COVID-19 Glossary of Terms
Synchronous learning: A remote learning environment where a teacher and a group of students are engaged in learning simultaneously.
Asynchronous learning: Students learn the same material at different times and locations. This could include pre-recorded videos or other learning materials.
In-person learning: Students are physically present in the classroom.
Remote learning/E-learning: Students are not physically present in the classroom. Learning could occur synchronously via video conferencing or asynchronously via videos, discussion boards or other learning materials.
Asymptomatic: Presenting no symptoms of the disease. In the case of COVID-19, the absence of fever, chills, cough, sore throat, shortness of breath, runny nose, stuffy nose and body aches, among other less common symptoms.
Symptomatic: Showing symptoms of COVID-19, which can include a fever, chills, cough, shortness of breath, runny nose, stuffy nose and body aches, among other less common symptoms.
Exposure period: The period in which an individual may have come in contact with the infectious agent. (COVID-19: 2–14 days before symptom onset. If asymptomatic, use the test date as the onset date.)
Incubation period: The period between when a person is infected and when they start to show symptoms of the disease. (COVID-19: 2–14 days after coming in contact with the virus.)
Infectious period: The period when a person infected with a disease can transmit the disease. (COVID-19: 48 hours before symptom onset through the end of the case’s isolation period.)
Close contact: Someone who was within 6 feet of an infected person for a cumulative total of 15 minutes or more over a 24-hour period* starting from 2 days before illness onset (or, for asymptomatic patients, 2 days prior to test specimen collection) until the time the patient is isolated. For LJCDS, this applies to those in the same classroom cohort.
Isolation: For people who are already sick/infected. The separation of sick people with a contagious disease from people who are not sick.
Quarantine: For people who are not sick but may have been exposed. The separation and restriction of the movement of people exposed to a contagious disease to see if they become sick.
Contact tracing: Process to identify situations in which an infected person is transmitting the coronavirus, and then warn others who have been exposed through that person.
Coronavirus: A type of microscopic organism that causes illness in humans. “Corona” alludes to the tiny spikes found on the surface of the virus, which scientists thought resembled a crown when seen through a microscope.
COVID-19: A shorthand way of referring to the novel Corona Virus Disease, an upper respiratory infection that was first identified in 2019. The germ that causes it is formally known as SARS-CoV-2.
Personal Protective Equipment (PPE): Equipment worn to minimize exposure to hazards that could cause workplace illness or injury.
Social/physical distancing: The practice of staying at least six feet away from other people, avoiding crowds and gatherings, and limiting or canceling all unnecessary travel to reduce the spread of disease.
