Superspreader events are key to #Covid19.
To limit the impact, we need to #StaySMART
S --> Stay home when sick
M--> Mask when out
A--> Avoid large gatherings
R--> Refresh indoor air
T--> Ten feet is better than six
Let& #39;s break this down...

To see why #StaySMART is a good control strategy, first have to recognize 3 things are happening,
1) 10% of people causing 80% of infections
2) airborne transmission is happening
3) indoor spaces are key risk factor

"10% of infectious people causing 80% of infections"
"As most infected individuals do not contribute to the expansion of epidemic, the effective reproduction number could be drastically reduced by preventing relatively rare superspreading events."

"airborne transmission is happening"
"Evidence for the potential for airborne transmission of SARS-CoV-19 continues to accumulate...Three lines of evidence support this conclusion."

M--> Mask when out
"The debate is over. You should be wearing a mask when out."
The public health benefits are fourfold:
1) prevent you from spreading
2) protect you from others
3) reminder not to touch face
4) normalize it

A--> Avoid large gatherings
“It is now pretty clear that large groups of people close together are good opportunities to spread the virus," - @mlipsitch
...banning mass gatherings may be enough to keep the pandemic in check..

R--> Refresh indoor air
"Here’s what we should be doing. First, bringing in more outdoor air in buildings...helps dilute airborne contaminants, making infection less likely.
For recirculated air, enhance the level of filtration."

T--> Ten feet is better than six
"First, maintain physical distancing. Six feet is good, but 10 feet is better."
Why? Basics of exposure science. Reduces the intensity of exposure.
