Just found the population testing info from the Big 10's website. It's based on rolling 7 day averages so a recent outbreak would threaten this week less than say the week after. Things are only cancelled in a red/red scenario, but orange/orange and orange/red can lead to it as well.
The Big Ten Conference will use data provided by each Chief Infection Officer (CInO) to make decisions about the continuation of practice and competition, as determined by Test Positivity Rate and Population Positivity Rate, based on a seven-day rolling average:
- Test positivity rate (number of positive tests divided by total number of tests administered):
Green 0-2%
- Orange 2-5%
- Red >5%
[*]Population positivity rate (number of positive individuals divided by total population at risk):
Green 0-3.5%
- Orange 3.5-7.5%
- Red >7.5%
Decisions to alter or halt practice and competition will be based on the following scenarios:
- Green/Green and Green/Orange: Team continues with normal practice and competition.
- Orange/Orange and Orange/Red: Team must proceed with caution and enhance COVID-19 prevention (alter practice and meeting schedule, consider viability of continuing with scheduled competition).
- Red/Red: Team must stop regular practice and competition for a minimum of seven days and reassess metrics until improved.
