A new study from the University of Cambridge finds that 50% or more mask users, combined w periodic shelter in place can effectively and dramatically reduce the reproduction rate, or r number(r = 2 means that on average each person with an infection passes it to two additional people).
Key takeaways of the study are:
“100 percent mask adoption combined with on/off lockdowns prevented any further disease resurgence for the 18 months required for a possible vaccine.” and also, “The models suggest that – while the sooner, the better – a policy of total face mask adoption can still prevent a second wave even if it is not instigated until 120 days after an epidemic begins.”
