L.A. Public Health officials warn against trick-or-treating

The L.A. County Public Health Department has created guidelines for Halloween this year.

Health officials initially did not permit trick-or-treating, alongside other Halloween activities this year. The revised holiday guidelines reclassified the activity to “not recommended.”
“This year, it’s just not safe to celebrate in the ways we usually do,” L.A. County Public Health Director Barbara Ferrer said on Wednesday. “We are recommending that trick-or-treating not happen this year.”

County partners with SafePass app to further contact tracing efforts

Mayor Eric Garcetti announced a partnership between L.A. County and SafePass, an app that tracks those who may be exposed to coronavirus.

SafePass is offered through Citizen, a widely-used safety alerts app. Users will be notified of extended exposure to a known case and can track their own symptoms with SafePass.

The app does not identify the person who tested positive, according to Garcetti.

L.A. County’s testing positivity rate is starting to decline

As the number of cases climbed over the summer, the testing positivity rate is beginning to decline. Dr. Ferrer said the County has seen a less than 5% positivity rate — the lowest rate since the beginning of the pandemic.

Similarly, the hospitalization rate has steadily declined since peaks following July 4.
