- Only requirement - mask in attendees' possession
- Counties with highest # of rally attendees
§7-13% increase in CV-19 cases §Compared to counties with low attendees
- Assuming all Sturgis CV-19 cases were non-fatal
§Estimated “public health costs ≈ $12 billion”
SLIDE 15 Trump Rallies – 18 Large Group Meetings
- Effects of subsequent CV19 within pertinent communities
§Controls similar counties
- Analysis up to 10 weeks post-rally for each event
- Complicated math models
- Estimate rallies increased confirmed cases of CV-19 by
>250 per 100,000 residents
- Extrapolating to entire sample
§>30,000 incremental confirmed cases of COVID-19 §>700 deaths (not necessarily among attendees)

SLIDE 19 Indoor Facilities Recommendations
- 4 D’s – Double Distance & Don’t Draft
- Equipment wipe downs & alcohol hand sanitizer
- High volume air turn over
§ HVAC with HEPA filters § Fans § Windows open
- Limit numbers in facility
- Mask up
- Entry screening
§ CV rapid testing?
- Keep entry log for contact tracing
SLIDE 20 Protect yourself and others
- The best way to prevent CV-19 is to avoid being exposed
- You can take steps to slow the spread
§ Outdoors & spaces with good ventilation reduce risk § Avoid crowded indoor spaces & ensure indoor spaces are properly ventilated by bringing in outdoor air as much as possible § Stay at least 6 feet away from others § Cover your mouth and nose with a mask when around others § Wash your hands often with soap & water or use a hand sanitizer with > 60% alcohol § Stay home and isolate from others when sick § Routinely clean & disinfect frequently touched surfaces
