COVID-19 also has additional elements to consider:

  • COVID-19 is also more contagious and can spread much faster than influenza.
  • People with COVID-19 may also experience a more severe lung infection.
  • People with COVID-19 are at greater risk of dying either during or after infection.
  • In children, COVID-19 can cause a rare, but serious multi-system inflammatory syndrome.
