the reopening system: yellow, orange, red and purple. Yellow indicates minimal COVID-19 spread and allows for nearly all businesses to reopen indoor operations (as long as physical distancing and face-covering requirements are in place). Purple means there is widespread COVID-19 transmission in the county and nearly all businesses have to keep indoor operations closed or severely limited.

While nothing official is announced, we now know a California curfew is on the table. So, what would a curfew look like if it happens? And how effective is it?



How a county is categorized depends on the number of new daily coronavirus cases and the testing positivity rate, or the proportion of those tested who turn back a positive result. Here's how it breaks down:

  • Widespread (purple): Counties with more than 7 daily new cases per 100,000 residents or higher than 8% positivity rate
  • Substantial (red): 4 to 7 daily new cases per 100,000 residents or 5-8% positivity
  • Moderate (orange): 1 to 3.9 daily new cases per 100,000 or 2-4.9% positivity
  • Minimal (yellow): Less than 1 daily new case per 100,000 or less than 2% positivity

Each color code has a different set of rules regarding what businesses are and aren't allowed to reopen, whether they can open indoors or outdoors, and at what capacity they can operate. Here's how it breaks down by category:

PURPLE


Nighttime curfew in effect from 10 p.m. to 5 a.m. until Dec. 21. Only essential activities allowed during overnight hours.
