Lessons learned from California as coronavirus cases surge

Although California appeared to be on track in March to become a coronavirus disaster, the state managed to turn things around — only to find cases skyrocketing three months later.

Between the lines: It's obvious what caused the problem in states like Arizona, Texas and Florida, where the warnings of public health officials were largely disregarded. But in California, there's not just one clear-cut explanation, the MIT Technology Review reports.

What happened:

1. There are large ethnic disparities, with infections concentrated within low-income communities.
2. People became lax about safety measures like social distancing and mask-wearing.
3. There's a large number of prison cases.
4. Some patients are coming from other places, including Mexico.

Between the lines: California avoided becoming a hotspot early on, but cases had been steadily rising long before they began rapidly spiking, as my colleagues Andrew Witherspoon and Sam Baker reported.
