Indicator 1: Number of Days Since Contra Costa County Removed From State Monitoring List

Indicador 1: Cantidad de días desde que el Condado de Contra Costa fue eliminado de la lista de monitoreo del estado

Schools in counties in the State's widespread (purple) tier aren’t permitted to reopen for in-person instruction, unless they receive a waiver from their local health department for TK-6 grades. Schools can reopen for in-person instruction once their county has been in the Substantial (red) tier for at least two weeks. Schools must follow these State guidelines when they reopen or if they have to close again.

Indicator 2: Case Rate per 100,000 Population Over 14 Days (3-Day Lag) is Less Than 200

Indicador 2: La tasa de casos por cada 100,000 habitantes en los últimos 14 días (con un retraso de 3 días) es menor de 200

The State of California will not approve elementary school waivers in any county where the case rate per 100,000 population over 14 days (3 day lag) is 200 or higher. 

This is calculated as the total number of COVID-19 positive cases diagnosed and reported over a 14-day period, divided by the number of people living in the county. This number is then multiplied by 100,000.


Due to reporting delay, there is a 3-day lag. Although case rates are often calculated using the date they were reported to the health department, this measure uses the episode date. The episode date is the earliest of several dates and corresponds to the earliest date that the case can be known to have had the infection. Example: For cumulative case data received on 6/30/20, the reported 14-day case rate will be dated as 6/27/20 and will include cases with episode dates from 6/14-6/27.
