![]() The number of diagnostic tests is incorporated as a covariate into the surveillance model to adjust for changes in testing volume over time. This Rt-estim-gamma model by Isaac Goldstein and Volodymyr Minin at UC Irvine and Jon Wakefield at University of Washington is a branching process inspired model where cases are modeled as noisy realizations of latent unobserved incidence. It has corrections to account for lags in diagnosis, disease duration and mortality risk. Users can download the LEMMA package and input their own data and priors for parameters using R or a simple Excel interface.Ĭovidestim calculates state-level effective reproductive numbers, taking cases, deaths and test positivity rates as inputs. LEMMA provides credibility intervals and scenarios for future cases, hospitalization, ICU, deaths and Rt. The model is calibrated to hospitalization, ICU and death data using Bayesian methods. LEMMA is an open-source SEIR model with compartments for hospitalization and symptom severity. CDPH-associated labs and public health labs throughout California use Terra to analyze and store SARS-CoV-2 sequences. **Terra is a cloud-native platform for biomedical researchers to access data, run analysis tools, and collaborate. The dataset is maintained by CDPH and is also used to update the Variants - Coronavirus COVID-19 Dashboard on SARS-CoV-2 trends occurring in California. *Integrated Genomic Epidemiology Dataset (IGED) includes a comprehensive record of California SARS-CoV-2 lineages derived using whole genome sequencing along with case demographic and epidemiologic information reported to the state per updates to Title 17 of the California Code of Regulations, section 2505, subsection (q). ![]() Projections may fluctuate week to week as new data is generated, lineages are re-designated, data backlogs and errors are resolved, and new variants are identified. Because sequencing SARS-CoV-2 samples takes time, observed variant proportions are lagged from the present date, generally by 3-4 weeks, and models are used to project current variant proportions. Variant proportions are estimated weekly for the past 3 months with weeks defined each Wednesday to align with data updates that occur each Tuesday. Variant proportions are derived from both the Integrated Genomic Epidemiology Dataset (IGED)* and Terra**. CDC COVID-19 Transmission Map by County Click on a county below for more information, or search for a county in the table.Starting on July 19, 2023, this page will be updated on a bi-weekly schedule to align with the cadence of CDC Nowcast updates. Southern California and Bay Area counties also show high transmission rates, according to the map. Meanwhile, Tulare and Mariposa counties are "substantial." In the Central Valley, Merced, Madera, Fresno and Kings counties are all currently listed by the CDC as having "high" transmission rates. ![]() In counties considered to have "substantial" COVID-19 transmission, the total number of new cases per 100,000 people in the last seven days must be between 50 and 99.99, the CDC map shows. For a county to be considered an area with "high" transmission rates, the total number of new cases per 100,000 people in the past seven days must be greater than 100. ![]() The CDC released new guidelines recommending that people wear masks indoors, regardless of vaccination status, in regions facing "high" or "substantial" COVID-19 transmission.īut what constitutes as "high" or "substantial?" And what parts of the United States and more specifically, Central California, are seeing these high rates of COVID-19?Īlong with the new guidelines, the CDC released a map showing which areas are experiencing surging COVID rates.
