New COVID-related rules on indoor and outdoor gatherings will take effect in New York on Monday. 

The new gathering guidelines state that indoor events with up to 100 guests will not be required to have COVID tests for guests beforehand, and indoor events with 101-150 guests must continue to follow enhanced COVID protocols, which includes testing. 

Outdoor events are allowed to expand to 200 guests, and these events do not have to follow the enhanced testing protocols. 

Starting April 2, outdoor events up to 200 guests do not have to follow the enhanced protocols, and outdoor events with 201-500 guests may be held, following enhanced COVID protocols.
