Despite gamers’ best intentions, the Hospital for Sick Children is asking that the public stop dropping Pokemon Go lures near or in SickKids.

In the augmented-reality mobile gaming phenomenon, lures are used to increase the spawning of Pokemon in specific areas. That makes them easier to catch for those who are unable to get outside and explore the city.

“We appreciate the positive intentions of Pokemon Go players who want to drop lures at SickKids,” the hospital said in a statement posted on Twitter. “Unfortunately Pokemon Go can create many challenging issues and safety concerns for our patients and may impede staff in their work.

“Our patients are some of the sickest in Ontario and may be going through a very difficult time in their lives. We ask that individuals respect their privacy and the hospital space.”

Last week, a post on Twitter encouraging people to drop lures near children’s hospitals was retweeted 60,000 times.

“There are plenty of kids who would love to go out and collect Pokemon, but they are stuck in bed, so this will help them,” the tweet read.

SickKids thanked gamers for their understanding and asked that lures not be dropped inside or outside the hospital.

Pokemon Go officially became available for both Android and iOS devices on Sunday.
