Antibodies are specific blood proteins produced to respond and attack viruses in a person. Typically, humans develop antibodies after contracting the virus they’re attacking.


Some people contract viruses and do not display symptoms. Asymptomatic people can unknowingly spread viruses to other people, which is why wearing a mask is so important.


Balance Billing

Balance billing often occurs when a patient is receiving out-of-network care but doesn’t realize it. The patient then receives a “surprise” bill for services their insurance won’t cover.


Benefits are the services or items covered under a health insurance plan.

Block Grant

Unlike the current system, where Medicaid funding is based on the State’s actual expenditure on the program, and is shared by the state and the federal government, a block grant caps the amount that a state receives for Medicaid.


Children’s Health Insurance Program (CHIP)

CHIP is a government program that provides health insurance to children from lower-income families.


COBRA temporarily allows you to keep your employer-based insurance after your employment ends. You’re obligated to pay 100% of the premiums, including the portion the employer used to contribute.


The percentage of costs of a covered health service you pay once you’ve met your deductible. For example, if you have healthcare services that cost $10,000 and your deductible is $3,000 and your coinsurance is 20%, you’ll pay 20% of the remaining $7,000, or $1,400.

Community Mitigation

Community mitigation is a framework for preventing the spread of a virus by enacting measures such as closing restaurants, mandating the wearing of face masks while out, and reduced capacity at essential businesses like grocery stores.

Contact Tracing

Contact tracing is a technique used by health departments where volunteers identify someone infected by a virus and everyone they may have been in contact with in order to better control the spread of the virus.

Containment Zone

A containment zone is an area where movement is restricted and certain restaurants, stores, and other establishments may be closed.


A co-pay (or co-payment) is your share of the payment for a medical expense. For example, if a doctor charges $150 for a visit, insurance may pay $125 of the fee and the patient’s co-pay is $25

Cost-Sharing Reduction (CSR)

CSR payments are government subsidies paid to insurers to help keep premiums low for lower-income Americans.



A deductible is an amount that you have to pay before your insurance starts paying for your healthcare. For example, if your deductible is $2,000, your insurance company starts paying only after you have paid for the first $2,000 worth of medical bills.


A dependent is someone who relies on your health insurance, such as a spouse or child.


DSH payments (Disproportionate Share Hospital) are payments made by the federal government to hospitals that serve Medicaid and uninsured patients, to help cover uncompensated care costs that they incur in serving these vulnerable populations.

Health Equity

Health equity means that all humans have fair and just access to quality healthcare and the ability to stay healthy.


A health maintenance organization (HMO) is a type of health plan with which you choose a primary care physician, and all healthcare has to go through them (you can receive referrals to see specialists).


A health reimbursement arrangement (HRA) is an account that only your employer can contribute to, that helps you pay for qualified medical care that isn’t covered under your own healthcare plan.


A health savings account (HSA) is a personal savings account that you and your employer both contribute to that helps you save for out-of-pocket medical expenses.



Immunization — or vaccination — is the process where a person is made immune or resistant to an infectious disease, typically by administering a vaccine.

Infection Rate

An infection rate is a calculation of how many people within a certain population will become infected by a particular illness. The higher the infection rate, the more people are likely to become sick.

Inpatient Service

Any medical service that’s administered during a hospital stay, where room and board are charged.



Medicaid is a government program for lower-income Americans that provides free or low-cost health insurance.


Medicare is a government program for Americans 65 years or older that helps cover certain medical expenses.

Molecular Tests

Molecular tests are given to identify whether or not someone has contracted an infectious disease. These tests are also used to identify the likelihood of someone developing specific diseases or disorders, such as cancer.


N95 mask

N95 masks are the most common surgical facemasks, and filter at least 95% of airborne particles. While these facemasks are necessary for healthcare workers, everyone should wear a mask when out in public.

Your premium is the fixed amount you pay for your health insurance every single month whether you use your insurance or not.


Qualifying Life Event

Dramatic changes in your life that might occur that makes you eligible for a “special enrollment period” for insurance.



The R-naught, or reproductive number of a disease, is the estimated number of cases directly transmitted by one case. For example, if the R-naught is greater than 1, every infected person will infect one more person.


An insurance policy health insurers purchase to protect them from high claims, thus protecting healthcare consumers.


Serology Test

A serology test is a test for whether or not a person has contracted a virus, and now has antibodies that can fight the virus. These tests are important to know how many people have contracted a particular virus and recovered safely.

Social Distancing

Social distancing is the practice of maintaining a specific amount of distance (the recommendation for COVID-19 is six feet) from other people to prevent the spread of an airborne illness.
