Characteristics of SARS-CoV-2 Positive Individuals in California From Two Periods During Notable Decline in Incident Infection

Despite declining SARS-CoV-2 incidence, continued epidemic monitoring is warranted. We collected SARS-CoV-2 test results from 150 drive-through testing centers across California from two observation periods: February 23rd-March 3rd 2021 and April 15th-April 30th 2021. We assessed SARS-CoV-2 positivity, stratified by Hispanic heritage among sociodemographic characteristics and potential exposures. We analyzed 114,789 test results (5.1% and 2.6% positive during the respective observation periods). Nearly half of all positive tests were among testers reporting a recent exposure (48.8% and 45.3% during the respective observation periods). Those findings may provide insight into evolving local transmission dynamics and support targeted public health strategies.
