Update 12 Jan 2022 – Most of this is wildly out of date. It was useful back-in-the-day as reference points of definitions, links, and research papers, but I can’t really vouch for it now as being up to date.

Info
General facts and sources
| HCQ – concerning the French and Shanghai studies of it effectiveness against COVID-19 |
| Masks and their usefulness |
| Politifact – Coronavirus |
| SARS and MERS – incubation periods, treatments, comparisons with COVID-19 |
| Is COVID-19 the flu? * The flu killed 80,000 people in the U.S. last year (PolitiFact) – Mostly False. That number is not from any official report and the actual numbers are only estimates. * Comparing COVID-19 Deaths to Flu Deaths Is like Comparing Apples to Oranges (Scientific American) – “In the last six flu seasons, the CDC’s reported number of actual confirmed flu deaths has ranged from 3,448 to 15,620” |
| Terminology – vaccines, diseases, viruses |
| Blood oxygen level – Coronavirus FAQS: What’s A Pulse Oximeter? Is It A Good Idea To Buy One? – “You want a number in the 95% to 100% range. If the number drops to 92% or lower, that’s a cause for concern. That’s generally the level where a doctor might put you on supplementary oxygen and keep you in the hospital for observation.” |
Persistence on surfaces
Here’s how long the coronavirus will last on surfaces, and how to disinfect those surfaces. (Live Science) from 18 Mar 2020. The short answer (using the times from the currently active SARS-CoV-2):
• Air for up to 3 hours, half-life 1.1-1.2 hours.
• Copper for up to 4 hours
• Cardboard up to 1 day, half-life 3.2 hours.
• Plastic and stainless steel up to 3 days. Plastic half-life 6.8 hour, and stainless steel half-life 5.6 hours.
Long answer in chart below:
Dispersal and particles released
How much of the virus is dispersed from a person? – It may (only an estimate) take 1,000 particles to become infected. Amount that is dispersed in the table below:
| Type of Dispersal | Droplets Dispersed | Speed of Dispersal | Viral Particles Released | Distance |
|---|---|---|---|---|
| breathing | 50-5,000 | 20/min | several meters | |
| speaking | 500-50,000 | 200/min | several meters | |
| coughing | 3000 | 50 mph | 200 million | 10+ meters (small droplets) |
| sneezing | 30000 | 200 mph | 200 million | 10+ meters (small droplets) |
additions from It is Time to Address Airborne Transmission of COVID-19 (Oxford Academic, 6 Jul 2020), summarized Coronavirus can float in air and WHO and CDC should tell people that, experts say (CNN, 6 Jul 2020)
An important study regarding an early instance of airborne spread examines how 2 families in a restaurant in China became infected by a different family who sat in front of the A/C vent that blew air to the two.
Abstract
COVID-19 Outbreak Associated with Air Conditioning in Restaurant, Guangzhou, China, 2020 (Covid-19 Hub, 10 Feb 2020)
During January 26–February 10, 2020, an outbreak of 2019 novel coronavirus disease in an air-conditioned restaurant in Guangzhou, China, involved 3 family clusters. The airflow direction was consistent with droplet transmission. To prevent the spread of the virus in restaurants, we recommend increasing the distance between tables and improving ventilation.
