The CovidReduce Scenario spreadsheets are made available on an as-is basis without guarantee or warranty of any kind,
express or implied. Neither the authors nor reviewers accept any liability resulting from the use of tools or its
documentation. This is a decision-support tool that will be revised as the science surrounding airborne transmission of
SARS-CoV-2 and other pathogens advances. There is no "safe Covid exposure". You can use the spreadsheet tools to
determine what actions dramatically reduce risk to a low level if a spreader present. Implementation of Covid Reduce
scenarios spreadsheet tools and interpretation of its calculations are the sole responsibility of the user.
Education for the public and schools. Our STEM education programs empower 8th to 12th graders to understand and
reduce airborne infection in schools and at home.
In democracies we must make the science understandable so individuals can be informed to "choose wisely" and take actions
that keep their families safer while preserving as much of "normal life" and economic productivity as possible.
Science Technology Education Mathematics (STEM) programs will empower eighth to twelfth graders to understand the
pragmatics of infection risk reduction through hands on "sink top" and in classroom experiments. They will learn about
infection/environment and quantitative monitoring of airborne spread in a 1-5 hour education program.
1. Basics of airborne infection control overview, concepts and key past results;
2. Airborne spread desktop/sinktop simulator matching computational fluid dynamics;
3. Airborne spread in classroom and outside experiments; CO2,
aerosol, odor, and
smoke experiments in masking and ventilation;
4. Mask protection factors, fitting, and reuse; Daily infection reduction and
planning on how to reduce infection risk (quanta);
5. School/home assessment, monitoring quanta risk, cost benefit
tradeoffs and protection of vulnerable people.
Below are some figures of the airborne spread desktop/sinktop simulator:
