The Centers for Disease Control and Prevention (CDC) published new guidelines recommending that people wear a face mask indoors, regardless of vaccination status, in regions facing “high” or “substantial” Covid-19 transmission.
What is considered “high” or “substantial”?
Along with the new guidelines, CDC they published a Map which shows which areas are experiencing increasing rates of coronavirus.
For a county to be considered an area with “high” transmission rates, the total number of new cases per 100,000 people in the last seven days must be greater than 100.
In counties that are considered to have “substantial” transmission of COVID-19, the total number of new cases per 100,000 people in the past seven days should be between 50 and 99.99, the CDC map shows.
Risk level in the state of California
In the Central Valley, the counties of Merced, Madera, Fresno and Kings they are currently listed by the CDC as having “high” transmission rates. Meanwhile, the counties of Tulare and Mariposa they are “substantial”.
Southern California counties and the Bay Area also show high transmission rates, according to the map.
Cases are increasing in the United States as concerns mount about the Delta variant. According to an internal CDC document, this variant appears to cause more serious illness and is spread as easily as chickenpox, with each infected person, on average, infecting eight or nine others. The original lineage was as transmissible as the common cold, and each infected person transmitted the virus to two other people on average.
