Perry and Beauchemin are being kept away from their teammates with their contagious condition, the Ducks said Tuesday. Both veterans are undergoing further medical tests.
Perry has missed the Ducks' last three games after falling seriously ill and requiring intravenous fluids from a local hospital last week. The former NHL MVP is still tied for the league lead with 11 goals heading into Tuesday's games.
Beauchemin missed Sunday's game against Vancouver.
Ducks captain Ryan Getzlaf missed one game last week along with Perry, but returned from his bout with illness.
Anaheim (10-3-3) hosts the defending Stanley Cup champion Los Angeles Kings on Wednesday in the season's first Freeway Faceoff.
