December 5, 2021

Total cases: 1,536,351

Total deaths: 27,246

Los Angeles County ended last week with far more new COVID-19 cases than reported in the week before - the most since the end of September at the tail end of last summer's COVID-19 surge. Looking at the trends of this pandemic since March of last year, we are afraid to make the call that the winter surge is now on. Last year's horrific winter surge also kicked off in the week after Thanksgiving Day. However, in that week last year, the county counted more than 48,000 new cases. This week, one year later, the county counted less than 10,000 new cases - a considerable difference. We believe that we have the vaccines to thank for that.


New cases reported today: 1,642

7-Day Moving Average: 1,567 (previous day's 7-day average: 1,415)

New deaths reported today: 4

7-Day Moving Average: 17 (previous day's 7-day average: 17)
