Pivot Table based on specific values from multiple columns

Doing that would filter the "Humans" row as well. I need to perform that exact filter, but ONLY on the "Confirmed" row.

The data I am displaying is accurate, but the problem is when I double-click on a number, it shows all the records because I am using the "Sum Of" value which just adds all the 1s and 0s. Ideally, the columns would have "Yes"/"No" values and I would want to do a Count Of "Yes" values so drilling down would present a view filtered by the selected Region AND only the "Yes" rows
