Local Outbreak Data

The Public Health Department collects data on workplaces in Nevada County that have positive cases and outbreaks. An outbreak is defined as 3 or more cases in a 14-day period. Below are two charts related to positive cases at workplaces. We will update these charts monthly with the previous month's data. 

Table: COVID-19 Outbreaks by NAICS Sector. The law changed on January 1, 2021, and AB 685 now requires businesses to report workplace outbreaks to the public health department. We do not release the names of any individual businesses that report outbreaks to us. That information remains confidential. These reports are reported categorized by NAICS sector code, per AB 685 requirements. This table includes data from Jan 1, 2021 forward. We continue to work to get the word out regarding reporting requirements, we know that all business are not aware of the changes mandated by AB 685. 

The data below represent what has been self-reported by businesses, as required by AB685. However, we understand that self-reporting means that it is likely undercounting actual outbreaks that have occurred in Nevada County and we assume it to be incomplete.
