At least 44% of all infections--and the majority of community-acquired transmissions--occur from people without any symptoms (asymptomatic or pre-symptomatic ). You can shed the virus for up to 5 days before symptoms begin.

"Based on infectious dose studies with MERS & SARS, it is estimated that as few as 1000 SARS-CoV2 viral particles are needed for an infection."

Being around anyone infected. Entering a space where an infected person was. Touching something an infected person touched, then touching your face. There is more than one way to get infected.

Sitting still doesn't expel much virus. Speaking expels more. Coughing & sneezing spreads the virus rapidly. "The droplets in a single cough or sneeze may contain as many as 200M virus particles... A single sneeze releases ~30k droplets, with droplets traveling at up to 200 MPH."

A person infected with influenza sitting still releases 3-20 virus RNA copies/minute. Even if every virus ended up in your lungs, you'd need 50 minutes to get 1,000 copies.

But any activity raises the chances an infected person expels virus & you catch it. In one study under peer review, researchers used a model to estimate that a person standing and speaking in a room could release up to 114 infectious doses per hour.

You can get infected quickly indoors. If a person coughs or sneezes, those 200M viral particles go everywhere & can hang in the air for minutes. Enter a room soon after a cough/sneeze, take a few breaths & you have potentially received enough virus to establish an infection.

This is an important question as we reopen businesses. Studies show risk everywhere. Cruise ship outbreaks aren't even in the top 50 outbreaks to date. Nursing homes have obviously been terrible sources of deadly outbreaks.

You probably don't work in a meatpacking plant, but those are proving very dangerous. As of Friday, 190 meatpacking and processed food plants and four farms have confirmed cases of Covid-19. At least 13k workers have tested positive & 51 have died. ( https://thefern.org/2020/04/mapping-covid-19-in-meat-and-food-processing-plants/)
Restaurants: One study tracing a single outbreak found that one presymptomatic person infected 9 people from three families who had eaten at the same air-conditioned restaurant in Guangzhou, China. ( https://wwwnc.cdc.gov/eid/article/26/7/20-0764_article)
Open Offices: A single infected employee came to work in a call center. The floor had 216 employees. Over a week, 94 coworkers become infected. Almost all came from one side of the floor--only 5 who sat on the other side of the floor became infected. ( https://wwwnc.cdc.gov/eid/article/26/8/20-1274_article)
Indoor sports: An Edmonton curling tournament was held between March 11 and 14. By March 27, at least 24 of the roughly 72 attendees tested positive for COVID-19, and at least one healthcare worker had become infected treating patients.

Public restrooms have a lot of high-touch surfaces (door handles, faucets, stall doors). Also, the virus has been found in the feces of COVID-19 patients. We don't know if the virus in feces can cause COVID-19, but toilet flushing aerosolizes droplets. ( https://www.cdc.gov/coronavirus/2019-ncov/php/water.html)
Gatherings: A review of 54 superspreading events in 28 nations found:
- 19 involved parties or liquor-fueled festivals
- 9 were linked to religious services or missionary work
- 6 involved face-to-face business networking
- 5 involved funerals.

One study found that the odds that a primary case transmitted COVID-19 in a closed environment was 18.7 times greater compared to an open-air environment. ( https://www.medrxiv.org/content/10.1101/2020.02.28.20029272v2)

Another study found that homes were the riskiest place (where, if one family member becomes sick, others spend a LOT of time in contact with someone infected.) Shopping was relatively rare (but not zero!) And outdoor transmission was quite rare. ( https://www.medrxiv.org/content/10.1101/2020.04.04.20053058v1.full.pdf)
Get outside but be smart. Enjoy the sun. Just do so cautiously! Stay away from others. Wear masks. Social distance.
Socializing w/ a few family & friends should be okay, but don't throw the ball around, hand beers to others, hug, or sit close together.

And if you run, walk or bike, have a brain and some care for others. Don't exercise where it may be crowded. Give other people a lot of space. Stay on roads away from crowded sidewalks. Your need for carefree exercise shouldn't become someone else's stay in the hospital!

The choir decided to proceed with rehearsal but took precautions: Hand sanitizer at the door, no hugs & handshakes, & everyone brought their own sheet music. They spent 2.5 hours together. 45 got COVID-19, three have been hospitalized, and two are dead. ( https://www.latimes.com/world-nation/story/2020-03-29/coronavirus-choir-outbreak)

Wear your masks!
Wear your masks!
Wear your masks, not for you but everyone else. In a 2013 study of the influenza virus, it was found masks produced a 3.4 fold reduction in viral aerosol shedding. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3591312/
Be safe. Be cautious. And wear your damn masks when you're out and about!
