  • It can spread by hand contact, by direct contact with the infected person or by indirect contact with a contaminated environmental surface.
  • It can also spread by small particle droplets that become airborne from sneezing or coughing.
  • It can also be transmitted via large particle droplets that typically require close contact with infected person.
  • Most important is hand to hand transmission of the virus.
