For the safety of all, students, faculty, and staff are expected to abide by personal safety practices known to prevent the spread of COVID-19.

Ways to Stay Safe

All students, faculty, and staff are expected to do the following regardless of vaccination status:

  • Wash your hands often with soap and water for at least 20 seconds, especially prior to eating. Hand sanitizer should be used if soap and water are not readily available.
  • Avoid touching your face with unwashed hands – including your eyes, nose, and mouth.
  • Avoid close contact with people and do not shake hands.
  • Adelphi University temporarily reinstated our indoor mask requirement for all individuals at our Garden City, Hauppauge, Hudson Valley and Manhattan locations, as of mid-May 2022.
    • As of June 6, indoor masking became optional, due to improving conditions.
  • Cover all coughs and sneezes, preferably with a tissue that can be discarded in a closed container after use. In absence of a tissue, use your sleeve or elbow.
  • Clean frequently touched surfaces and objects including buttons, door handles, counters, workstations, keyboards, etc.

Note: All visitors to campus will be expected to follow these guidelines.

For community members who are sick, the following is expected:

  • Stay home.
  • Students who test positive, suspect they may be ill, or have been in close contact with someone who tested positive should call Adelphi Health Services at 516.877.6000 for advice about next steps.
  • Faculty and staff should refer to our Stay at Home policy and feel free to reach out to Human Resources at 516.877.3220 and Health Services at 516.877.6000.
  • Keep sick household members away from others. If you have a separate room, that is best. Similar procedures and guidelines will be provided for residential students living on campus.
  • Avoid sharing personal items.
  • Anyone at high risk for complications or identifying as a member of a vulnerable population should speak with a designated Adelphi official.
  • Adelphi’s quarantine and isolation period has been reduced to reflect the guidance of the Centers for Disease Control and Prevention (CDC), New York state and the Nassau County Department of Health.
    • Those who test positive for COVID-19 should isolate for at least five complete days, wearing a mask when it is not possible to separate from others, followed by the use of a well-fitted mask when around others at home and in public for five additional days (days six through 10 after symptom onset).
    • Anyone not up-to-date on COVID-19 vaccinations and who has had close contact with someone with COVID-19 must stay home, away from others for at least five days after the date of the last contact with a person with COVID-19. Seek testing at least five days after the date of the last close contact, and wear a well-fitting mask around others for 10 days from the date of your last close contact with someone with COVID-19.

Guidance for Face Masks and Coverings

In situations where masks continue to be required, we strongly encourage the use of medical/surgical masks instead of cloth masks.

Appropriate use of face masks or coverings minimizes risk to others near you. To function properly, they must cover your mouth and nose, or you could spread COVID-19 to others—even if you do not feel sick. The mask or cloth face covering is not a substitute for social distancing or proper handwashing.

Adelphi follows the CDC recommendations for acceptable face coverings. They include but are not limited to cloth-based face coverings, two-ply gaiters and disposable masks that cover both the mouth and nose; bandanas and buffs are not acceptable face coverings, and masks with valves or vents do not offer adequate protection and should not be used while on campus.

How to Select a Mask

Choose masks that:

  • Have two or more layers of washable, breathable fabric
  • Completely cover your nose and mouth

Don’t choose masks that:

  • Are made of fabric that makes it hard to breathe, for example, vinyl
  • Have exhalation valves or vents, which allow virus particles to escape

Special Situations

If you wear glasses, find a mask that fits closely over your nose or one that has a nose wire to limit fogging.

Gaiters and Shields

  • Wear a gaiter with two layers, or fold it to make two layers
  • Face shields are not recommended: Evaluation of face shields is ongoing, but effectiveness is unknown at this time.

  • Find a mask that is made for children to help ensure proper fit.
  • Check to be sure the mask fits snugly over the nose and mouth and under the chin and that there are no gaps around the sides.
  • Do NOT put on children younger than 2 years old.

Use and Care of Face Coverings

Care, storage and laundering

  • Keep face coverings/disposable mask stored in a paper bag when not in use.
  • Cloth face coverings may not be used more than one day at a time and must be washed after use. Cloth face coverings should be properly laundered with regular clothing detergent before first use, and after each shift. Cloth face coverings should be replaced immediately if soiled, damaged (e.g. ripped, punctured) or visibly contaminated.
  • Disposable masks must not be used for more than one day and should be placed in the trash after your shift or if it is soiled, damaged (e.g., stretched ear loops, torn or punctured material) or visibly contaminated.
