Modified alternative scenarios:
- The base case is no longer added to alternate scenarios
- HEPA/FFP2 options revised to make more sense
If using FFP2, no alternatives are added.
If using HEPA and FFP2, HEPA + Type 1 is included as an alternate
If using HEPA and Type I, HEPA + FFP2 is included as an alternate
