1/ This did not have to be.

Over 100,000 Americans currently in hospitals with COVID-19 and over 210,000 new cases today. We are converging on and will soon surpass the 9/11 death toll EVERY SINGLE DAY. And we are going to see a huge surge in the next several weeks & months.

2/ Hospital infrastructure is strained. Morgues have overflown. Front line health care workers are physically and mentally exhausted. This is a tragedy inside of a catastrophe.

3/ Despite all of this, too many people refuse to do what is needed to starve this virus of its hosts. Too many are too accepting of the death and devastation. Too many are fueling an inferno of infectiousness. It's all been said before, but ....

4/ Limit those in your household to immediate family. Isolate those in the family who show symptoms. Quarantine those who may have been in contact with an infector. Use a negative pressure zone for isolation (e.g., box fan in window pointing out).

5/ Employ portable HEPA filters and natural ventilation (if possible) outside of isolation zone. Avoid ALL non-essential indoor environments. Wear a mask in all essential indoor spaces you must visit and avoid those where universal mask wearing is not required and practiced.

6/ Avoid mass transit unless necessary for work or to get to essential needs. Transit authorities - open windows on buses. Ride share companies - open windows in vehicles and require masks for driver and passengers.

7/ Business owners, building owners, & building managers. Require masks for all. Do whatever you can to increase distancing in stores, offices, etc. Increase ventilation (open outdoor air dampers to extent possible; natural ventilation via window/door openings if not).

8/ Improve filtration in mechanical systems w/ upgrade to MERV-13 filters, if possible in system. In smaller buildings, stores, or smaller enclosed zones in buildings - consider one or multiple portable HEPA air cleaners with appropriate Clean Air Delivery Rate (CADR).

9/ Consider UVGI (proven technology if done right). Be innovative w/ staggered work hours in office building. If possible, design for air cleansing periods during day to reduce levels of any virus-laden aerosols (3/B hours; B = equivalent ACH from ventilation + filtration)

10/ Do as much outdoors as possible. And employers where it makes sense to do so, allow as much remote work as possible.

Don't underestimate the power of reminders. Keep repeating and reinforcing the importance of starving this virus of its hosts.

11/ Much of the aforementioned is relevant for schools. School-specific slides are provided under "Seminars" at http://www.corsiaq.com  (see below). These slides include a lot of links to other excellent resources.

12/ For those who have resources, do whatever you can to help employees and businesses in peril without going into non-essential indoor spaces. Take out. Big tips. Purchase gift cards for use six months from now. Maintain gym membership even when not attending, etc. Be generous.

13/ Policymakers/politicians. This is a time for profiles in courage. What you do for the next three months will define your legacy as a leader. Have a backbone. And for goodness sake, lead by example. Just do it!

14/ There are no words for the darkness that confronts us. We will get through this and to a better place. But for the next several months it is up to everyone to do their part to reduce the trail of death, suffering, grieving, and economic devastation. Please, just do it.
