Coronaviruses usually cause the common cold, though they can be responsible for more severe illnesses.


The name “coronavirus” comes from the crown-like projections on their surfaces. “Corona” in Latin means “halo” or “crown.”

Among humans, coronavirus infections most often occur during the winter months and early spring.


Symptoms of COVID-19

According to the CDC, people may start to experience symptoms 2 to 14 days after exposure to the virus.


The primary symptoms are a cough and shortness of breath or difficulty breathing.

However, according to the CDC, a person with neither of those symptoms may still have COVID-19 if they experience at least two of the following:

  • a fever
  • chills
  • repeated shaking with chills
  • muscle pain
  • a headache
  • a sore throat
  • new loss of taste or smell

No vaccine is currently available for COVID-19. However, scientists have now replicated the virus. This could allow for early detection and treatment in people who have the virus but are not experiencing symptoms.

According to the CDC the following groups have a higher risk of developing serious illness from COVID-19:

  • people aged 65 years or older
  • people living in nursing homes or care facilities
  • people of any age who have serious underlying medical conditions, including chronic lung disease, serious heart conditions, severe obesity, a compromised immune system, or diabetes

The CDC note that although there have been reports of complications in young children, these are rare. COVID-19 most commonly produces mild symptoms in children.
