Researchers have found that dividing large groups into smaller sub-groups that don't intermix can help contain COVID-19.
The limiting of interactions without wider lockdowns helps stop the spread of the virus.
These findings were shared in an analysis published Tuesday by the journal Chaos.
According to UPI, the goal is to limit "random" interactions between people in affected communities.
As a result, these separations can curtail the spread of disease before it can expand across larger areas and populations.
