COVID-19 Resource Guide

Fall Health Guidance

All Columbia affiliates must continue to wear masks at all times in indoor settings in Columbia facilities, regardless of vaccination status. Vaccinated individuals may remove masks and not physically distance only in outdoor settings on Columbia’s campuses. Unvaccinated individuals must continue to wear masks both indoors and outdoors. However, vaccinated individuals may choose to continue to wear masks outdoors on Columbia’s campuses and in crowded public settings, thus, no assumptions should be made regarding why an individual chooses to mask outdoors.

Statement on Omicron Variant

The University is closely monitoring emerging information on the Omicron variant, categorized as a variant of concern by the World Health Organization. Currently, there is limited information with regard to the ease of its transmission, whether it causes more severe illness, or whether it compromises the protection from current vaccines.

Be sure to read: What is Omicron and How Concerned Should We Be?

Please continue to take all precautions, including wearing a mask in public indoors, as well as in crowded outdoor contexts. Travelers should continue to follow CDC recommendations when traveling to and from the U.S. Additionally, COVID-19 vaccine booster doses are recommended for those who are eligible; visit to learn more about booster doses and where you can get one.

At this time, the University remains in Yellow Alert Level, and all in-person activities and instruction should continue with the current COVID-19 preventive measures in place.

Please join the Campus Update Forum on Tuesday, December 7 at 4:00 pm for updates on the COVID-19 pandemic and the Omicron variant.

COVID-19 Research at Columbia

Study on COVID-19 Vaccinations in Largest U.S. Cities Finds Stark Inequities

Researchers at Mailman School of Public Health find that high vaccination neighborhoods had more white residents, fewer people of color, higher incomes, and lower poverty rates.


Mailman Study Suggests COVID-19 Mortality Is Related to Health and Socioeconomic Factors

The findings show a strong association with the proportions of people with chronic kidney disease and those living in nursing homes, and support the idea that vaccine allocation could help minimize severe outcomes, particularly deaths.

Epidemiologists Find That Even Mild Cases of COVID-19 Affects Mental Health

A significant level of symptoms of depression, anxiety, and post-traumatic stress may follow the disease independent of any previous psychiatric diagnoses, according to new research by Columbia University Mailman School of Public Health.

New Study of Coronavirus Variants Predicts Virus Evolving

A new study of the U.K. and South Africa variants of SARS-CoV-2 predicts that current vaccines and certain monoclonal antibodies may be less effective at neutralizing these variants and that the new variants raise the specter that reinfections could be more likely.
