March 1, 2021: COVID-19 and Counterfeit N95 Mask

Dear Students:

In follow-up to the Feb. 26, 2021: Counterfeit Mask Notice email, this is reminder to check for counterfeit masks. Please check your N95 masks received from UMSON against the lot numbers below. 

The director of student and employee health at UMB recommends that any student who has worn a counterfeit 3M N95 respirator during patient care since Feb. 3, 2021, be tested for COVID-19. You can be tested on campus in Baltimore at the University of Maryland Medical Center Immediate Care, at the Southern Management Corporation Campus Center, or at the Baltimore Convention Center. Testing is also available at the University of Maryland Faculty Physicians Inc. office at Waterloo Crossing in Columbia, Maryland.   

Any student with a counterfeit mask needs to reach out to Bernie Shalit at for a replacement.
