The Basics

The Difference Between COVID-19 and SARS-CoV-2

It can be very important to distinguish between diseases and their causative agents. Viruses and the diseases caused by them often have different names in order to facilitate accurate discussion regarding testing, treatment, spread, transmissibility, and severity of disease and infection.

​The virus that causes the disease is SARS-CoV-2:

– Severe
A  – Acute
– Respiratory
– Syndrome (related)
Co – Corona
– Virus
– The second virus to be termed SARS

​The disease state is ​COVID-19:

​CO – Corona
VI  – Virus
D – Disease
19 – The year in which the outbreak began (2019)

Tests can be broken down into two basic categories: Diagnostic and Serology (Antibody)

Diagnostic tests can be used to determine if you have an active coronavirus infection. These tests can be used by your healthcare provider or governing bodies to determine the next steps you should take regarding quarantine or isolation from others. There are two types of diagnostic tests for the detection of SARS-CoV-2: molecular and antigen.

Molecular tests detect viral genetic material which allow the virus to produce proteins and replicate during infection. The most common of these tests are polymerase chain reaction (PCR) tests. Generally speaking, molecular tests are the most sensitive and accurate.

Antigen tests detect specific viral proteins known as antigens. Antigen tests tend to be highly specific but are typically less sensitive than molecular diagnostic tests
*Antigens are the proteins that our bodies use to detect pathogenic material and mount an immune response and produce antibodies. The antibodies produced are specific to the antigen(s) detected and will specifically bind to the antigens to prevent an interaction of the antigen with healthy cells.*

Serology tests detect antibodies produced from the immune response that bind specifically to SARS-CoV-2 antigens. While diagnostic tests detect the presence of virus, serology tests detect the body’s response to the virus. This means that serology/antibody tests should not be used for diagnostic purposes.
*We do not know how long antibodies stay in the body following infection with the virus that causes COVID-19. We do not know if antibodies give you protective immunity against the virus, so results from a serology test should not be used to find out if you have immunity from the virus. The FDA cautions patients against using the results from any serology test as an indication that they can stop taking steps to protect themselves and others, such as stopping social distancing or discontinuing wearing masks.*

According to the CDC, it is suggested that the following circumstances are reasons for testing:

      • People who have symptoms of COVID-19.
      • Most people who have had close contact (within 6 feet for a total of 15 minutes or more over a 24-hour period) with someone with confirmed COVID-19.
        • Fully vaccinated people with no COVID-19 symptoms do not need to be tested following an exposure to someone with COVID-19.
        • People who have tested positive for COVID-19 within the past 3 months and recovered do not need to get tested following an exposure as long as they do not develop new symptoms.
      • People who have taken part in activities that put them at higher risk for COVID-19 because they cannot physically distance as needed to avoid exposure, such as travel, attending large social or mass gatherings, or being in crowded or poorly-ventilated indoor settings.
      • People who have been asked or referred to get tested by their healthcare provider, or state, tribal, local, or territorial health department.

CDC recommends that anyone with any signs or symptoms of COVID-19 get tested, regardless of vaccination status or prior infection. If you get tested because you have symptoms or were potentially exposed to the virus, you should stay away from others pending test results and follow the advice of your health care provider or a public health professional.

People with COVID-19 have had a wide range of symptoms reported – ranging from mild symptoms to severe illness. Symptoms may appear 2-14 days after exposure to the virus. Anyone can have mild to severe symptoms. According to the CDC, people with these symptoms may have COVID-19:

      • Fever or chills
      • Cough
      • Shortness of breath or difficulty breathing
      • Fatigue
      • Muscle or body aches
      • Headache
      • New loss of taste or smell
      • Sore throat
      • Congestion or runny nose
      • Nausea or vomiting
      • Diarrhea

This list does not include all possible symptoms. CDC will continue to update this list as we learn more about COVID-19. Older adults and people who have severe underlying medical conditions like heart or lung disease or diabetes seem to be at higher risk for developing more serious complications from COVID-19 illness.

If you suspect you have COVID-19 separate yourself from others

    • As much as possible, stay in a specific room and away from other people and pets in your home. If possible, you should use a separate bathroom. If you need to be around other people or animals in or outside of the home, wear a mask.
    • Tell your close contacts that they may have been exposed to COVID-19. An infected person can spread COVID-19 starting 48 hours (or 2 days) before the person has any symptoms or tests positive. By letting your close contacts know they may have been exposed to COVID-19, you are helping to protect everyone.

If you are sick, stay home except to receive medical care

    • Stay home. Most people with COVID-19 have mild illness and can recover at home without medical care. Do not leave your home, except to get medical care. Do not visit public areas.
    • Take care of yourself. Get rest and stay hydrated. Take over-the-counter medicines, such as acetaminophen, to help you feel better.
    • Stay in touch with your doctor. Call before you get medical care. Be sure to get care if you have trouble breathing, or have any other emergency warning signs, or if you think it is an emergency.
    • Avoid public transportation, ride-sharing, or taxis.
