UPDATED As of 3 p.m. – ALL NIU Employees, Students and Guests to Wear Masks Indoors
July 28, 2021


DeKalb County has now been designated by the Centers for Disease Control and Prevention (CDC) as a location with “substantial” levels of COVID-19 transmission. Effectively immediately, all NIU employees, students and guests, whether vaccinated or not, are required to wear masks indoors.  The only exception to this is for individuals alone in their private work or living spaces.


This remains a very dynamic situation, and the university will continue to monitor closely and provide timely updates.


Please note the following:


  • To address the rising number of COVID-19 cases, the CDC and Illinois Department of Public Health (IDPH) are tracking and documenting COVID-19 transmission rates by county on a COVID-19 tracker website. Each county’s COVID-19 transmission levels are rated as either high (red), substantial (orange), moderate (yellow) or low (blue). 


  • Those who are vaccinated and live or work in the “high” or “substantial” areas should resume wearing masks indoors immediately.


  • Getting vaccinated remains the most safe and proven way to prevent severe illness, hospitalizations and death from COVID-19. With the highly transmissible Delta variant, this is more urgent than ever. Visit to find a vaccination location closest to you.


Huskies should not make assumptions, question, judge or discriminate against others regarding masks or vaccination status. Guidance on masking for the fall semester will be released closer to the start of classes.
