Preliminary totals released by L.A. County reported about 7,000 new cases — the most in a single day, a sum that does not yet include new cases reported by Long Beach and Pasadena, which operate their own independent public health departments and will release their numbers later Tuesday. The previous single-day high for all of L.A. County was recorded on Nov. 23, according to The Times’ independent tally, with 6,186 cases.
