All visitors will be required to enter through one of three locations, with all other doors being closed to outdoor entry, said a news report. Visitors will have to provide a photo ID at a security desk at the entrance and will receive a sticker that states exactly which floor they are going to.

Visitors who enter through the Emergency Department will also have to show ID, and only two visitors will be allowed with each emergency department patient.

The hospital said it was not increasing security in response to any problems.
