Return to Campus Glossary

As Cal State East Bay repopulates its campuses, the following glossary may provide clarity for the resumption of in-person operations. Additional terms related to COVID-19 and the pandemic are listed in a general glossary

Antibodies are proteins generated by the immune system in response to a threat. Antibodies can be generated by an infection or a vaccine and tend to be uniquely suited to battling a particular virus or other microbial invaders.

Antibody tests examine blood serum, which can reveal whether a person has antibodies to a particular disease, indicating they’ve had that disease. They are not used for determining if someone is currently infected. 

Asymptomatic describes a person who is infected but not feeling or exhibiting symptoms. 

Cleaning definitions from the CDC on cleaning vs. disinfecting vs. sanitizing:

  • Cleaning removes germs, dirt, and impurities from surfaces or objects. Cleaning works by using soap (or detergent) and water to physically remove germs from surfaces. This process does not necessarily kill germs, but by removing them, it lowers their numbers and the risk of spreading infection.
  • Disinfecting kills germs on surfaces or objects. Disinfecting works by using chemicals to kill germs on surfaces or objects. This process does not necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it can further lower the risk of spreading infection.
  • Sanitizing lowers the number of germs on surfaces or objects to a safe level, as judged by public health standards or requirements. This process works by either cleaning or disinfecting surfaces or objects to lower the risk of spreading infection. 

Contact tracing is what public health authorities use to track a virus's spread. It involves three steps.

  • First is contact identification. Once a person is infected and symptomatic with a disease, the person is asked about their activities and their interactions with others.
  • That's followed by contact listing. Once contacts with the infected person are identified, they're informed of their status and advised to get early care if they begin to develop symptoms. If they are considered high risk, they may also be advised to isolate themselves.
  • Finally, there is contact follow-up, where doctors get in touch with people who came into contact with the infected person to see if they begin to develop symptoms.

Essential businesses are those that serve a critical purpose including Cal State East Bay and other colleges and universities. 

Face coverings are cloth, bandana or other type of material that covers one’s mouth and nose.

Social distancing, which can also be referred as physical distancing, means maintaining greater space between oneself and others and/or avoiding direct contact with other people.

PPE is shorthand for personal protective equipment which is specialized clothing and equipment used as a safeguard against health hazards including exposure to infectious diseases through physical contact or airborne particles. It includes N95 masks and protective gloves. Most people don’t need PPE, but use Supplies to reduce health risks. 

Pre-symptomatic describes an infected individual who is not yet displaying symptoms of an illness or disease.

Presumptive case means that a local health agency has received a positive test result from a patient. Those results are awaiting confirmation from the CDC. 

Resolved refers to a case in which the person is no longer infected with the virus. 

Self-isolation is the act of separating oneself from others.

Self-quarantine is the act of refraining from any contact with other individuals for a period of time—in the case of COVID-19, two weeks—to observe whether any symptoms of the disease will arise after potential exposure.

Supplies include protective and disinfecting items such as plexiglass shields, face coverings and cleaning items. Area managers can obtain additional supplies to assist with clean and safe workspaces.  

WFH is an abbreviation of “working from home” or “work from home.”
