Medically reviewed by Carina Fung, PharmD, BCPPS

What is coronavirus disease (COVID-19)?

COVID-19 (short for coronavirus disease 2019), has already spread worldwide in early 2020. SARS-CoV-2, the virus itself (rather than the disease) is the most recently discovered strain in a family of viruses that caused severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS).1

According to the Centers for Disease Control (CDC), which is updating its coronavirus webpage with new information daily,2 SARS-CoV-2 was first detected in Wuhan, China, in late 2019. By March 11th, 2020, the World Health Organization (WHO) had declared the coronavirus outbreak a global pandemic.3 By March 13th, 2020 President Trump had declared the outbreak a national emergency for the U.S.4

What are the symptoms of coronavirus disease 2019 (COVID-19)?

According to the CDC, the symptoms of COVID-19 may be mild (similar to those of the common cold or seasonal flu) or severe. These symptoms may occur within 2–14 days after exposure to the virus.5

Symptoms may include:

  • Fever
  • Cough
  • Shortness of breath
  • Chest pressure or pain
  • Chills
  • Repeated shaking with chills

After 14 days, the more severe symptoms of COVID-19 may begin to appear. These are different from the symptoms of the common cold or flu, and may include:

  • Difficulty breathing
  • Chronic pain or pressure in the chest
  • Lack of energy and/or awareness

The risk of severe illness from COVID-19 increases as you get older. In the most serious cases, coronavirus can lead to pneumonia and even acute respiratory distress syndrome (ARDS), which may be the leading cause of death in immunocompromised or older patients.

The emergency warning signs of COVID-19 that require immediate medical attention include:

  • Having a hard time breathing
  • Pressure or pain in the chest that does not go away
  • Bluish lips or face
  • Being unable to stay awake or wake up
  • Confusion

If you or someone you know are experiencing any of these emergency warning signs for COVID-19, please call 911 and seek immediate medical attention.

How does coronavirus disease (COVID-19) spread?

According to the CDC, COVID-19 seems to spread person-to-person, and can be transmitted in one of three ways: direct contact (through touch), droplet (breathing in respiratory droplets of an infected person who is within 6 feet), or airborne (breathing in smaller respiratory droplets of an infected person that tends to stay suspended in the air for a long time)., Most infections are spread through direct contact with an infected person or being within 6 feet of a person who coughs or sneezes could be enough to spread COVID-19. The new coronavirus strain is also able to survive on contaminated objects and surfaces for up to 3 days.9

How contagious is coronavirus?

The coronavirus is very contagious. Many people who are infected with SARS-CoV-2 may not know it until 2–14 days have passed, and symptoms have begun to worsen. By coming into contact with friends, coworkers, and family members, they can unknowingly spread the virus.

Who is at high risk?

There is currently limited information about the exact risk factors associated with the spread of COVID-19. According to the CDC, those who are at high risk include anyone who is:

  • 65 years old or older
  • living in a nursing home or elder care facility -receiving cancer treatment that weakens the immune system, such as chemotherapy
  • immunocompromised due to an existing condition, such as:
  • chronic lung disease
  • moderate to severe asthma
  • serious heart conditions
  • severely obese (BMI > 40)
  • renal failure
  • liver disease
  • diabetes
  • pregnant or expecting
