She points out that, while these gatherings may be small, it's the "overlapping social groups" that are causing the disease to spread far and wide.

"Even though they may have been smaller individual parties, the overlapping groups meant that there’s a large number of people that were potentially exposed," Dr. Henry explained.

She compares the situation to Kelowna, where dozens of new cases are being confirmed as a direct result of parties and crowds at bars.
