                This is also why it is critical for people who are symptomatic to stay home. Your sneezes and your coughs expel so much virus that you can infect a whole room of people.
What is the role of asymptomatic people in spreading the virus?
Symptomatic people are not the only way the virus is shed. We know that at least 44% of all infections—and the majority of community-acquired transmissions—occur from people without any symptoms (asymptomatic or pre-symptomatic people). You can be shedding the virus into the environment for up to five days before symptoms begin.
The amount of virus released from an infected person changes over the course of infection and it is also different from person-to- person. Viral load generally builds up to the point where the person becomes symptomatic. So just prior to symptoms showing, you
are releasing the most virus into the environment. Interestingly, the data shows that just 20% of infected people are responsible
for 99% of viral load that could potentially be released into the environment.
So now let’s get to the crux of it. Where are the personal dangers from reopening?
When you think of outbreak clusters, what are the big ones that come to mind? Most people would say cruise ships. But you would be wrong. Ship outbreaks, while concerning, don’t land in the top 50 outbreaks to date.
Ignoring the terrible outbreaks in nursing homes, we find that the biggest outbreaks are in prisons, religious ceremonies, and workplaces, such as meat packing facilities and call centers. Any environment that is enclosed, with poor air circulation and high density of people, spells trouble.
Some of the biggest super-spreading events are:
• Meat packing: In meat processing plants, densely packed workers must communicate to one another amidst the
