BUTTE COUNTY, Calif. - Butte County Public Health (BCPH) said that testing for the delta variant is still very limited, but they have some data.

BCPH Communications Manager Lisa Almaguer said not all people who are tested for COVID-19 are tested for the delta variant.

Almaguer said testing for the delta variant is only at commercial labs and public health does not do the testing.

“Of the specimens that do get tested for a variant, the delta variant is now the dominant variant in Butte County and is responsible for 70.2% of specimens tested (sequenced) in the month of July, up from 26.8% in June,” Almaguer said.

Almaguer said this number is likely to be higher but the exact number of positive delta variant cases is not known.

BCPH only knows the percentage of test that comes back positive for the delta variant.

Kerri Shutte, Program Manager for Shasta County Health and Human Services, said the state had the health service send a couple of hundred cases for further testing and of the few hundred it sent, 80% were the delta variant.

According to the California COVID-19 website, over the last seven days, Butte County has reported 22.4 cases per 100,000 tests and Shasta County has reported 21.9 cases per 100,000 tests.

Over the last seven days, per 100,000 tests, Tehama County is reporting 19.5 cases, Glenn County is reporting 19 cases, Trinity County is reporting 11.8 cases and Modoc County is reporting 6 cases.

California is reporting 23.7 cases per 100,000 tests with a positivity rate of 6.5%.
