• Antibody

• Virus

• Immunity

VACCINE

• When enough people in a population are immune to a disease,

• Staying at home voluntarily to help prevent the spread of disease.

• A biological preparation that provides immunity to a specific infectious agent.

When enough people in a population are immune to a disease, either by recovering from a previous infection or receiving a vaccine, so that the disease no longer spreads easily

• Quarantine

• Herd immunity

• Lockdown

A measure imposed by a government that prevents people from leaving a region in an attempt to control a disease outbreak.

• Outbreak

• Droplet transmission

• Lockdown

Asymptomatic:

• A person that is not showing any signs of having a disease despite being infected.

• When someone contracts a disease and the precise source of the infection cannot be found.

• The same as an epidemic but occurring over a more limited geographic area.

• Pandemic

• Epidemic

• Virus

A disease caused by an infectious agent that can pass between humans and other animals

• Lockdown

• Quarantine

• Zoonotic disease

VIRUS

• An infectious agent made of DNA or RNA inside of a protein envelope that can only grow and multiply by using the machinery of other cells.

• A group of related viruses that can infect mammals and birds.

• Severe acute respiratory syndrome coronavirus 2, the strain of coronavirus that causes COVID-19.

COVID-19:

• A disease caused by an infectious agent that can pass between humans and other animals.

• The disease caused by the virus SARS-CoV-2. The name comes from CO-rona-VI-rus D-isease along with the year it was discovered (2019).

• An infectious agent made of DNA or RNA inside of a protein envelope that can only grow and multiply by using the machinery of other cells.

Outbreak

• The same as an epidemic but occurring over a more limited geographic area.

• When someone contracts a disease and the precise source of the infection cannot be found.

• When bacteria or viruses travel within small drops of liquid from the respiratory tract.
