What is COVID-19?

Covid-19 Explained

COVID-19 is a type of virus called a coronavirus. Coronaviruses are a large family of viruses that are known to cause illnesses ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS).

The novel coronavirus (COVID-19) is caused by a new strain of coronavirus (SARS-CoV-2) that has not been previously identified in humans. It was first identified in 2019 in Wuhan, China. As of October 1, 2020, more than 34 million people worldwide have been infected with COVID-19.

COVID-19 is highly contagious and is a potentially serious disease that causes a variety of symptoms including:

  • Fever or Chills
  • Cough
  • Headache
  • Fatigue
  • Sore Throat
  • Diarrhea
  • Muscle or Body aches
  • Nausea or vomiting
  • New loss of taste or smell
  • Congestion or runny nose
  • Shortness of breath or difficulty in breathing
  • Conjunctivitis
  • A rash on skin, or discoloration of fingers or toes
  • Pneumonia


How COVID-19 Spreads

When a person infected with COVID-19 coughs or sneezes, small droplets that contain the virus may be released into the air. These droplets can enter the mouths or noses of people nearby and make them sick. This is more likely to happen when people are within 6 feet of one another.

Why Test Passengers For COVID-19?

Passengers are often confined to spaces smaller than 6 feet apart, making them more high risk to be infected and spread the virus.

Types Of COVID-19 Tests

At Same Day Laboratories, we offer different COVID-19 tests, including those that can provide results while you wait. We offer the following COVID-19 tests:

  • Polymerase Chain Reaction (PCR) Test

With the PCR test, a sterile swab is inserted into your nose to take a sample. The swab is then placed in a tube and inserted in a machine for testing. Results are available in 2-3 hours.


  • Rapid Nasal Swab Test

Like the PCR test, a sterile swab is inserted into your nose to take a sample, and the sample is checked for active COVID-19 virus in a tube and cassette that does not need to go into a machine for testing. Results are available in no time.


  • Blood Antibody Test

Using a blood draw or a small prick of your finger, this test looks for markers in the blood that suggest you may have had the virus. Called “antibodies”, these markers can tell if you have been exposed to COVID-19 even if you don’t have symptoms.
